DX8Wrapper: Deferred State Application + +`Set_Transform(WORLD/VIEW)` does NOT call `D3DDevice->SetTransform` immediately. Matrices are stored in `render_state.world/view` and applied in `Apply_Render_State_Changes()` before each `Draw()`. + +**Critical:** If a function like `Set_World_Identity()` is an empty stub, `render_state.world` remains zeroed → black screen. + +### 2. D3D → Metal Matrix Convention + +D3D stores matrices in row-major order. `memcpy` into Metal `float4x4` (column-major) effectively **transposes** the matrix. The shader uses `P * V * W * pos`, which is equivalent to D3D's `pos * W * V * P`. + +### 3. NSApplication + dispatch_async + +`[NSApp run]` starts the event loop. `dispatch_async(main_queue)` enqueues the game loop. The game loop blocks the main queue (infinite loop). `serviceWindowsOS()` manually pumps events via `[NSApp nextEventMatchingMask:]`. `[CATransaction flush]` is required for window updates. + +### 4. File System Scans CWD + +The game launches from the source code root. `StdLocalFileSystem` scans `.` = thousands of files. The working directory must be set to the ZH data folder via `chdir()` in `MacOSGameEngine::init()`. + +### 5. FVF Stride vs Offset + +`GetPSO` uses stride from the calling code, NOT computed from FVF flags. C++ structs may have padding that differs from the sum of FVF attribute sizes. + +### 6. Half-Pixel Offset (DX8 vs Metal) + +DX8 requires a -0.5px geometry bias for pixel-perfect 2D texel sampling. Metal handles pixel centers correctly at +0.5. The bias is disabled on macOS via `#ifndef __APPLE__` in `render2d.cpp` to prevent shearing artifacts in UI and fonts. + +--- + +## 64-bit Compatibility Fixes + +### Struct Padding (LP64 Data Model) + +On macOS (LP64), `long` is 8 bytes and `void*` is 8 bytes, unlike Windows ILP32 where both are 4 bytes. Several binary file parsers relied on exact struct sizes matching file format headers: + +| File Format | Struct | Problem | Fix | +|:---|:---|:---|:---| +| DDS | `LegacyDDSURFACEDESC2` | `void* Surface` → 132 bytes instead of 124 | Replace with `unsigned int` under `#ifdef __APPLE__` | +| TGA | `TGA2Footer`, `TGA2Extension` | `long` offsets → 34 bytes instead of 26 | Replace with `int` under `#ifdef __APPLE__` | + +### Enum Bitmask Undefined Behavior + +The death/veterancy system uses `1 << enumValue` bitmask mapping. When `enumValue == 0` (DEATH_NORMAL, LEVEL_REGULAR), the bitmask is `1 << 0 = 1`, which maps correctly on 32-bit but causes UB on 64-bit due to sign extension in `BitFlags<>` template. Fixed with explicit bitmask tables in `Damage.h` and `GameCommon.h`. + +### Drawable Lifetime + +`Drawable::drawUIText` could access parent `Object` or `Owner` pointers after the parent was destroyed during the same frame. Fixed with null checks guarded by `#ifdef __APPLE__`. + +--- + +## Multiplayer Architecture + +### Deterministic Math (Cross-Platform Lockstep) + +The game uses lockstep networking — all clients compute game logic in parallel. Any floating-point divergence causes a desync. + +**Problem:** Windows x86 uses 80-bit FPU (`fsin`, `fcos` asm), macOS ARM uses 32-bit NEON/SSE via `sinf()`/`cosf()`. Results differ at the least significant bit. + +**Solution:** All trigonometric functions in `WWMath` are replaced with Sun's `fdlibm` (Freely Distributable LIBM) — a pure C implementation that produces bit-identical IEEE 754 results on all platforms. + +| Function | Old (Windows) | Old (macOS) | New (both) | +|:---|:---|:---|:---| +| Sin, Cos | x87 `fsin`/`fcos` asm | `sinf()`/`cosf()` | `fdlibm_sin()`/`fdlibm_cos()` | +| Sqrt | x87 `fsqrt` asm | `sqrt()` | `fdlibm_sqrt()` | +| Acos, Asin, Atan, Atan2 | system libm | system libm | `fdlibm_*()` | +| Inv_Sqrt | asm Newton-Raphson | `1.0f/sqrt()` | Portable Quake `0x5f3759df` hack | +| Fast_Sin, Fast_Cos | LUT tables | LUT tables | Unchanged (already deterministic) | + +### CRC Verification + +The engine computes CRC checksums every `NET_CRC_INTERVAL` frames (100 in release, 1 in debug). Each player's CRC is compared — any mismatch triggers a desync error. + +The macOS client reports its executable CRC via a server-side version manifest that provides Windows-compatible CRC values, ensuring the P2P handshake succeeds. + +### Online Services (Generals Online) + +~85% of the NGMP (Next-Gen Multiplayer) code is pure C++/STL/libcurl and works cross-platform without changes.

A strategic `+1.0f` Z-offset is applied to water vertices in `W3DWater.cpp` (under `#ifdef __APPLE__`), pushing the water plane slightly above the terrain bed. + +### Destination Alpha +Soft water edges rely on the destination alpha channel in the framebuffer. The water pixel shader writes alpha based on shore proximity, and subsequent terrain passes read this alpha for edge blending. The MSAA `StoreAndMultisampleResolve` action ensures this alpha survives the resolve step. + +--- + +## Two 2D Rendering Paths + +The engine has **two** different paths for 2D content: + +| Path | FVF | Shader | Used by | +|:---|:---|:---|:---| +| **Path A** (`Render2DClass`) | `D3DFVF_XYZ` (0x252) | `useProjection==1` with identity matrices | Buttons, menu text, UI backgrounds | +| **Path B** (`DrawPrimitiveUP`) | `D3DFVF_XYZRHW` | `useProjection==2` with screen→NDC | Radar, shroud overlay | + +### Path A: `Render2DClass` (XYZ + identity) + +`Render2DClass` prepares vertices in NDC coordinates (-1..+1) and sets identity matrices for world/view/projection.

No 3D shell map scene rendered. +- **Root Cause (3 issues):** + 1. **Intro/sizzle state machine broken:** `VideoPlayer::open()` returns `nullptr` on macOS (no video player). + 2. **`showShellMap(TRUE)` never called:** Because the state machine never reached the shell path code. + 3. **`m_breakTheMovie = TRUE` blocked ALL rendering:** `W3DDisplay::draw()` checks this flag

golden rules for working on the macOS port. + +--- + +## 📜 Golden Rules + +1. **Minimize changes to `Core/`** — Platform code lives in `Platform/MacOS/Source/`. Only touch Core with `#ifdef __APPLE__` guards when absolutely necessary. +2. **Minimal `windows.h` shims** — Add stubs only when a build error demands it, never proactively. +3. **`d3d8_stub.h` is the source of truth** — All DX8 interfaces on macOS go through the stub, not the original SDK. +4. **Unified rendering pipeline** — All rendering goes through `MetalDevice8`. No side-channels. +5. **Iterate on crash logs** — Runtime issues are debugged iteratively: crash → log → fix → test. +6. **PRIVATE deps for `zi_always`** — Never let Zero Hour defines leak into the Generals target. +7. **Always `killall generalszh`** — Kill stale processes before launching; Metal layer doesn't release cleanly. +8. **`calloc`, not `malloc`** — On macOS, global allocations use calloc for zero-initialization. +9. **NEVER set `m_breakTheMovie = TRUE`** — `W3DDisplay::draw()` line 1849 checks this flag. When TRUE, `WW3D::Begin_Render()` is skipped and **all 3D rendering is disabled**. +10. **Use `printf` + `fflush(stdout)` for logs** — `fprintf(stderr)` may not appear in redirected logs due to buffering. + +--- + +## 🏗 Architecture + +### Component Map + +| Subsystem | Files | Purpose | +|:---|:---|:---| +| **Metal Backend** | `Source/Metal/MetalDevice8.mm` (85KB+), 5 pairs .h/.mm | DX8 → Metal translator | +| **Entry Point** | `Source/Main/MacOSMain.mm` | NSApplication, game loop, factory functions | +| **Game Client** | `Source/Main/MacOSGameClient.mm` | W3D-compatible game client, shell map bypass | +| **Window** | `Source/Main/MacOSWindowManager.mm` | NSWindow/NSView management | +| **Input** | `Source/Main/StdKeyboard.mm`, `StdMouse.mm` | Cocoa events → game input | +| **Audio** | `Source/Audio/MacOSAudioManager.mm` | AVAudioPlayer backend | +| **Display** | `Source/Client/MacOSDisplay.mm` | CoreText rendering, W3D integration | +| **D3DX Shims** | `Source/Main/D3DXStubs.mm` | `D3DXCreateTextureFromFileEx` etc. | +| **Stubs** | `Source/Stubs/GameSpyStubs.cpp` | 170+ network/Win32 function stubs | +| **Shaders** | `Source/Main/MacOSShaders.metal` | Metal vertex/fragment shaders | + +### Shell Map Loading (macOS specific) + +On macOS there's no video player. The intro/sizzle movie state machine in `GameClient::update()` doesn't complete properly. `MacOSGameClient::update()` bypasses it: + +``` +callCount == 0: + m_playIntro = FALSE + m_afterIntro = FALSE + → GameClient::update() (state machine skipped) + → TheShell->showShellMap(TRUE) (loads ShellMapMD.map) + → TheShell->showShell() (pushes MainMenu.wnd) +``` + +**Key insight:** On Windows, `W3DGameClient::update()` also just calls `GameClient::update()` — no extra logic. The movie state machine works on Windows because `VideoPlayer::open()` returns a valid stream. + +### Stubs Overview + +`GameSpyStubs.cpp` disables all online functionality (~170 functions): +- **Multiplayer:** Online, LAN lobby — not functional +- **Patch system:** Disabled +- **IME:** Disabled +- **Implication:** Engine runs in **single-player mode only** + +--- + +## ⚠️ Critical Gotchas + +### 1. Vtable Mismatch (CMake) + +`macos_platform` is a STATIC library linked by BOTH targets (Generals and Zero Hour). + +**Problem:** Zero Hour's `GameClient.h` has 2 extra virtual methods (`notifyTerrainObjectMoved`, `createSnowManager`) guarded by `#if RTS_ZEROHOUR`. If `RTS_ZEROHOUR` is not defined when compiling `MacOSGameClient.mm`, the vtable layout differs from what the engine library expects → vtable dispatch jumps to wrong addresses. + +**Solution:** +- `zi_always` (provides `RTS_ZEROHOUR=1`) must be a **PRIVATE** dependency of `macos_platform` +- Include paths must point to `GeneralsMD/` (not `Generals/`) +- See `Platform/MacOS/CMakeLists.txt` + +### 2. Global Memory Allocator Conflict + +The game overrides global `operator new`/`delete` to route through `DynamicMemoryAllocator`, which prepends a `MemoryPoolSingleBlock` header. + +**Problem on macOS:** System frameworks (Metal, AppKit, libdispatch) allocate with system `malloc` but free through our overridden `delete`. The allocator tries to read the header from system-allocated memory → crash. + +**Solution:** +```cpp +#ifdef __APPLE__ +void* operator new(size_t size) { + void *p = ::calloc(1, size); // Zero-init! Game relies on this. + if (!p) throw std::bad_alloc(); + return p; +} +void operator delete(void *p) noexcept { + ::free(p); +} +#endif +``` + +**Why `calloc`?** The original custom allocator zeroed memory on allocation. Many game classes have constructors that don't initialize all members (relying on zeroed memory). `malloc` would leave garbage → crashes in constructors like `W3DBridgeBuffer`, `Pathfinder`, etc. + +### 3. Null Globals During Shell Phase + +During menu/shell phase, many game globals are null: `TheGameLogic`, `TheInGameUI`, `TheTacticalView`, `TheScriptEngine`, `TheTerrainVisual`. Additionally, `TheTerrainVisual` is explicitly set to null after init throws `ERROR_BUG`. + +**Pattern:** Always guard access: +```cpp +if (!TheGameLogic || !TheInGameUI) return; +``` + +### 4. `win_compat.h` / Metal Header Conflicts + +Windows API stubs (`LoadResource`, `GetCurrentThread`) conflict with macOS system headers. + +**Solutions used:** +1. `MetalDevice8.h` uses `void*` for all Metal/ObjC types (avoids importing ``) +2. In `.mm` files, macOS framework headers imported **before** `win_compat.h` +3. Conflicting functions wrapped in `#if !defined(__OBJC__)` + +### 5. Mouse Coordinate 2x Scaling + +`Mouse::reset()` sets `m_inputMovesAbsolute = FALSE` (relative mode). In relative mode, `moveMouse()` adds coords to position. Since `StdMouse::addEvent()` also sets position = coords, the position gets doubled. + +**Fix:** `StdMouse::reset()` restores `m_inputMovesAbsolute = TRUE` after calling base `Mouse::reset()`. + +### 6. m_breakTheMovie Flag + +`W3DDisplay::draw()` checks `m_breakTheMovie == FALSE` before `WW3D::Begin_Render()`. If TRUE, **no 3D rendering happens**. On macOS this flag should **never** be set to TRUE. + +### 7. macOS Automatic Termination ⭐ NEW + +macOS has a feature called "Automatic Termination" that silently kills apps it considers idle. Since our game drives its own loop instead of using NSApp's run loop, macOS thinks the app is idle. + +**Symptoms:** Game dies silently ~10s after menu loads. No crash signal, no log output, exit code 0. + +**Solution (all 3 required):** +```objc +[[NSProcessInfo processInfo] disableAutomaticTermination:@"Game is running"]; +[[NSProcessInfo processInfo] disableSuddenTermination]; +// + applicationShouldTerminate: returning NSTerminateCancel +// + Set NSApp delegate BEFORE finishLaunching +``` + +### 8. AudioEventRTS Corrupted Pointers ⭐ NEW + +`AudioManager::processRequestList()` iterates over `m_audioRequests` and accesses `req->m_pendingEvent->getEventName()`. The `AudioEventRTS` objects can be corrupted/dangling by the time `processRequestList()` runs. + +**Symptom:** SIGSEGV in `AsciiString::str()` on 3rd execute() loop iteration. + +**Current workaround:** `processRequestList()` just clears requests without accessing event data. This means **no audio** but no crash. + +**TODO:** Investigate AudioEventRTS ownership — who creates and who deletes these objects. + +### 9. FramePacer Null Globals ⭐ NEW + +`FramePacer::isActualFramesPerSecondLimitEnabled()` accesses `TheScriptEngine->isTimeFast()` without null check (only `TheTacticalView` is checked). Also `TheGlobalData->m_useFpsLimit` accessed without null check. + +**Fix:** Added null checks for both `TheScriptEngine` and `TheGlobalData`. + +### 10. nextDrawable Blocking ⭐ NEW + +`[CAMetalLayer nextDrawable]` blocks indefinitely when `displaySyncEnabled=YES` and the window is not visible/active. There are only 3 drawables in the pool — if all are in flight, it blocks. + +**Fix:** `displaySyncEnabled = NO` + nil guard on drawable return value. Frame rate controlled by `FramePacer`. + +--- + +## 🔄 Development Workflow + +### Typical cycle + +``` +1. Identify crash/issue (from logs or stack trace) +2.

This reduces terrain to 1-2 passes: +- PS does the `lrp` blend (t0↔t1 by vertex alpha) in a single pass +- Noise/cloud stages are added as additional texture fetches within the same PS + +### Terrain Textures + +Terrain uses a **single macro atlas** (`m_stageZeroTexture`) at 1024×1024 (format `fmt=80` = `MTLPixelFormatRGBA8Unorm`).

It only stores the pointer in `m_Textures[]`. The terrain shader binds textures directly via the device: + +```cpp +// Inside TerrainShader2Stage::set(pass): +DX8Wrapper::_Get_D3D_Device8()->SetTexture(0, + W3DShaderManager::getShaderTexture(0)->Peek_D3D_Texture()); +``` + +### Extra Blend Tiles (3-Way Blending) + +When `TheGlobalData->m_use3WayTerrainBlends` is enabled, additional tiles are drawn after the main passes via `renderExtraBlendTiles()`.

Уникальные паттерны движка + +### 2.1 🚨 Все индексы и вершины — `unsigned short` (16-bit!) + +```cpp +// dx8wrapper.h +void Draw(unsigned primitive_type, + unsigned short start_index, + unsigned short polygon_count, + unsigned short min_vertex_index, + unsigned short vertex_count); +``` + +**Движок ограничивает все draw-параметры 16 битами** — max 65535. +Это значит: +- Vertex buffer никогда не будет > 65535 вершин +- Index buffer всегда 16-bit `D3DFMT_INDEX16` +- `CreateVertexBuffer` в MetalDevice8 кастит к `unsigned short` — **это правильно!** + (мы ранее считали это багом, но движок реально ограничен 16 битами) + +### 2.2 🚨 `SetVertexShader` используется для FVF, не для шейдеров + +```cpp +// Apply_Render_State_Changes(), line 2468: +unsigned fvf = render_state.vertex_buffers[i]->FVF_Info().Get_FVF(); +if (fvf != 0) { + Set_Vertex_Shader(fvf); // ← передаёт FVF как "шейдер" +} +``` + +DX8 использует `SetVertexShader()` для двух целей: +1. Установка FVF-кода (если handle < 0x10000) +2. Установка vertex shader handle (если >= 0x10000) + +**Generals uses ONLY FVF** — никогда не создаёт настоящие DX8 vertex/pixel shaders. +Наша заглушка `CreateVertexShader → handle=0;` корректна. + +### 2.3 🚨 Порядок вызовов: Clear() ПЕРЕД BeginScene() + +```cpp +// WW3D pipeline: +DX8Wrapper::Clear(...) // ← вызывает IDirect3DDevice8::Clear() +DX8Wrapper::Begin_Scene(...) // ← вызывает IDirect3DDevice8::BeginScene() +// ... draw calls ... +DX8Wrapper::End_Scene(true) // ← EndScene() + Present() +``` + +**Движок вызывает Clear() ДО BeginScene()!** Это нестандартно для DX8, но допустимо. +Наш MetalDevice8 уже обрабатывает это (auto-BeginScene в Clear, строка 1150). + +### 2.4 🚨 End_Scene сбрасывает ВСЁ + +```cpp +void DX8Wrapper::End_Scene(bool flip_frames) { + DX8CALL(EndScene()); + // ...

Для аддитивных объектов (src=ONE, dst=ONE) +обычный туман не работает (объект должен затухать, а не смешиваться с цветом тумана). +Решение: fogColor = чёрный (0), тогда `mix(0, fragment, fogFactor) = fragment * fogFactor` — +фрагмент просто масштабируется. + +**`FOG_WHITE`** — для мультипликативных объектов (src=ZERO, dst=SRC_COLOR). Туман = белый +означает объект исчезает к белому (нейтральный для умножения). + +→ **Наш Metal-адаптер уже обрабатывает это корректно** через передачу fogColor. + +--- + +## 5.

The screen saver framework is similar to the sample +application framework, using many methods and variables with the same names. +After writing a program with the screen saver framework, you end up with a +fully-functional Microsoft® Windows® screen saver, rather than with a regular +Windows application. +The moire screen saver appears as a mesmerizing sequence of spinning lines and +colors. It uses texture transformation and alpha blending to create a highly +animated scene, even though the polygons that make up the scene do not move +at all. +Path +Source: (SDK root)\Samples\Multimedia\Direct3D\ScreenSavers\Moire +Executable: (SDK root)\Samples\Multimedia\Direct3D\Bin +User's Guide +Moire.scr can be started in five modes: configuration, preview, full, test, and +password-change. You can choose some modes by clicking the right mouse +button (right-click) on the moire.scr file and choosing Configure or Preview. Or +you can start moire.scr from the command line with the following command-line +parameters: +-c Configuration mode +-t Test mode +-p Preview mode +-a Password-change mode +-s Full mode + +============================================================ +=== PAGE 31 === +============================================================ +When the screen saver is running in full mode, press any key or move the mouse +to exit. +Programming Notes +Programs that use the screen saver framework are very similar to programs that +use the Direct3D sample application framework. Each screen saver needs to +create a class derived from the main application class, CD3DScreensaver. To +provide functionality specific to each screen saver, the screen saver implements +its own versions of the virtual functions FrameMove, Render, +InitDeviceObjects, and so forth. +Screen savers can be written to be multimonitor-compatible, without much extra +effort. If you do not want your screen saver to run on multiple monitors, you can +just set the m_bOneScreenOnly variable to TRUE. This value is set to FALSE by +default. The function SetDevice will be called each time the device changes. The +way that moire deals with this is to create a structure called DeviceObjects, +which contains all device-specific pointers and values. CMoireScreensaver holds +an array of DeviceObjects structures, called m_DeviceObjectsArray. When +SetDevice is called, m_pDeviceObjects is changed to point to the DeviceObjects +structure for the specified device. When rendering, m_rcRenderTotal refers to +the rendering area that spans all monitors, and m_rcRenderCurDevice refers to +the rendering area for the current device's monitor. The function +SetProjectionMatrix shows one way to set up a projection matrix that makes +proper use of these variables to either render a scene that spans all the monitors, +or display a copy of the scene on each monitor. The projection matrix used +depends on the value of m_bAllScreensSame, which you can enable the user to +control in the configuration dialog. +The ReadSettings function is called by the screen saver framework at program +startup time, to read various screen saver settings from the registry. DoConfig is +called when the user wants to configure the screen saver settings. The program +should respond to this by creating a dialog box with controls for the various +screen saver settings. This dialog box should also have a button called Display +Settings which, when pressed, should call DoScreenSettingsDialog. This +common dialog box allows the user to configure what renderer and display mode +should be used on each monitor. You should set the member variable +m_strRegPath to a registry path that will hold the screen saver's settings. You +can use this variable in your registry read/write functions. The screen saver + +============================================================ +=== PAGE 32 === +============================================================ +framework will also use this variable to store information about the default +display mode in some cases. +This sample uses common DirectX code that consists of programming elements +such as helper functions. This code is shared with other samples in the DirectX +SDK. You can find the common headers and source code in (SDK +root)\Samples\Multimedia\Common. + +============================================================ +=== PAGE 33 === +============================================================ + +Microsoft DirectX 8.1 (C++) + +============================================================ +=== PAGE 34 === +============================================================ +What's New in DirectX Graphics +This section describes Microsoft® DirectX® graphics features that are new in +DirectX 8.x. +To see what's new in all of DirectX, see What's new in DirectX 8.1. + +============================================================ +=== PAGE 35 === +============================================================ +New Features in DirectX 8.1 +Pixel Shaders +Added pixel shader versions 1.2, 1.3, and 1.4. These new versions expand +existing functionality through a more powerful set of instructions, registers, +and modifiers for programming pixel shaders. +New D3DX Functionality +Mesh API +Added mesh functionality to improve performance using +D3DXConvertMeshSubsetToStrips and +D3DXConvertMeshSubsetToSingleStrip. Use the OptimizedMesh sample +to understand improving mesh performance. +Improved support for progressive meshes with OptimizeBaseLOD, +TrimByVertices and TrimByFaces. +Added D3DXSplitMesh to help split meshes into smaller meshes. +Bump Mapping +Added D3DXComputeTangent to create a per-vertex coordinate system +based on texture coordinate gradients. +D3DXComputeNormalMap converts a height field to a normal map. +MeshView Tool +This tool provides an easy way to load, view, and modify meshes, and +generally exercise Direct3DX (D3DX) functionality on progressive meshes. +This tool is installed as part of the software development kit (SDK) install +and can be accessed from Start/Programs/Microsoft DirectX 8.1 +SDK/DirectX Utilities/DirectX MeshView. For more information about the +tool, see Mesh View Help. +Effect Framework +Effects. Added string support, added comments, and removed FourCC + +============================================================ +=== PAGE 36 === +============================================================ +constraints. +Effect framework API. Support for state saving and restoring, support for +handling OnLost and OnReset, support Set*() after Begin(). All of the +ID3DXTechnique functionality has been moved into the ID3DXEffect +interface to simplify the effect interface. +Texture Library +Implemented a higher quality DXTn encoding algorithm. +Use D3DXGetImageInfoFrom to get image information before loading it. +Includes support for dynamic textures. +D3DXSaveSurfaceToFile supports 8-bit paletted .bmp files and 24-bit RGB +.dds files in all formats: mipmaps, cube maps, volumes. +D3DPOOL_SCRATCH allows creation of resources that are not limited by +device capabilities. They can be created and destroyed, locked and +unlocked. These resources can be set to a device and used in rendering. Use +with D3DX to convert to something useable such as loading a high- +precision height field and converting to a normal map. +Texture fill functions, D3DXFillTexture, D3DXFillCubeTexture, and +D3DXFillVolumeTexture. +Math Library +New math functions: Additional support for spherical quadratic quaternion +interpolation using D3DXQuaternionSquadSetup. Use it with +D3DXQuaternionSquad. D3DXMatrixMultiplyTranspose for matrices in +vertex shaders and D3DXFresnelTerm. +Math library. Added CPU specific optimizations for most important +functions for 3DNow, SSE, and SSE2. +Support for 16-byte aligned matrices using D3DXMATRIXA16. +Samples +Several new samples have been included to demonstrate culling, lighting, +volume fog, and self-shadowing using a shadow volume. +A new screen saver sample is included that is built on the screen saver +sample framework. The new framework includes support for multiple +monitors. +Documentation Upgrades + +============================================================ +=== PAGE 37 === +============================================================ +DXGraphics SDK Docs. The graphics SDK documentation has been +reorganized into two sections: a Reference section and a Programmers +Guide. +New sections for creating programmable vertex shaders, pixel shaders, and +effects have been added to the Programmers Guide. +The global illumination equations and the Mathematics of Lighting section +have been rewritten and examples included. + +============================================================ +=== PAGE 38 === +============================================================ +New Features in DirectX 8.0 +This version maintains backward compatibility by exposing and supporting +objects and interfaces offered by previous releases of DirectX. However, many +new features and performance enhancements have also been added to the +Microsoft Direct3D® API interfaces. +Pixel and Vertex Shaders +The two programmable sections of the Direct3D architecture are vertex +shaders and pixel shaders. Vertex shaders are invoked prior to vertex +assembly and operate on vertices. Pixel shaders are invoked after any +DrawPrimitive or DrawIndexedPrimitive calls and generate the pixels that +are written to the render target. The addition of programmable shaders for +vertex and pixel operations provides the framework for real-time +programmable effects that rival movie quality. The innovative freedom that +this programmability gives back to game developers—by allowing them to +implement whatever effect they see fit with the programmable pipeline— +has the potential to unlock a new round of incredible games. Pixel and +vertex shaders can be written using ASCII files, thus the shader files can be +updated at runtime without recompiling the source application. +Effects +Allows you to change how an object is rendered, based on the hardware +capabilities of the machine your application is running on. Effects are +written using ASCII files, thus the effect file can be updated at runtime +without recompiling the source application. +Complete Integration of DirectDraw and Direct3D +Simplifies application initialization and improves data allocation and +management performance, which reduces the memory footprint. Also, the +integration of the graphics APIs enable parallel vertex input streams for +more flexible rendering. +Multisampling Rendering Support + +============================================================ +=== PAGE 39 === +============================================================ +Enables full-scene antialiasing and multisampling effects, such as motion +blur and depth-of-field. +Point Sprites +Enables high-performance rendering of particle systems for sparks, +explosions, rain, snow, and so on. +3-D Volumetric Textures +Enables range-attenuation in per-pixel lighting and volumetric atmospheric +effects, and can be applied to more intricate geometry. +Higher-Order Primitive Support +Enhances the appearance of three-dimensional (3-D) content and facilitates +the mapping of content from major 3-D authoring tools. +Higher-Level Technologies +Includes 3-D content-creation tool plug-ins (for export to Direct3D) for +skinned meshes that use a variety of Direct3D techniques, multiresolution +level-of-detail (LOD) geometry, and higher-order surface data. +Indexed Vertex Blending +Extends geometry blending support to allow the matrices used for vertex +blending to be referred to using a matrix index. +Expansion of the Direct3DX Utility Library +Contains a wealth of new functionality. The Direct3DX utility library is a +helper layer that sits on top of Direct3D to simplify common tasks +encountered by 3-D graphics developers. Includes a skinning library, +support for working with meshes, and functions to assemble vertex and +pixel shaders. About 20 new functions have been added for DirectX 8.1. +Note that the functionality supplied by D3D_OVERLOADS, first +introduced with DirectX 5.0, has been moved to the Direct3DX utility +library. + +============================================================ +=== PAGE 40 === +============================================================ + +Microsoft DirectX 8.1 (C++) + +============================================================ +=== PAGE 41 === +============================================================ +What's New in DirectInput +New Features for DirectInput 8.1 +Microsoft® DirectX® 8.1 is a major release primarily for DirectX graphics. The +improvements for Microsoft DirectInput® are primarily performance +enhancements. +To find out more about the new features in DirectX, see What's New in DirectX +8.1. + +============================================================ +=== PAGE 42 === +============================================================ +New Features for DirectInput 8.0 +The following are some of the new features in DirectInput. +Action mapping +DirectInput for DirectX 8.0 introduces a major new feature: action +mapping. Action mapping enables you to establish a connection between +input actions and input devices that does not depend on the existence of +particular device objects (such as specific buttons or axes). Action mapping +simplifies the input loop and reduces the need for custom game drivers, +custom device profilers, and custom configuration user interfaces in games. +For more information, see Action Mapping. +New DirectInput object features +The DirectInput object is now represented by the IDirectInput8 interface. +A new helper function, DirectInput8Create, creates the object and +retrieves this interface. IDirectInput8 has a new CLSID and cannot be +obtained by calling QueryInterface on an interface to objects of the class +CLSID_DirectInput used in earlier DirectX versions. +New keyboard properties +Two keyboard properties have been added: DIPROP_KEYNAME, which +retrieves a localized key name, and DIPROP_SCANCODE, which retrieves +the scan code. +Joystick slider data in rglSlider array +Joystick slider data that was assigned to the z-axis of a DIJOYSTATE or +DIJOYSTATE2 structure under earlier DirectX versions will now be found +in the rglSlider array of those same structures. + +============================================================ +=== PAGE 43 === +============================================================ + +Microsoft DirectX 8.1 (pixel shader versions 1.0, 1.1, 1.2, 1.3, 1.4) + +============================================================ +=== PAGE 44 === +============================================================ +Instructions +Pixel shaders contain the following types of instructions. +A Version instruction defines the shader version. There is only one version +instruction in a shader and it is the first instruction in a shader. +Constant instructions define constants. These instructions must be after the +version instruction and before any arithmetic or texture address instructions. +A Phase instruction splits a shader into two sections: phase 1 and phase 2. +Each phase has separate arithmetic and texture address instruction limits. +Version 1.4 is the only version that supports the phase instruction. +Arithmetic instructions include common mathematical operations such as +add and subtract, multiply, and taking a dot product. +Texture Address instructions manipulate texture coordinate data that is +associated with texture stages. +The instructions are listed below. +Version instructions +Version +1.0 1.1 1.2 1.3 1.4 +ps +x +x +x +x +x +Constant instructions +Version +1.0 1.1 1.2 1.3 1.4 +def +x +x +x +x +x +Phase instructions +Version +1.0 1.1 1.2 1.3 1.4 +phase +x +Arithmetic instructions +Version +1.0 1.1 1.2 1.3 1.4 +add +x +x +x +x +x +bem +x +cmp +x +x +x +cnd +x +x +x +x +x +dp3 +x +x +x +x +x +dp4 +x +x +x + +============================================================ +=== PAGE 45 === +============================================================ +lrp +x +x +x +x +x +mad +x +x +x +x +x +mov +x +x +x +x +x +mul +x +x +x +x +x +nop +x +x +x +x +x +sub +x +x +x +x +x +Texture address instructions +Version +1.0 1.1 1.2 1.3 1.4 +tex +x +x +x +x +texbem +x +x +x +x +texbeml +x +x +x +x +texcoord +x +x +x +x +texcrd +x +texdepth +x +texdp3 +x +x +texdp3tex +x +x +texkill +x +x +x +x +x +texld +x +texm3x2depth +x +texm3x2pad +x +x +x +x +texm3x2tex +x +x +x +x +texm3x3 +x +x +texm3x3pad +x +x +x +x +texm3x3tex +x +x +x +x +texm3x3spec +x +x +x +x +texm3x3vspec +x +x +x +x +texreg2ar +x +x +x +x +texreg2gb +x +x +x +x +texreg2rgb +x +x + +============================================================ +=== PAGE 46 === +============================================================ + +Microsoft Directx 8.1 (pixel shader versions 1.0, 1.1, 1.2, 1.3, 1.4) + +============================================================ +=== PAGE 47 === +============================================================ +Registers +Registers hold data for use by the pixel shader.

Details the restrictions on using multiple registers in a +single instruction. +Read-only, Read/Write. Describes which registers can be used for reading, +writing, or both. +Range. Details the range of the component data. +Register Types +Registers transfer data to the shader ALU and store temporary results. The table +below identifies the four types of registers and the number available in each +shader version. +Register name +Type +Versions +1.0 1.1 1.2 1.3 +1.4 +cn +Constant register +8 +8 +8 +8 +8 +rn +Temporary register 2 +2 +2 +2 +6 +tn +Texture register +4 +4 +4 +4 +6 +vn +Color register +2 +2 +2 +2 +2 in phase 2 +Constant registers contain constant data organized in four fixed-point +values. Data can be loaded into a constant register using +SetPixelShaderConstant or it can be defined using the def shader +instruction. Constant registers are not usable by texture address instructions. +The only exception is the texm3x3spec instruction, which uses a constant +register to supply an eye-ray vector. +Temporary registers are used to store intermediate results, as four fixed- +point values. r0 additionally serves as the pixel shader output. The value in +r0 at the end of the shader is the pixel color for the shader. + +============================================================ +=== PAGE 48 === +============================================================ +Shader pre-processing will fail CreatePixelShader on any shader that +attempts to read from a temporary register that has not been written by a +previous instruction. D3DXAssembleShader will fail similarly, assuming +validation is enabled (do not use D3DXASM_SKIPVALIDATION). +Texture registers +Pixel shader version 1.1 to 1.3 +For pixel shader version 1.1 to 1.3, texture registers contain texture +data, organized in four fixed-point values. Texture data is loaded into a +texture register when a texture is sampled. Texture sampling uses +texture coordinates to look up, or sample, a color value at the specified +(u,v,w,q) coordinates while taking into account the texture stage state +attributes. The texture coordinate data is interpolated from the vertex +texture coordinate data and is associated with a specific texture stage. +There is a default one-to-one association between texture stage number +and texture coordinate declaration order. By default, the first set of +texture coordinates defined in the vertex format is associated with +texture stage 0. +For these pixel shader versions, texture registers behave just like +temporary registers when used by arithmetic instructions. For pixel +shader version 1.0, texture registers are read-only to arithmetic +instructions. +Pixel shader version 1.4 +For pixel shader version 1.4, texture registers (t#) contain read-only +texture coordinate data. This means that the texture coordinate set and +the texture stage number are independent from each other. The texture +stage number (from which to sample a texture) is determined by the +destination register number (r0 to r5). For the texld instruction, the +texture coordinate set is determined by the source register (t0 to t5), so +the texture coordinate set can be mapped to any texture stage. In +addition, the source register (specifying texture coordinates) for texld +can also be a temporary register (r#), in which case the contents of the +temporary register are used as texture coordinates. +For this pixel shader version, texture registers contain texture + +============================================================ +=== PAGE 49 === +============================================================ +coordinate data and are also available to texture addressing +instructions as source parameters. +Color registers contain per-pixel color values. The values are obtained by +per-pixel iteration of the diffuse and specular color values in the vertex +data. Color registers store data in four fixed-point values. For pixel shader +version 1.4 shaders, color registers are available only during the second +phase. +If the shade mode is set to D3DSHADE_FLAT, the application iteration of +both vertex colors (diffuse and specular) is disabled. Regardless of the +shade mode, fog will still be iterated by the pipeline if pixel fog is enabled. +Keep in mind that fog is applied later in the pipeline than the pixelshader. +It is common to load the v0 register with the vertex diffuse color data. It is +also common to load the v1 register with the vertex specular color data. +Input color data values are clamped (saturated) to the range 0 through 1 +because this is the valid input range for color registers in the pixel shader. +Pixel shaders have read only access to color registers. The contents of these +registers are iterated values, but iteration is performed at much lower +precision than texture coordinates. +Read Port Limit +The read port limit specifies the number of different registers of each register +type that can be used as a source register in a single instruction. +Register name +Type +Versions +1.0 1.1 1.2 1.3 1.4 +cn +Constant register +2 +2 +2 +2 +2 +rn +Temporary register 2 +2 +2 +2 +3 +tn +Texture register +1 +2 +3 +3 +1 +vn +Color register +1 +2 +2 +2 +2 +For example, the color registers for almost all versions have a read port limit of + +============================================================ +=== PAGE 50 === +============================================================ +two. This means that a single instruction can use a maximum of two different +color registers (v0 and v1 for instance) as source registers.

The user sets attributes of the pipeline that control how Direct3D +transforms, lights, and renders pixels. The fixed function vertex format is +declared at compile time and determines the input vertex format. Once defined, +the user has little control over pipeline changes during runtime. +Programmable shaders add a new dimension to the graphics pipeline by allowing +the transform, lighting, and rendering functionality to be modified at runtime. A +shader is declared at runtime but, once done, the user is free to change which +shader is active as well as to control the shader data dynamically using streaming +data. This gives the user a new level of dynamic flexibility over the way that +pixels are rendered. +A vertex shader file contains vertex shader instructions. Vertex shaders can +control vertex color and how textures are applied to vertices. Lighting can be +added through the use of vertex shader instructions. The shader instruction file +contains ASCII text so it is readable and in some ways looks similar to assembly +language. A vertex shader is invoked after any DrawPrimitive or +DrawIndexedPrimitive call. Shaders can be dynamically switched using +SetVertexShader to specify a new shader file, or by changing the instructions in +the ASCII text shader file using the streaming data inputs. The Vertex Shader +Assembler Reference has a complete listing of shader instructions. +For additional information, see the following sections. +Create a Vertex Shader +This section contains a code sample that uses a vertex shader to apply a +constant color to object vertices.

The user sets attributes of the pipeline that control how Direct3D +transforms, lights, and renders pixels. The fixed function vertex format is +declared at compile time and determines the input vertex format. Once defined, +the user has little control over pipeline changes during run time. +Shaders add a new dimension to the graphics pipeline by allowing the vertex +transform, lighting, and individual pixel coloring functionality to be +programmed. Pixel shaders are short programs that execute for each pixel when +triangles are rasterized. This gives the user a new level of dynamic flexibility +over the way that pixels are rendered. +A pixel shader contains pixel shader instructions made up of ASCII text. +Arithmetic instructions can be used to apply diffuse and/or specular color. +Texture addressing instructions provide a variety of operations for reading and +applying texture data. Functionality is available for masking and swapping color +components. The shader ASCII text looks similar to assembly language and is +assembled using Direct3DX assembler functions from either a text string or a +file. The assembler output is a series of opcodes that an application may provide +to Direct3D by means of IDirect3DDevice8::CreatePixelShader. The Pixel +Shader Reference has a complete listing of shader instructions. +To understand more about pixel shaders, see the following sections. +Create a Pixel Shader contains a code sample that uses a pixel shader to +apply Gouraud interpolated diffuse colors to an object. This example +contains a detailed explanation of the methods used. +Texture Considerations details the texture stage states that are ignored +during pixel shaders. +Confirming Pixel Shader Support gives a more detailed explanation of the +structures for enumerating pixel shader support. +Pixel Shader Examples shows more code samples that add textures and +blend vertex colors and textures. +Converting Texture Operations gives examples of converting texture +operations to pixel shader instructions. + +============================================================ +=== PAGE 113 === +============================================================ +Debugging provides debugging information. + +============================================================ +=== PAGE 114 === +============================================================ + +Microsoft DirectX 8.1 (C++) + +============================================================ +=== PAGE 115 === +============================================================ +Effects +Microsoft® Direct3D® provides a rich feature set for creating complex and +visually realistic three-dimensional (3-D) scenes. Effect files help you write an +application that uses all the rendering capabilities for the hardware on which it +runs. Effects are a collection of different rendering techniques that can fit onto a +variety of hardware devices. +For example, to create a realistic rippled pond of water that reflects light as +shown in the following image, you begin with the first technique that renders the +water, adds specular highlights, adds caustic textures, and applies light to the +water in a single pass. If your hardware cannot render this technique in a single +pass, a second technique might render the water, add specular highlights or +caustic textures, but not apply light to the water. +Before you use a technique, you can validate it using Direct3D to see if it is +supported by the current hardware configuration. +Effects are defined in an effect file. An effect file consists of one or more +techniques. Each technique consists of one or more passes. These files are text +based and can be changed without recompiling the source application. This +enables you to program games that make optimum use of video card +functionality. Effect files also make it easy to upgrade an existing game to run on +newer video cards as additional features are developed. +The following topics discuss effects and how you can use them in your +application. +Create an Effect +Multiple Techniques + +============================================================ +=== PAGE 116 === +============================================================ +Exercises* +*From the DirectX Meltdown 2001 conference, Programmable Shader +workshop. +Exercise 1 - Fixed Function Diffuse Lighting and Vertex Shader Diffuse +Lighting. +Exercise 2 - Vertex Shader Diffuse Lighting.

This is enough flexibility to solve a wide range of lighting +situations. You refer to the total amount of light in a scene as the global +illumination and compute it using the following equation. +Global Illumination = Ambient Light + Diffuse Light + Specular Light +Ambient lighting is constant lighting. It is constant in all directions and it colors +all pixels of an object the same. It is fast to calculate but leaves objects looking +flat and unrealistic. To see how ambient lighting is calculated by Direct3D, see +Ambient Lighting. +Diffuse lighting depends on both the light direction and the object surface +normal. It varies across the surface of an object as a result of the changing light +direction and the changing surface numeral vector. It takes longer to calculate +diffuse lighting because it changes for each object vertex, however the benefit of +using it is that it shades objects and gives them three-dimensional (3-D) depth. +To see how diffuse lighting is calculated in Direct3D, see Diffuse Lighting. +Specular lighting identifies the bright specular highlights that occur when light +hits an object surface and reflects back toward the camera. It is more intense +than diffuse light and falls off more rapidly across the object surface. It takes +longer to calculate specular lighting than diffuse lighting, however the benefit of +using it is that it adds significant detail to a surface. To see how specular lighting +is calculated in Direct3D, see Specular Lighting. +Emissive lighting is light that is emitted by an object, for example, a glow. To +see how emissive lighting is calculated in Direct3D, see Emissive Lighting. +Realistic lighting can be accomplished by applying each of these types of +lighting to a 3-D scene. To achieve a more realistic lighting effect, you add more +lights; however, the scene takes longer to render. To achieve all the effects a +designer wants, some games use more CPU power than is commonly available. +In this case, it is typical to reduce the number of lighting calculations to a +minimum by using lighting maps and environment maps to add lighting to a +scene while using texture maps. + +============================================================ +=== PAGE 119 === +============================================================ +All lighting computations are made in model space by transforming the light +source's position and direction, along with the camera position, to model space +using the inverse of the world matrix. As a result, if the world or view matrices +introduce non-uniform scaling, the resultant lighting might be inaccurate. To see +how lighting transformations are calculated, see Camera Space Transformations. +Diffuse and specular light values can be affected by a given light's attenuation +and spotlight characteristics. Terms for both of these are included in the diffuse +and specular equations. For more information, see Attenuation and Spotlight +Terms. + +============================================================ +=== PAGE 120 === +============================================================ + +Microsoft DirectX 8.1 (C++) + +============================================================ +=== PAGE 121 === +============================================================ +Action Mapping +Traditionally, applications have done their own mapping of events to particular +buttons and axes. A car-racing game, for example, might assume that the x-axis +on the user's joystick or mouse was the most suitable control for steering the car. +The only way to accommodate new or unusual devices was to provide +configuration options so that the user could specify some other axis, such as a +rotational axis, to use for steering. Moreover, the application had no way of +knowing which installed device was the best fit for the game, so the user +typically had to choose a device from a menu or make sure only the preferred +device was attached. +Using action mapping, you no longer need to make assumptions about the best +use of devices and device objects. Instead, your application binds actions to +virtual controls wherever possible. Rather than getting data from the x-axis and +steering the car to the left or the right accordingly, the application might get data +from a virtual control called DIAXIS_DRIVINGR_STEER. Microsoft® +DirectInput® assigns the virtual control to a physical control—that is, a device +object. It does so by taking into account the application genre, user preferences, +information from the device manufacturer, and the user's configuration of the +device. +Action mapping also simplifies the input loop by returning data for all devices in +a form independent of the particular device. A single action can be mapped to +more than one device, and the input loop can respond to the action the same way +regardless of which device is being read. +The following topics contain more information on the steps required to +implement action mapping. +Preparing the Action Map +Finding Matching Devices +Configuring the Action Map +User Configuration of the Device +Retrieving Action Data +Maintaining Files During Development + +============================================================ +=== PAGE 122 === +============================================================ + +Microsoft DirectX 8.1 (C++) + +============================================================ +=== PAGE 123 === +============================================================ +IDirectInput8 +Applications use the methods of the IDirectInput8 interface to enumerate, +create, and retrieve the status of Microsoft® DirectInput® devices, initialize the +DirectInput object, and invoke an instance of the Microsoft Windows® Control +Panel. +IDirectInput8 supersedes the IDirectInput, IDirectInput2, and IDirectInput7 +interfaces used in earlier versions of Microsoft DirectX®. +IDirectInput8 is an interface to a new class of object, represented by the class +identifier CLSID_DirectInput8, and cannot be obtained by calling +QueryInterface on an interface to objects of class CLSID_DirectInput.

Only texture coordinates set on this +texture stage are relevant. +When using texcrd, keep in mind the following detail about how data is copied +from the source register to the destination register. The source texture coordinate +register (t#) holds data in the range [-D3DCAPS8.MaxTextureRepeat, +D3DCAPS8.MaxTextureRepeat], while the destination register (r#) can hold +data only in the (likely smaller) range [-D3DCAPS8.MaxPixelShaderValue, +D3DCAPS8.MaxPixelShaderValue]. Note that for pixel shader version 1.4, +D3DCAPS8.MaxPixelShaderValue must be a minimum of eight. The texcrd +instruction, in the process of clamping source data that is out of range of the +destination register, is likely to behave differently on different hardware. The +first pixel shader version 1.4 hardware on the market will perform a special +clamp for values outside of range. This clamp is designed to produce a number + +============================================================ +=== PAGE 200 === +============================================================ +that can fit into the destination register, but also to preserve texture addressing +behavior for out-of-range data (see D3DTEXTUREADDRESS) if the data were +to be subsequently used for texture sampling. However, new hardware from +different manufacturers might not exhibit this behavior and might simply chop +data to fit the destination register range. Therefore, the safest course of action +when using pixel shader version 1.4 texcrd is to supply texture coordinate data +only into the pixel shader that is already within the range [-8,8] so that you do +not rely on the way hardware clamps. +Unlike texcoord, texcrd does not clamp values between 0 and 1. +Rules for using texcrd: +1.

This ordinal is +valid only to pass to methods of the IDirect3D8 interface that created this +Direct3DDevice object. The IDirect3D8 interface can always be retrieved +by calling IDirect3DDevice8::GetDirect3D. +Caps +The following driver-specific capability. +D3DCAPS_READ_SCANLINE +Display hardware is capable of returning the current scan line. +Caps2 + +============================================================ +=== PAGE 257 === +============================================================ +The following driver-specific capabilities. +D3DCAPS2_CANCALIBRATEGAMMA +The system has a calibrator installed that can automatically adjust the +gamma ramp so that the result is identical on all systems that have a +calibrator. To invoke the calibrator when setting new gamma levels, +use the D3DSGR_CALIBRATE flag when calling the +IDirect3DDevice8::SetGammaRamp method. Calibrating gamma +ramps incurs some processing overhead and should not be used +frequently. +D3DCAPS2_CANRENDERWINDOWED +The driver is capable of rendering in windowed mode. +D3DCAPS2_CANMANAGERESOURCE +The driver is capable of managing resources. On such drivers, +D3DPOOL_MANAGED resources will be managed by the driver. To +have Direct3D override the driver so that Direct3D manages resources, +use the D3DCREATE_DISABLE_DRIVER_MANAGEMENT flag +when calling IDirect3D8::CreateDevice +D3DCAPS2_DYNAMICTEXTURES +The driver supports dynamic textures. +D3DCAPS2_FULLSCREENGAMMA +The driver supports dynamic gamma ramp adjustment in full-screen +mode. +D3DCAPS2_NO2DDURING3DSCENE +When the D3DCAPS2_NO2DDURING3DSCENE capability is set by +the driver, it means that 2-D operations cannot be performed between +calls to IDirect3DDevice8::BeginScene and +IDirect3DDevice8::EndScene. +Typically, this capability is set by hardware that partitions the scene +and then renders each partition in sequence. The partitioning is +performed in the driver, and the hardware contains a small color and +depth buffer that corresponds to the size of the image partition. +Typically, on this type of rendering hardware, once each part of the +image is rendered, the data in the color buffers are written to video +memory and the contents of the depth buffer are discarded. Also, note +that 3-D rendering does not start until EndScene is encountered. Next, +the scene is processed in regions. Therefore, the processing order +cannot be guaranteed. For example, the first region that is processed, +typically the upper left corner of the window, might include the last + +============================================================ +=== PAGE 258 === +============================================================ +triangle in the frame. This differs from more traditional graphics +systems in which each command is processed sequentially in the order +that it was sent. The 2-D operations are implied to occur at some fixed +point in the processing. In the systems that set +D3DCAPS2_NO2DDURING3DSCENE, the processing order is not +guaranteed. Therefore, the display adapter might discard 2-D +operations that are encountered during 3-D rendering. +In general, it is recommended that 2-D operations be performed +outside of a BeginScene and EndScene pair. If 2-D operations are to +be performed between a BeginScene and EndScene pair, then it is +necessary to check the D3DCAPS2_NO2DDURING3DSCENE +capability. If it is set, the application must expect that any 2-D +operation that occurs between BeginScene and EndScene will be +discarded. For more information on writing applications for systems +that set D3DCAPS2_NO2DDURING3DSCENE, see Remarks. +D3DCAPS2_RESERVED +Reserved; not used. +Caps3 +The following driver-specific capabilities. +D3DCAPS3_ALPHA_FULLSCREEN_FLIP_OR_DISCARD +The device will work as expected with the +D3DRS_ALPHABLENDENABLE render state when a full-screen +application uses D3DSWAPEFFECT_FLIP or +D3DRS_SWAPEFFECT_DISCARD. +D3DRS_ALPHABLENDENABLE works as expected when using +D3DSWAPEFFECT_COPY and D3DSWAPEFFECT_COPYSYNC. +D3DCAPS3_RESERVED +Reserved; not used. +PresentationIntervals +Bit mask of values representing what presentation swap intervals are +available. +D3DPRESENT_INTERVAL_IMMEDIATE +The driver supports an immediate presentation swap interval. +D3DPRESENT_INTERVAL_ONE +The driver supports a presentation swap interval of every screen +refresh. +D3DPRESENT_INTERVAL_TWO + +============================================================ +=== PAGE 259 === +============================================================ +The driver supports a presentation swap interval of every second +screen refresh. +D3DPRESENT_INTERVAL_THREE +The driver supports a presentation swap interval of every third screen +refresh. +D3DPRESENT_INTERVAL_FOUR +The driver supports a presentation swap interval of every fourth screen +refresh. +CursorCaps +Bit mask indicating what hardware support is available for cursors. +D3DCURSORCAPS_COLOR +A full-color cursor is supported in hardware. Specifically, this flag +indicates that the driver supports at least a hardware color cursor in +high-resolution modes (with scan lines greater than or equal to 400). +D3DCURSORCAPS_LOWRES +A full-color cursor is supported in hardware. Specifically, this flag +indicates that the driver supports a hardware color cursor in both high- +resolution and low-resolution modes (with scan lines less than 400). +Direct3D does not define alpha-blending cursor capabilities. +DevCaps +Flags identifying the capabilities of the device. +D3DDEVCAPS_CANBLTSYSTONONLOCAL +Device supports blits from system-memory textures to nonlocal video- +memory textures. +D3DDEVCAPS_CANRENDERAFTERFLIP +Device can queue rendering commands after a page flip. Applications +do not change their behavior if this flag is set; this capability simply +means that the device is relatively fast. +D3DDEVCAPS_DRAWPRIMTLVERTEX +Device exports a DrawPrimitive-aware hardware abstraction layer +(HAL). +D3DDEVCAPS_EXECUTESYSTEMMEMORY +Device can use execute buffers from system memory. +D3DDEVCAPS_EXECUTEVIDEOMEMORY +Device can use execute buffers from video memory. +D3DDEVCAPS_HWRASTERIZATION +Device has hardware acceleration for scene rasterization. + +============================================================ +=== PAGE 260 === +============================================================ +D3DDEVCAPS_HWTRANSFORMANDLIGHT +Device can support transformation and lighting in hardware. +D3DDEVCAPS_NPATCHES +Device supports N-patches. +D3DDEVCAPS_PUREDEVICE +Device can support rasterization, transform, lighting, and shading in +hardware. +D3DDEVCAPS_QUINTICRTPATCHES +Device supports quintic Bézier curves and B-splines. +D3DDEVCAPS_RTPATCHES +Device supports rectangular and triangular patches. +D3DDEVCAPS_RTPATCHHANDLEZERO +When this device capability is set, the hardware architecture does not +require caching of any information, and uncached patches (handle +zero) will be drawn as efficiently as cached ones. Note that setting +D3DDEVCAPS_RTPATCHHANDLEZERO does not mean that a +patch with handle zero can be drawn. A handle-zero patch can always +be drawn whether this cap is set or not. +D3DDEVCAPS_SEPARATETEXTUREMEMORIES +Device is texturing from separate memory pools. +D3DDEVCAPS_TEXTURENONLOCALVIDMEM +Device can retrieve textures from non-local video memory. +D3DDEVCAPS_TEXTURESYSTEMMEMORY +Device can retrieve textures from system memory. +D3DDEVCAPS_TEXTUREVIDEOMEMORY +Device can retrieve textures from device memory. +D3DDEVCAPS_TLVERTEXSYSTEMMEMORY +Device can use buffers from system memory for transformed and lit +vertices. +D3DDEVCAPS_TLVERTEXVIDEOMEMORY +Device can use buffers from video memory for transformed and lit +vertices. +PrimitiveMiscCaps +General capabilities for this primitive. This member can be one or more of +the following flags. +D3DPMISCCAPS_BLENDOP +Device supports the alpha-blending operations defined in the +D3DBLENDOP enumerated type. +D3DPMISCCAPS_CLIPPLANESCALEDPOINTS + +============================================================ +=== PAGE 261 === +============================================================ +Device correctly clips scaled points of size greater than 1.0 to user- +defined clipping planes. +D3DPMISCCAPS_CLIPTLVERTS +Device clips post-transformed vertex primitives. +D3DPMISCCAPS_COLORWRITEENABLE +Device supports per-channel writes for the render target color buffer +through the D3DRS_COLORWRITEENABLE state. +D3DPMISCCAPS_CULLCCW +The driver supports counterclockwise culling through the +D3DRS_CULLMODE state. (This applies only to triangle primitives.) +This flag corresponds to the D3DCULL_CCW member of the +D3DCULL enumerated type. +D3DPMISCCAPS_CULLCW +The driver supports clockwise triangle culling through the +D3DRS_CULLMODE state. (This applies only to triangle primitives.) +This flag corresponds to the D3DCULL_CW member of the +D3DCULL enumerated type. +D3DPMISCCAPS_CULLNONE +The driver does not perform triangle culling. This corresponds to the +D3DCULL_NONE member of the D3DCULL enumerated type. +D3DPMISCCAPS_LINEPATTERNREP +The driver can handle values other than 1 in the wRepeatFactor +member of the D3DLINEPATTERN structure. (This applies only to +line-drawing primitives.) +D3DPMISCCAPS_MASKZ +Device can enable and disable modification of the depth buffer on +pixel operations. +D3DPMISCCAPS_TSSARGTEMP +Device supports D3DTA_TEMP for temporary register. +RasterCaps +Information on raster-drawing capabilities. This member can be one or +more of the following flags. +D3DPRASTERCAPS_ANISOTROPY +Device supports anisotropic filtering. +D3DPRASTERCAPS_ANTIALIASEDGES +Device can antialias lines forming the convex outline of objects.

In range-based fog, the distance of +an object from the viewer is used to compute fog effects, not the depth +of the object (that is, the z-coordinate) in the scene. +D3DPRASTERCAPS_FOGTABLE +Device calculates the fog value by referring to a lookup table +containing fog values that are indexed to the depth of a given pixel. +D3DPRASTERCAPS_FOGVERTEX +Device calculates the fog value during the lighting operation, and +interpolates the fog value during rasterization. +D3DPRASTERCAPS_MIPMAPLODBIAS +Device supports level-of-detail (LOD) bias adjustments. These bias +adjustments enable an application to make a mipmap appear crisper or +less sharp than it normally would. For more information about LOD +bias in mipmaps, see D3DTSS_MIPMAPLODBIAS. +D3DPRASTERCAPS_PAT +The driver can perform patterned drawing lines or fills with +D3DRS_LINEPATTERN for the primitive being queried. +D3DPRASTERCAPS_STRETCHBLTMULTISAMPLE +Device provides limited multisample support through a stretch-blt +implementation. When this capability is set, +D3DRS_MULTISAMPLEANTIALIAS cannot be turned on and off in +the middle of a scene. Multisample masking cannot be performed if +this flag is set. +D3DPRASTERCAPS_WBUFFER +Device supports depth buffering using w. +D3DPRASTERCAPS_WFOG +Device supports w-based fog. W-based fog is used when a perspective +projection matrix is specified, but affine projections still use z-based +fog. The system considers a projection matrix that contains a nonzero +value in the [3][4] element to be a perspective projection matrix. +D3DPRASTERCAPS_ZBIAS +Device supports z-bias values. These are integer values assigned to +polygons that allow physically coplanar polygons to appear separate. +For more information, see D3DRS_ZBIAS. +D3DPRASTERCAPS_ZBUFFERLESSHSR +Device can perform hidden-surface removal (HSR) without requiring + +============================================================ +=== PAGE 263 === +============================================================ +the application to sort polygons and without requiring the allocation of +a depth buffer. This leaves more video memory for textures. The +method used to perform HSR is hardware-dependent and is transparent +to the application. +Z-bufferless HSR is performed if no depth-buffer surface is associated +with the rendering-target surface and the depth-buffer comparison test +is enabled (that is, when the state value associated with the +D3DRS_ZENABLE enumeration constant is set to TRUE). +D3DPRASTERCAPS_ZFOG +Device supports z-based fog. +D3DPRASTERCAPS_ZTEST +Device can perform z-test operations. This effectively renders a +primitive and indicates whether any z pixels have been rendered. +ZCmpCaps +Z-buffer comparison capabilities. This member can be one or more of the +following flags. +D3DPCMPCAPS_ALWAYS +Always pass the z test. +D3DPCMPCAPS_EQUAL +Pass the z test if the new z equals the current z. +D3DPCMPCAPS_GREATER +Pass the z test if the new z is greater than the current z. +D3DPCMPCAPS_GREATEREQUAL +Pass the z test if the new z is greater than or equal to the current z. +D3DPCMPCAPS_LESS +Pass the z test if the new z is less than the current z. +D3DPCMPCAPS_LESSEQUAL +Pass the z test if the new z is less than or equal to the current z. +D3DPCMPCAPS_NEVER +Always fail the z test. +D3DPCMPCAPS_NOTEQUAL +Pass the z test if the new z does not equal the current z. +SrcBlendCaps +Source-blending capabilities.

(The RGBA values of the source and destination are +indicated by the subscripts s and d.) +D3DPBLENDCAPS_BOTHINVSRCALPHA + +============================================================ +=== PAGE 264 === +============================================================ +Source blend factor is (1–As, 1–As, 1–As, 1–As), and destination blend +factor is (As, As, As, As); the destination blend selection is overridden. +D3DPBLENDCAPS_BOTHSRCALPHA +The driver supports the D3DBLEND_BOTHSRCALPHA blend mode. +(This blend mode is obsolete.

This member can be the same capabilities +that are defined for the SrcBlendCaps member. +AlphaCmpCaps +Alpha-test comparison capabilities. This member can include the same +capability flags defined for the ZCmpCaps member. If this member +contains only the D3DPCMPCAPS_ALWAYS capability or only the +D3DPCMPCAPS_NEVER capability, the driver does not support alpha +tests. Otherwise, the flags identify the individual comparisons that are + +============================================================ +=== PAGE 265 === +============================================================ +supported for alpha testing. +ShadeCaps +Shading operations capabilities. It is assumed, in general, that if a device +supports a given command at all, it supports the D3DSHADE_FLAT mode +(as specified in the D3DSHADEMODE enumerated type). This flag +specifies whether the driver can also support Gouraud shading and whether +alpha color components are supported. When alpha components are not +supported, the alpha value of colors generated is implicitly 255. This is the +maximum possible alpha (that is, the alpha component is at full intensity). +The color, specular highlights, fog, and alpha interpolants of a triangle each +have capability flags that an application can use to find out how they are +implemented by the device driver. +This member can be one or more of the following flags. +D3DPSHADECAPS_ALPHAGOURAUDBLEND +Device can support an alpha component for Gouraud-blended +transparency (the D3DSHADE_GOURAUD state for the +D3DSHADEMODE enumerated type). In this mode, the alpha color +component of a primitive is provided at vertices and interpolated +across a face, along with the other color components. +D3DPSHADECAPS_COLORGOURAUDRGB +Device supports Gouraud shading. In this mode, the red, green, and +blue components for a primitive are provided at vertices and +interpolated across a face. +D3DPSHADECAPS_FOGGOURAUD +Device supports Gouraud shading of fog. +D3DPSHADECAPS_SPECULARGOURAUDRGB +Device supports Gouraud shading of specular highlights. +TextureCaps +Miscellaneous texture-mapping capabilities.

A device that exposes this capability can use such a +texture if all of the following requirements are met. +The texture addressing mode for the texture stage is set to +D3DTADDRESS_CLAMP. +Texture wrapping for the texture stage is disabled (D3DRS_WRAPn +set to 0). +Mipmapping is not in use (use magnification filter only). +Texture formats must not be DXT1-5 +A texture that is not a power of two cannot be set at a stage that will be read +based on a shader computation (such as the bem, beml, or texm3x3 +instructions in pixel shaders versions 1.0 to 1.3). For example, these +textures can be used to store bumps that will be fed into texture reads, but +not the environment maps that are used in texbem, texbeml, or +texm3x3spec. This means that a texture with dimensions that are not +powers of two cannot be addressed or sampled using texture coordinates +computed within the shader. This type of operation is known as a dependent +read and cannot be performed on these kinds of textures. +D3DPTEXTURECAPS_PERSPECTIVE +Perspective correction texturing is supported. +D3DPTEXTURECAPS_POW2 +All textures must have widths and heights specified as powers of 2. +This requirement does not apply to either cube textures or volume +textures. +D3DPTEXTURECAPS_PROJECTED +Supports the D3DTTFF_PROJECTED texture transformation flag. + +============================================================ +=== PAGE 267 === +============================================================ +When applied, the device divides transformed texture coordinates by +the last texture coordinate. If this capability is present, then the +projective divide occurs per pixel. If this capability is not present, but +the projective divide needs to occur anyway, then it is performed on a +per-vertex basis by the Direct3D runtime. +D3DPTEXTURECAPS_SQUAREONLY +All textures must be square. +D3DPTEXTURECAPS_TEXREPEATNOTSCALEDBYSIZE +Texture indices are not scaled by the texture size prior to interpolation. +D3DPTEXTURECAPS_VOLUMEMAP +Device supports volume textures. +D3DPTEXTURECAPS_VOLUMEMAP_POW2 +Device requires that volume texture maps have dimensions specified +as powers of 2. +TextureFilterCaps +Texture-filtering capabilities for a Direct3DTexture object. Per-stage +filtering capabilities reflect which filtering modes are supported for texture +stages when performing multiple-texture blending with the +IDirect3DDevice8 interface. This member can be any combination of the +following per-stage texture-filtering flags. +D3DPTFILTERCAPS_MAGFAFLATCUBIC +Device supports per-stage flat cubic filtering for magnifying textures. +The flat cubic magnification filter is represented by the +D3DTEXF_FLATCUBIC member of the +D3DTEXTUREFILTERTYPE enumerated type. +D3DPTFILTERCAPS_MAGFANISOTROPIC +Device supports per-stage anisotropic filtering for magnifying textures. +The anisotropic magnification filter is represented by the +D3DTEXF_ANISOTROPIC member of the +D3DTEXTUREFILTERTYPE enumerated type. +D3DPTFILTERCAPS_MAGFGAUSSIANCUBIC +Device supports the per-stage Gaussian cubic filtering for magnifying +textures.

This ability corresponds to the +D3DTSS_ADDRESSU and D3DTSS_ADDRESSV render-state +values. +D3DPTADDRESSCAPS_MIRROR +Device can mirror textures to addresses. +D3DPTADDRESSCAPS_MIRRORONCE +Device can take the absolute value of the texture coordinate (thus, +mirroring around 0), and then clamp to the maximum value. +D3DPTADDRESSCAPS_WRAP +Device can wrap textures to addresses. +VolumeTextureAddressCaps +Texture-addressing capabilities for Direct3DVolumeTexture objects.

A texture coordinate is stored as a 32-bit +signed integer using 27 bits to store the integer part and 5 bits for the +floating point fraction. The maximum integer index, 227, is used to +determine the maximum texture coordinate, depending on how the +hardware does texture-coordinate scaling. +Some hardware reports the cap +D3DPTEXTURECAPS_TEXREPEATNOTSCALEDBYSIZE. For this case, +the device defers scaling texture coordinates by the texture size until after +interpolation and application of the texture address mode, so the number of times +a texture can be wrapped is given by the integer value in MaxTextureRepeat. +Less desirably, on some hardware +D3DPTEXTURECAPS_TEXREPEATNOTSCALEDBYSIZE is not set and +the device scales the texture coordinates by the texture size (using the highest +level of detail) prior to interpolation. This limits the number of times a texture +can be wrapped to MaxTextureRepeat / textureSize. +Example: +Given MaxTextureRepeat = 32k and texture size = 4 KB: +if the hardware sets D3DPTEXTURECAPS_TEXREPEATNOTSCALEDBYSIZE + # of times a texture can be wrapped = MaxTextureRepeat + // which is 32k in this example +else + # of times a texture can be wrapped = MaxTextureRepeat / textu + // which is 227/4k +MaxTextureAspectRatio +Maximum texture aspect ratio supported by the hardware, typically a power +of 2. +MaxAnisotropy +Maximum valid value for the D3DTSS_MAXANISOTROPY texture-stage +state. + +============================================================ +=== PAGE 271 === +============================================================ +MaxVertexW +Maximum W-based depth value that the device supports. +GuardBandLeft, GuardBandTop, GuardBandRight, and +GuardBandBottom +Screen space coordinates of the guard-band clipping region.

This interface provides +Microsoft® DirectX® with control of the object's lifetime and the ability to +retrieve other interfaces implemented by the object. IUnknown has three +methods. +AddRef increments the object's reference count by 1 when an interface or +another application binds itself to the object. +QueryInterface queries the object about the features that it supports by +requesting pointers to a specific interface. +Release decrements the object's reference count by 1. When the count +reaches 0, the object is deallocated. +The AddRef and Release methods maintain an object's reference count. For +example, if you create a Microsoft Direct3D® object, the object's reference +count is set to 1. Every time a function returns a pointer to an interface for that +object, the function must call AddRef through that pointer to increment the +reference count. Match each AddRef call with a call to Release. Before the +pointer can be destroyed, you must call Release through that pointer. After an +object's reference count reaches 0, the object is destroyed, and all interfaces to it +become invalid. +The QueryInterface method determines whether an object supports a specific +interface. If an object supports an interface, QueryInterface returns a pointer to +that interface. You then can use the methods of that interface to communicate +with the object. If QueryInterface successfully returns a pointer to an interface, +it implicitly calls AddRef to increment the reference count, so your application +must call Release to decrement the reference count before destroying the pointer +to the interface. +Requirements + Windows NT/2000/XP: Requires Windows NT 3.1 or later. + Windows 98/Me: Requires Windows 98 or later. + +============================================================ +=== PAGE 311 === +============================================================ + Header: Declared in Unknwn.h. + +============================================================ +=== PAGE 312 === +============================================================ + +Microsoft DirectX 8.1 (C++) + +============================================================ +=== PAGE 313 === +============================================================ +D3DXIMAGE_FILEFORMAT +Describes the supported image file formats. +typedef enum _D3DXIMAGE_FILEFORMAT +{ + D3DXIFF_BMP = 0, + D3DXIFF_JPG = 1, + D3DXIFF_TGA = 2, + D3DXIFF_PNG = 3, + D3DXIFF_DDS = 4, + D3DXIFF_PPM = 5, + D3DXIFF_DIB = 6, + D3DXIFF_FORCE_DWORD = 0x7fffffff +} D3DXIMAGE_FILEFORMAT; +Constants +D3DXIFF_BMP +Microsoft® Windows® bitmap file format. +D3DXIFF_JPG +Joint Photographic Experts Group compressed file. +D3DXIFF_TGA +Truevision Targa image file. +D3DXIFF_PNG +Portable Network Graphics file format. +D3DXIFF_DDS +Microsoft DirectDraw® surface file format. +D3DXIFF_PPM +Portable pixmap file format. +D3DXIFF_DIB +Windows bitmap file format. +D3DXIFF_FORCE_DWORD +Forces this enumeration to compile to 32 bits in size.

It provides basic, easy-to-build-upon functionally and +demonstrates the use of each component. +Along with the template, AppWizard includes the same C++ classes found in the +DirectX software development kit (SDK) common directory. These C++ classes +perform minimal wrapping of DirectX to get you up and running quickly. All the +DirectX SDK samples make use of these classes. For example, the Direct3D +samples use D3dapp.*, the DirectMusic samples use Dmutil.*, the DirectSound +samples use Dsutil.*, and the DirectPlay samples use Netconnect.*. +The AppWizard target audience is amateur C++ game developers, 3-D +hobbyists, and audio hobbyists (who do not need 3-D). + +============================================================ +=== PAGE 328 === +============================================================ +Running AppWizard +AppWizard is launched from Microsoft Visual Studio® 6.0 when you create a +new project. It is one of the project types available when you choose File, New, +then the Projects tab, as shown in the following example. +When you enter a project name and click OK, the wizard presents a series of +dialog boxes to allow you to configure the DirectX services that the application +will need. The number of dialog boxes generated by the wizard depend on which +DirectX technologies you select (Direct3D, DirectInput, and DirectPlay each +generate their own dialog boxes). The files included in the project depend on the +DirectX technologies selected, as well as the Microsoft Windows® technologies +selected—Microsoft Win32®, Microsoft Foundation Classes (MFC), and +Graphics Device Interface (GDI). You select these technologies on the first page +of the wizard, which is shown in the following example. +The wizard has three steps: Step 1 is the opening page, step 2 is the Direct3D +page, and step 3 is the DirectInput page. The DirectMusic and DirectSound +options do not generate additional pages but the DirectPlay Peer-to-Peer option +will generate an additional page. +The wizard uses one of four base templates, based on the options you select. +1. For an application that is not MFC-based and uses Direct3D, choose Single +document window and Direct3D. This is the standard case and is similar +to the application used in the dolphin sample. +2. For an application that is MFC-based and uses Direct3D, choose MFC +dialog based and Direct3D. The application will be similar to the MFC fog +sample. +3. For a Windows application that uses GDI but not MFC, choose Single +document window. This application can use CreateWindow and basic +GameLoop during idle time. + +============================================================ +=== PAGE 329 === +============================================================ +4. For an application that uses GDI and is MFC-based, choose MFC dialog +based. The application will be similar to the MFC AppWizard dialog +template. +The Direct3D, DirectInput, and DirectPlay check boxes each add another page +to the wizard. These pages are described in the following sections. +Direct3D Page +The following Direct3D page is shown immediately after the first page if you +selected the Direct3D check box in step 1. +The Direct3D page is step 2 because step 1 was the first page of the wizard. +The Direct3D exclusive options are: +1. Blank. No Direct3D object is created. +2. Triangle. Creates a simple object with two back-to-back triangles. +3. Teapot. Creates a complex object using D3DXCreateTeapot. +If Direct3D fonts is checked, the project includes D3dfont.cpp and D3dfont.h. +Otherwise, the project uses D3DXFont to display 3-D fonts. +If 3D meshes is checked, the project includes D3dfile.cpp and D3dfile.h. +DirectInput Page +The following DirectInput page is shown immediately after the Direct3D page +if you selected the DirectInput check box in step 1. +The DirectInput page is step 3. The options on this page are: +DirectInput action mapping. Uses Action Mapping to gather input data. +DirectInput keyboard device. Uses a simple keyboard device to gather +input data. + +============================================================ +=== PAGE 330 === +============================================================ +If you checked DirectInput in step 1, the project will include Diutil.cpp and +Diutil.cpp files. The DirectX SDK sample, Root\Samples\bin\Donut3D.exe, uses +these class files. +The application will use either Action Mapper or a keyboard device object to +record key state. If neither is checked, DirectInput will use WM_KEYDOWN +messages to record key state. +DirectMusic and DirectSound Check Boxes +These check boxes appear on page 1 of the wizard. They do no add pages to the +wizard. +If DirectMusic is checked, the project will include Dmutil.cpp and Dmutil.h. +The DirectMusic samples use these files. +If DirectSound is checked, the project will include Dsutil.cpp and Dsutil.h. The +DirectSound samples use these files to load and play sounds. +If both DirectMusic and DirectSound are checked, DirectMusic is used to load +and play the sounds, but Dsutil.* is still included in the project. +If either DirectMusic or DirectSound is checked, Bounce.wav is included in the +project. Pressing the A key will play the sound. +If neither DirectMusic nor DirectSound is checked, bounce.wav is not included +and the A key is not recorded, nor is the Help string displayed. +DirectPlay Page +The following DirectPlay page is shown immediately after the DirectInput page +if you selected the DirectPlay Peer-to-Peer check box in step 1. +The DirectPlay page is step 4, assuming that step 1 was the first page of the +wizard, step 2 was the Direct3D page, and step 3 was the DirectInput page. +If DirectVoice is checked, the project will include Netvoice.cpp and Netvoice.h. +The DirectPlay Voice samples use these files. + +============================================================ +=== PAGE 331 === +============================================================ +The project will integrate the NetConnect DirectPlay connection dialog boxes +into the application. When the NetConnect dialog boxes finish, an active +DirectPlay connection or failure results.

The vertex +data will contain (x,y,z) position and a diffuse color. The +D3DFVF_CUSTOMVERTEX macro is defined to match the vertex data. The +vertex data is declared in a global array of vertices (g_Vertices). The four +vertices are centered about the origin, and each vertex is given a different diffuse +color. +// Declare vertex data structure. +struct CUSTOMVERTEX +{ + FLOAT x, y, z; + DWORD diffuseColor; +}; +// Declare custom FVF macro. +#define D3DFVF_CUSTOMVERTEX (D3DFVF_XYZ|D3DFVF_DIFFUSE) +// Declare the vertex position and diffuse color data. +CUSTOMVERTEX g_Vertices[]= +{ + +============================================================ +=== PAGE 352 === +============================================================ + // x y z diffuse color + { -1.0f, -1.0f, 0.0f, 0xffff0000 }, // red - bottom right + { +1.0f, -1.0f, 0.0f, 0xff00ff00 }, // green - bottom left + { +1.0f, +1.0f, 0.0f, 0xff0000ff }, // blue - top left + { -1.0f, +1.0f, 0.0f, 0xffffff00 }, // red and green = yellow +}; +Step 2: Design the shader functionality +This shader applies a constant color to each vertex. The shader file +VertexShader.vsh follows: +vs.1.0 // version instruction +m4x4 oPos, v0, c0 // transform vertices by view/projection matrix +mov oD0, c4 // load constant color +This file contains three instructions. +The first instruction in a shader file must be the shader version declaration. This +instruction (vs) declares the vertex shader version, which is 1.0 in this case. +The second instruction (m4x4) transforms the object vertices using the +view/projection matrix. The matrix is loaded into four constant registers c0, c1, +c2, c3 (as shown below). +The third instruction (mov) copies the constant color in register c4 to the output +diffuse color register oD0. This results in coloring the output vertices. +Step 3: Check for vertex shader support +The device capability can be queried for vertex shader support before using a +vertex shader. +D3DCAPS8 caps; +m_pd3dDevice->GetDeviceCaps(∩ ); // initialize m_pd3dDevice bef +if( D3DSHADER_VERSION_MAJOR( caps.VertexShaderVersion ) < 1 ) +return E_FAIL; +The caps structure returns the functional capabilities of the hardware after +GetDeviceCaps is called. Use the D3DSHADER_VERSION_MAJOR macro +to test the supported version number. If the version number is less than 1.0, this +call will fail. The result of this method should be used to control whether or not + +============================================================ +=== PAGE 353 === +============================================================ +vertex shaders are invoked by an application. +Step 4: Declare the shader registers +The shader is created by declaring the shader registers and compiling the shader +file. Once created, Direct3D returns a shader handle, which is an integer number +that is used to identify the shader. +// Create the shader declaration. +DWORD dwDecl[] = +{ + D3DVSD_STREAM(0), + D3DVSD_REG(D3DVSDE_POSITION, D3DVSDT_FLOAT3), + D3DVSD_REG( D3DVSDE_DIFFUSE, D3DVSDT_D3DCOLOR ), + D3DVSD_END() +}; +The vertex declaration declares the mapping between input data streams and +vertex buffers. Multiple streams can be declared in the shader declaration, up to +the number specified in the MaxStreams cap. Vertex buffers are associated with +input streams using SetStreamSource as illustrated in step 5. +Step 5: Create the shader +The shader is assembled and created next. +// Create the vertex shader. +TCHAR strPath[512]; // location of the s +LPD3DXBUFFER pCode; // assembled shader +DXUtil_FindMediaFile( strPath, _T("VertexShader.vsh") ); +D3DXAssembleShaderFromFile( strPath, 0, NULL, &pCode;, NULL ); // a +m_pd3dDevice->CreateVertexShader( dwDecl, (DWORD*)pCode->GetBufferPo +pCode->Release(); +Once the shader file is located, D3DXAssembleShaderFromFile reads and +validates the shader instructions. CreateVertexShader takes the shader +declaration and the assembled instructions and creates the shader. It returns the +shader handle, which is used to render the output. +CreateVertexShader can be used to create programmable or fixed function +shaders. Programmable shaders are generated if a pointer to a shader declaration +is passed as the second parameter. Otherwise, a fixed function vertex shader is + +============================================================ +=== PAGE 354 === +============================================================ +generated if NULL is passed as the second parameter. +Step 6: Render the output pixels +Here is an example of the code that could be used in the render loop to render +the object, using the vertex shader. The render loop updates the vertex shader +constants as a result of changes in the 3-D scene and draws the output vertices +with a call to DrawPrimitive. +// Turn lighting off. This is included for clarity but is not requir +m_pd3dDevice->SetRenderState( D3DRS_LIGHTING, FALSE ); +// Update vertex shader constants from view projection matrix data. +D3DXMATRIX mat, matView, matProj; +D3DXMatrixMultiply( &mat;, &matView;, &matProj; ); +D3DXMatrixTranspose( &mat;, &mat; ); +m_pd3dDevice->SetVertexShaderConstant( 0, &mat;, 4 ); +// Declare and define the constant vertex color. +float color[4] = {0,1,0,0}; +m_pd3dDevice->SetVertexShaderConstant( 4, &color;, 1 ); +// Render the output. +m_pd3dDevice->SetStreamSource( 0, m_pQuadVB, sizeof(CUSTOMVERTEX) ); +m_pd3dDevice->SetVertexShader( m_hVertexShader ); +m_pd3dDevice->DrawPrimitive( D3DPT_TRIANGLEFAN, 0, 2 ); +Lighting is turned off just to make it clear that the vertex color is from the shader +only. This statement is optional in this example. +The view and projection matrixes contain camera position and orientation data. +Getting updated data and updating the shader constant registers is included in the +render loop because the scene might change between rendered frames. +As usual, DrawPrimitive renders the output data using the vertex data provided +from SetStreamSource. SetVertexShader is called to tell Direct3D to use the +vertex shader. The result of the vertex shader is shown in the following image. It +shows the constant color on the plane object. + +============================================================ +=== PAGE 355 === +============================================================ + +Microsoft DirectX 8.1 (shader versions 1.0, 1.1) + +============================================================ +=== PAGE 356 === +============================================================ +Shader2 - Apply vertex colors +This example applies the vertex color from the vertex data to the object.

You can fix this problem by adding Statement 2 +again. When you do this, the shader works again. +This is a simple example but it illustrates the usefulness of the tool.

The sample application also has an +Open button, which supports loading of a shader file so that you can load any +shader files you have already created. +Shader Debuggers +Some graphics chip companies provide a shader debugging tool on their Web +sites. Find these tools by searching the Web or by reading the article listed +below. You can attach a debugger to a program while it is running and use the +debugger to step through a shader. By setting breakpoints, you can step through +the shader code one line at a time and watch register state changes. For more +information about vertex shaders and debugging tips, see Using Vertex Shaders: +Part 1. +Texture Blending Debugging +Another sample application that is part of the software development kit (SDK) +installation is MFCTex. This Microsoft Foundation Classes (MFC) application is +a good way to learn how to perform multi-texture blending operations in the +fixed function pipeline. +Diagnostic Support +Another option for help with debugging DirectX problems is to use the DirectX +Diagnostic Viewer (DXDiag.exe) to create a dump of your machine. This is done +by running DxDiag.exe after your machine has crashed and sending the dump to +Microsoft, using either the Report button on the More Help tab or by sending it +to directx@microsoft.com.

It is the +fastest type of lighting but it produces the least realistic results. Microsoft® +Direct3D® contains a single global ambient light property that you can use +without creating any light.

The system considers two reflection types, diffuse and specular, +and uses a different formula to determine how much light is reflected for each. +After calculating the amounts of light reflected, Direct3D applies these new +values to the diffuse and specular reflectance properties of the current material. +The resulting color values are the diffuse and specular components that the +rasterizer uses to produce Gouraud shading and specular highlighting. +Diffuse lighting is described by the following equation. +Diffuse Lighting = sum[Vd*Ld*(N.Ldir)*Atten*Spot] +The parameters are defined in the following table. +Parameter +Default value +Type +Description +sum +N/A +N/A +Summation of each +light's diffuse +component. +Vd +(0,0,0,0) +D3DCOLORVALUE +Vertex diffuse color. +Ld +(0,0,0,0) +D3DCOLORVALUE +Light diffuse color. +N +N/A +D3DVECTOR +Vertex normal. +Ldir +(0,0,0,0) +D3DCOLORVALUE +Direction vector from +object vertex to the light. +Atten +(0,0,0,0) +D3DCOLORVALUE +Light attenuation. +Spot +(0,0,0,0) +D3DVECTOR +Characteristics of the +spotlight cone. +The value for Vd is one of three values: one of the two possible vertex colors in a +vertex declaration, or the material diffuse color.

This section explains how to +initialize the map. +1. Define Application Actions +The first step in implementing DirectInput action mapping is to determine what +input-driven actions in your application need to be mapped to device objects. For +actions that can be performed either by an axis or by a button, you must define +separate actions for both input types. It is recommended that you define button +actions for all important functions, in case the device does not have the +appropriate axes. +The following sample enumeration of action values might be defined by a car- +racing game. Axis actions begin with "eA" and button actions with "eB". +enum eGameActions +{ + eA_STEER, // Steering + eB_STEER_LEFT, // Steer left + eB_STEER_RIGHT, // Steer right + eA_ACCELERATE, // Change speed + eB_ACCELERATE, // Speed up + eB_DECELERATE, // Slow down + eA_BRAKE, // Brake + eB_BRAKE, // Brake + eB_UPSHIFT, // Shift to higher gear + eB_DOWNSHIFT, // Shift to lower gear + eB_CYCLEVIEW, // Cycle to next view + eB_COURSEVIEW, // Toggle course view + eB_DRIVERVIEW, // View from driver's seat + eB_BRAKEBIAS, // Brake bias + eA_VOLUME, // Sound volume + eB_MUTE // Toggle sound +}; + +============================================================ +=== PAGE 491 === +============================================================ +#define NUM_MY_ACTIONS 16 +In the example, actions are defined as enumerated values. However, they could +be other 32-bit data types, such as pointers to functions. When you retrieve +device data, you get whatever action value you have defined, and you can handle +it in any way you like. +2. Define the Genre +The next step is to decide what genre your application belongs to. A genre +defines a set of virtual controls. By selecting the proper genre, you can obtain the +best possible fit of virtual controls to application actions. Manufacturers who +choose to supply default mappings for their devices must support one or more of +the genres defined by DirectInput. See Action Mapping Constants for a list of +these genres. +For the game in the example, the obvious choice is the +DIVIRTUAL_DRIVING_RACE genre, which contains the following virtual +controls. +Priority 1 Controls +DIAXIS_DRIVINGR_STEER +DIAXIS_DRIVINGR_ACCELERATE +DIAXIS_DRIVINGR_BRAKE +DIBUTTON_DRIVINGR_SHIFTUP +DIBUTTON_DRIVINGR_SHIFTDOWN +DIBUTTON_DRIVINGR_VIEW +DIBUTTON_DRIVINGR_MENU +Priority 2 Controls +DIAXIS_DRIVINGR_ACCEL_AND_BRAKE +DIHATSWITCH_DRIVINGR_GLANCE +DIBUTTON_DRIVINGR_ACCELERATE_LINK +DIBUTTON_DRIVINGR_AIDS +DIBUTTON_DRIVINGR_BOOST +DIBUTTON_DRIVINGR_BRAKE +DIBUTTON_DRIVINGR_DASHBOARD + +============================================================ +=== PAGE 492 === +============================================================ +DIBUTTON_DRIVINGR_DEVICE +DIBUTTON_DRIVINGR_GLANCE_LEFT_LINK +DIBUTTON_DRIVINGR_GLANCE_RIGHT_LINK +DIBUTTON_DRIVINGR_MAP +DIBUTTON_DRIVINGR_PAUSE +DIBUTTON_DRIVINGR_PIT +DIBUTTON_DRIVINGR_STEER_LEFT_LINK +DIBUTTON_DRIVINGR_STEER_RIGHT_LINK +There is no difference in functionality between Priority 1 and Priority 2 controls. +Priority 1 controls are those most likely to be supported by device manufacturers +in their default mappings. However, there is no guarantee that any virtual control +will be supported by a device. +3. Assign Actions to Controls or Device Objects +The next step in creating the action map is to associate each application action +with one or more of the virtual controls defined for the genre. You do this by +declaring and initializing an array of DIACTION structures. Each structure in +the array specifies the action value, the virtual control to associate with it, and a +friendly name that describes the action. Leave other members as zero; they will +be filled in later by DirectInput. +You can also use elements of the DIACTION array to map actions to particular +keys or buttons on the keyboard or mouse or to channels on a Microsoft +DirectPlay® voice device. By doing so, you can take advantage of the simplified +input loop for all input, not just that from virtual controls. For example, suppose +you map the application-defined action eB_UPSHIFT to both the +DIBUTTON_DRIVINGR_SHIFTUP virtual control and to the Page Up key. +When retrieving data, you get back eB_UPSHIFT whether the input came from a +joystick button or the keyboard. +The following example declares an action map for the car-racing game. +DIACTION rgActions[]= +{ +//Genre-defined virtual axes + {eA_STEER, DIAXIS_DRIVINGR_STEER, 0, "Steer", }, + {eA_ACCELERATE, DIAXIS_DRIVINGR_ACCELERATE, 0, "Accelerate", }, + +============================================================ +=== PAGE 493 === +============================================================ + {eA_BRAKE, DIAXIS_DRIVINGR_BRAKE, 0, "Brake", }, +//Genre-defined virtual buttons + {eB_UPSHIFT, DIBUTTON_DRIVINGR_SHIFTUP, 0, "Upshift", }, + {eB_DOWNSHIFT, DIBUTTON_DRIVINGR_SHIFTDOWN, 0, "DownShift", }, + {eB_CYCLEVIEW, DIBUTTON_DRIVINGR_VIEW, 0, "Change View",}, +// Actions not defined in the genre that can be assigned to any +// button or axis + {eA_VOLUME, DIAXIS_ANY_1, 0, "Volume", } + {eB_MUTE, DIBUTTON_ANY(0), 0, "Toggle Sound",} +// Actions not defined in the genre that must be assigned to +// particular keys + {eB_DRIVERVIEW, DIKEYBOARD_1, 0, "Driver View",}, + {eB_COURSEVIEW, DIKEYBOARD_C, 0, "Course View",}, + {eB_BRAKEBIAS, DIKEYBOARD_B, 0, "Brake Bias", }, +// Actions mapped to keys as well as to virtual controls + {eB_UPSHIFT, DIKEYBOARD_PRIOR, 0, "Upshift", } + {eB_DOWNSHIFT, DIKEYBOARD_NEXT, 0, "Downshift", } + {eB_STEER_LEFT, DIKEYBOARD_LEFT, 0, "Steer Left", } + {eB_STEER_RIGHT, DIKEYBOARD_RIGHT, 0, "Steer Right",} + {eB_ACCELERATE, DIKEYBOARD_UP, 0, "Accelerate", } + {eB_DECELERATE, DIKEYBOARD_DOWN, 0, "Decelerate", } + {eB_BRAKE, DIKEYBOARD_END, 0, "Brake", } +// Actions mapped to buttons as well as to virtual controls and keys + {eB_UPSHIFT, DIMOUSE_BUTTON0, 0, "Upshift", }, + {eB_DOWNSHIFT, DIMOUSE_BUTTON1, 0, "Downshift", }, +}; +In the example, some actions are mapped to actual keys by using Keyboard +Mapping Constants. Similar mappings to the mouse buttons and axes can be +made by using Mouse Mapping Constants. +The DIACTION array is contained within a DIACTIONFORMAT structure +that also contains information about the genre, the application, and the desired +scaling of axis data. Use the same instance of this structure throughout the action +mapping process. Some members will not be used immediately, but you can fill +in the entire structure before the next step, Finding Matching Devices. + +============================================================ +=== PAGE 494 === +============================================================ + +Microsoft DirectX 8.1 (C++) +Finding Matching Devices +After you define the application actions and the virtual controls or device objects +to which these actions are to be mapped, the next step is to enumerate devices on +the system to find those that best support the desired virtual controls. +To do so, pass the DIACTIONFORMAT structure to +IDirectInput8::EnumDevicesBySemantics. This method works in much the +same way as IDirectInput8::EnumDevices and takes a similar callback +function. +Devices that have been configured by the user to match certain controls are +always enumerated first. For example, if a user has configured a wheel as the +primary steering device for driving games, then the wheel is enumerated first +whenever devices that support DIAXIS_DRIVINGR_STEER are requested, +taking precedence over other capable devices such as joysticks that have not +been configured by the user. Otherwise, the order in which available devices are +enumerated is determined by the degree to which they match the requested +controls. However, the order in which devices are enumerated by Microsoft® +DirectInput® is not guaranteed. +In the enumeration callback, you can retrieve the default action mapping for +each device, change any mappings you don't like, give the user an opportunity to +reconfigure the device, and apply the action map. These steps are covered in +Configuring the Action Map. Flags returned in the +DIEnumDevicesBySemanticsCallback will provide information about why a +particular device was enumerated. These flags will indicate whether a device has +been used recently, is newly installed, or will accept mappings of priority 1 or +priority 2 controls. + +============================================================ +=== PAGE 495 === +============================================================ + +Microsoft DirectX 8.1 (C++) +Configuring the Action Map +As each device is enumerated, you can obtain a pointer to it, retrieve the default +action map, make changes in the default map, and apply the final mappings. +1. Obtaining the Device +Obtain the IDirectInputDevice8 interface pointer for each enumerated device +from the lpdid parameter of the enumeration callback. See +DIEnumDevicesBySemanticsCallback. If you want to save the device +interface for use in your application, call AddRef on the pointer and assign it to +a global variable. +2. Obtaining the Default Action Map +To obtain the default action map for the device, call +IDirectInputDevice8::BuildActionMap. Microsoft® DirectInput® takes the +list of virtual controls specified in your DIACTIONFORMAT structure and +attempts to map these to physical device objects, returning the results in the +same structure. You should examine the dwHow member of each DIACTION +element to determine whether the control was successfully mapped. If it was, +you can also ascertain what criterion was used in choosing the object—for +example, configuration by the user or by the device manufacturer. +3. Making Changes to the Action Map +You now have the option of changing the default mappings, although it is not +recommended that you do so. After examining the dwSemantic member of the +DIACTION structure to determine which device object was mapped to an +action, you can change that value. For example, if an action is mapped to +DIJOFS_BUTTON9, but you want that action to be mapped to the trigger button +instead, change the value to DIJOFS_BUTTON0 before applying the action +map. + +============================================================ +=== PAGE 496 === +============================================================ +4. Applying the Action Map +When you are satisfied that the DIACTIONFORMAT structure contains +suitable mappings for the device, call IDirectInputDevice8::SetActionMap. +The value you assigned to the uAppData member of each DIACTION structure +now becomes bound to the control specified in the dwSemantic member, which +in turn is bound to a particular device object. +5. Mapping More than One Device +Repeat steps 1 though 4 for each device you want to use in your application. +Suppose you want to map actions to both a joystick and the keyboard. In the +racing-game example, the action defined in the game as eB_DRIVERVIEW was +mapped to a keyboard key in the following element of the DIACTION array. +{eB_DRIVERVIEW, DIKEYBOARD_1, "Driver View", }, +In that example, when BuildActionMap is called on any device that is not a +keyboard, the lHow member of the DIACTION structure for that element is set +to DIAH_UNMAPPED. Continue examining the lHow member as each device +in turn is enumerated, until a value other than DIAH_UNMAPPED is returned. +This indicates that the device being currently mapped is a keyboard and the +action has been successfully mapped to the requested key. +Even actions that have been successfully mapped can be mapped to another +device. In the example, eB_UPSHIFT is given two DIACTION structures, as +follows: +{eB_UPSHIFT, DIBUTTON_DRIVINGR_SHIFTUP, 0, "Upshift", }, +... +{eB_UPSHIFT, DIKEYBOARD_PRIOR, 0, "Upshift", }, +As devices are successively enumerated, the eB_UPSHIFT action is mapped to a +suitable button on one or more joysticks or other game controllers, and then +again to the keyboard. +6. Displaying the Configuration +To show the user how actions have been mapped to devices, pass the + +============================================================ +=== PAGE 497 === +============================================================ +DICD_DEFAULT flag to IDirectInput8::ConfigureDevices. The property +sheet for the device, containing a graphical representation of mappings, is +displayed in view-only mode as in the following diagram. For more information +on the mechanics of displaying the image, refer to the Using Action Mapping +tutorial. +If the device manufacturer has not provided a device image, the mapping will be +presented in text mode as in the following diagram. +Note Even if the cooperative level for the application is disabling the +Microsoft® Windows® logo key passively through an exclusive cooperative +level or actively through use of the DISCL_NOWINKEY flag, that key will be +active while the default action mapping UI is displayed. +For more information about this property sheet, see User Configuration of the +Device. + +============================================================ +=== PAGE 498 === +============================================================ + +Microsoft DirectX 8.1 (C++) +User Configuration of the Device +Microsoft® DirectInput® provides a property sheet that can be called from an +application, enabling the user to configure devices for the application and view +the current configuration. This property sheet can display various views of the +device as provided by the manufacturer. +To enable user configuration, pass a DICONFIGUREDEVICESPARAMS +structure containing a pointer to the DIACTIONFORMAT structure describing +the desired mapping, along with the DICD_EDIT flag, to the +IDirectInput8::ConfigureDevices method. Normally you would do this after +calling IDirectInputDevice8::BuildActionMap on all devices that will be used +in the application. +The following illustration shows a typical property sheet in edit mode. +If the device manufacturer has not provided a device image, the mapping will be +presented in text mode as in the following diagram. +Note Even if the cooperative level for the application is disabling the +Microsoft® Windows® logo key passively through an exclusive cooperative +level or actively through use of the DISCL_NOWINKEY flag, that key will be +active while the default action mapping UI is displayed. +The property page for a device lists the friendly names that were provided by +you in the lptszActionName member of each DIACTION structure. If you have +already called BuildActionMap for a device, the page also shows these names +as callouts on the image of the device, with lines pointing to the device objects to +which the actions have been mapped. +The user now has the opportunity to reassign game actions by first choosing a +control then choosing an action from the menu. When the user closes the + +============================================================ +=== PAGE 499 === +============================================================ +property sheet, the method returns and the modifications are stored in the +DIACTIONFORMAT structure that you passed in. You can now pass the same +structure to IDirectInputDevice8::SetActionMap in order to implement the +new mapping scheme. + +============================================================ +=== PAGE 500 === +============================================================ + +Microsoft DirectX 8.1 (C++) +Retrieving Action Data +You retrieve buffered data from action-mapped devices just as you would from +unmapped devices: by calling IDirectInputDevice8::GetDeviceData. However, +instead of identifying device objects by examining the dwOfs member of the +DIDEVICEOBJECTDATA structure, you obtain the action associated with the +object from the uAppData member. This is the same value you passed to the +device in the DIACTION structure. It can be a simple identifier or a pointer to a +function designed to handle the action. +Remember that an action can be associated with more than one device. You still +have to obtain data from both devices independently, but you can use the same +routine to handle the data regardless of where it comes from. +The following sample code, which might be part of the game loop in a driving +simulation, retrieves data from all devices in the g_lpIdiDevices array. This array +contains g_nDevices elements. +for (int iDevice = 0x0; iDevice < g_nDevices; iDevice++) +{ + DIDEVICEOBJECTDATA didod; + DWORD dwObjCount = 1; + // Poll the device for data. + g_lpDiDevices[iDevice]->Poll(); + + // Retrieve the data. + g_lpDiDevices[iDevice]->GetDeviceData( sizeof(didod), + &didod, + &dwObjCount, 0 ); + // Handle the actions regardless of what device returned them. + switch(didod.uAppData) + { + case eA_STEER: + SteerCar(didod.dwData); + break; + case eB_UPSHIFT + if (didod.dwData & 0x80) ShiftGears(UPSHIFT); + break; + +============================================================ +=== PAGE 501 === +============================================================ + . + . + . + default: + break; + } +} +Note Axis constants for specific genres, such as DIAXIS_DRIVINGR_STEER +or DIAXIS_SPACESIM_LATERAL, are used for absolute joystick data. The +action mapper attempts to map this virtual control to a device object that returns +absolute data. The data returned from that device should be processed +accordingly in the application. Device constants such as DIMOUSE_XAXIS, +however, are expected to return relative data. +When retrieving data, each potential source of data should be processed +separately to keep one device object from possibly overwriting the data from +another. For instance, the following DIACTION structures are used in an action +map to control direction. +{INPUT_LEFTRIGHT_ABS_AXIS, DIAXIS_SPACESIM_LATERAL, 0, _T("Turn"), +{INPUT_LEFTRIGHT_REL_AXIS, DIMOUSE_XAXIS, 0, _T("Turn"), +{INPUT_TURNLEFT, DIKEYBOARD_LEFT, 0, _T("Turn left"), +{INPUT_TURNRIGHT, DIKEYBOARD_RIGHT, 0, _T("Turn right"), +The application's input loop processes data from these actions in the following +case statement. +switch (adod[j].uAppData) +{ + case INPUT_LEFTRIGHT_ABS_AXIS: + g_dwAbsLR = adod[j].dwData + break; + case INPUT_LEFTRIGHT_REL_AXIS: + g_dwRelLR = adod[j].dwData; + break; + case INPUT_TURNLEFT: + g_bLeft = (adod[j].dwData != 0); + break; + case INPUT_TURNRIGHT: + g_bRight = (adod[j].dwData != 0) + break; +} + +============================================================ +=== PAGE 502 === +============================================================ +Note that each data source is assigned to a separate variable rather than all data +sources being assigned a generic "turn" variable. If they were to share a generic +variable, holding down the LEFT ARROW key and then moving the joystick +would cause the keyboard information to be lost. This is because the joystick +data would overwrite the variable. +In addition to individual variables, there are many ways to process the data. +Whatever method is used, care should be taken in the processing of data to avoid +unexpectedly lost information. + +============================================================ +=== PAGE 503 === +============================================================ + +Microsoft DirectX 8.1 (C++) +Maintaining Files During Development +During a development cycle, unused and out of date .ini files may accumulate +due to frequent action map changes, Microsoft® DirectX® reinstallations, +multiple users, and other normal development situations.

For this reason, it is good practice to occasionally delete any unused +.ini files. These files can be found in C:\Program Files\Common +Files\DirectX\DirectInput\User Maps. +Note The procedure suggested above is meant to be performed only manually +during a development cycle to ensure that the development environment is in a +cleaner state.

This document describes the Metal Shading Language (MSL), +which you will use to write a shader program, which is graphics and data-parallel compute code +that runs on the GPU. Shader programs run on different programmable units of the GPU. MSL is +a single, unified language that allows tighter integration between the graphics and compute +programs. Since MSL is C++-based, you will find it familiar and easy to use. +MSL works with the Metal framework, which manages the execution and optionally the +compilation of the Metal programs. Metal uses clang and LLVM so you get a compiler that +delivers optimized performance on the GPU. +1.2 Organization of This Specification +This document is organized into the following chapters: +• This chapter, “Introduction,” is an introduction to this document that covers the similarities +and differences between Metal and C++17. It also details the options for the Metal compiler, +including preprocessor directives, options for math intrinsics, and options for controlling +optimization. +• “Data Types” lists the Metal data types, including types that represent vectors, matrices, +buffers, textures, and samplers. It also discusses type alignment and type conversion. +• “Operators” lists the Metal operators. +• “Address Spaces” describes disjoint address spaces for allocating memory objects with +access restrictions. +• “Function and Variable Declarations” details how to declare functions and variables, with +optional attributes that specify restrictions. +• “Metal Standard Library” defines a collection of built-in Metal functions. +• “Numerical Compliance” describes requirements for representing floating-point numbers, +including accuracy in mathematical operations. +iOS and macOS support for features (functions, enumerations, types, attributes, or operators) +described in this document is available since Metal 1, unless otherwise indicated. +For the rest of this document, the abbreviation X.Y stands for “Metal version X.Y”; for example, +2.1 indicates Metal 2.1. Please note that though a feature is supported in MSL shading +language, it may not be supported on all GPUs. Please refer to the Metal Feature Set Tables at +developer.apple.com. +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 11 of 346 + +================================================================================ +=== PAGE 12 === +================================================================================ +1.3 New in Metal 4 +Metal 4 introduces the following new features: +• C++17 based (section 1.5) +• Sampler LOD bias, minimum and maximum reduction (section 2.10) +• Intersection Function Buffers (section 2.17.1, 5.1.6, 5.2.3.7 , 6.18.2, 6.18.4,and 6.18.8) +• Per-Vertex values (section 2.19) +• Tensors (section 2.21) +• User annotations (section 5.1.12) +• Texture atomics for cube and cube array textures (section 6.12.6 and 6.12.7) +• Pack and unpack of snorm10a2 (section 6.14) +• Indirect command buffer support for raster and depth stencil states (section 6.16.1) +• Metal Performance Primitives (section 7) +1.4 References +Metal +https://developer.apple.com/documentation/metal +Here is a link to the Metal documentation on apple.com: +1.5 Metal and C++17 +Starting in Metal 4, the Metal programming language is a C++17-based specification with +extensions and restrictions. Refer to the C++17 specification (also known as ISO/IEC +14882:2017) for a detailed description of the language grammar. Prior language versions of +Metal are a C++14-based specification with extensions and restrictions. +This section and its subsections describe the modifications and restrictions to the C++17 and +C++14 language supported in Metal. +For more about Metal preprocessing directives and compiler options, see section 1.6 of this +document. +1.5.1 Overloading +Metal supports overloading, as defined by section 13 of the C++17 and C++14 specification. +Metal extends the function overloading rules to include the address space attribute of an +argument. You cannot overload Metal graphics and kernel functions.

This option allows you to compile Metal code to enable or disable +features. You may use this option multiple times, and the preprocessor processes the +definitions in the order in which they appear. +-I dir +Add the directory dir to the search path of directories for header files. This option is +only available for the offline compiler. +1.6.2 Preprocessor Definitions +The Metal compiler sets a number of preprocessor definitions by default, including: +__METAL_VERSION__ // Set to the Metal language revision +__METAL_MACOS__ // Set if compiled with the macOS Metal language +__METAL_IOS__ // Set if compiled with the iOS Metal language +__METAL__ // Set if compiled with the unified Metal language +// Set with -std=metal3.0 or above +You can use definitions to conditionally apply shading language features that are only available +on later language version (see section 1.6.10 Compiler Options Controlling the Language +Version). +The version number is MajorMinorPatch. For example, for Metal 1.2, patch 0, +__METAL_VERSION__ is 120; for Metal 2.1, patch 1, __METAL_VERSION__ is 211. +To conditionally include code that uses features introduced in Metal 2, you can use the +preprocessor definition in code, as follows: +#if __METAL_VERSION__ >= 200 +// Code that requires features introduced in Metal 2. +#endif +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 14 of 346 + +================================================================================ +=== PAGE 15 === +================================================================================ +1.6.3 Math Intrinsics Compiler Options +The following section describes options to control compiler behavior regarding floating-point +arithmetic, trading off between speed and correctness. +For more about math functions, see section 6.5. For more about the relative errors of ordinary +and fast math functions, see section 8.4. +The options enable or disable the optimizations for floating-point arithmetic that may violate the +IEEE 754 standard. They also enable or disable the high precision variant of math functions for +single precision floating-point scalar and vector types. +The fast math optimizations for floating-point arithmetic include: +• No NaNs: Allow optimizations to assume the arguments and result are not NaN (not a +number). +• No INFs: Allow optimizations to assume the arguments and result are not positive or +negative infinity. +• No Signed Zeroes: Allow optimizations to treat the sign of a zero argument or result as +insignificant. +• Allow Reciprocal: Allow optimizations to use the reciprocal of an argument rather than +perform a division. +• Allow Reassociation: Allow algebraically equivalent transformations, such as reassociating +floating-point operations that may dramatically change the floating-point results. +• Allow Contract: Allow floating-point contraction across statements. For example, allow +fusing a multiple followed by an additional into a single fused-multiply-add. +Metal supports the following options beginning with Xcode 16 and Metal Developer Tools for +Windows 5 (SDK supporting iOS 18 or macOS 15). +-fmetal-math-fp32-functions= +This option sets the single-precision floating-point math functions described in section +6.5 to call either the fast or precise version. The default is fast. For Apple silicon, +starting with Apple GPU Family 4, the math functions honor INF and NaN. +-fmetal-math-mode= +This option sets how aggressive the compiler can be with floating-point optimizations. +The default is fast. +If you set the option to fast, it lets the compiler make aggressive, potentially lossy +assumptions about floating-point math. These include no NaNs, no INFs, no signed zeros, +allow reciprocal, allow reassociation, and FP contract to be fast. +If you set the option to relaxed, it lets the compiler make aggressive, potentially lossy +assumptions about floating-point math, but honors INFs and NaNs. These include no +signed zeros, allow reciprocal, allow reassociation, and FP contract to be fast. This +supports Apple silicon. +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 15 of 346 + +================================================================================ +=== PAGE 16 === +================================================================================ +If you set the option to safe, it disables unsafe floating-point optimizations by preventing +the compiler from making any transformations that might affect the results. This sets the +FP contract to on. +Metal supports the following legacy options: +-ffast-math +Equivalent to -fmetal-math-fp32-functions=fast and -fmetal-math- +mode=fast. +-fno-fast-math +Equivalent to -fmetal-math-fp32-functions=precise and -fmetal-math- +mode=safe. +When utilizing fast math in your program, it is important to understand that the compiler can +assume certain properties and make optimizations accordingly. For example, the use of fast +math asserts that the shader will never generate INF or NaN. If the program has an expression +X/Y, the compiler can assume Y is never zero as this could potentially result in positive/negative +infinite or NaN, depending on the value of X. If Y can be zero, you would have an undefined +program if compiled with fast math. +The #pragma section. +metal fp pragmas allow you to specify floating-point options for a source code +The following pragma has the same semantics to allow you to specify precise floating-point +semantics and floating-point exception behavior for a source code section. It can only appear in +file or namespace scope, within a language linkage specification, or at the start of a compound +statement (excluding comments). When using it within a compound statement, the pragma is +active within the scope of the compound statement: +#pragma METAL fp math_mode([relaxed | safe | fast]) +By default, the compiler allows floating-point contractions. For example, a*b+c may be +converted to a single fused-multiply-add. These contractions could lead to computation +differences if other expressions are not contracted. To disable allowing the compiler to +contractions, pass the following option: +-ffp-contract=off +The compiler also supports controlling contractions with the following pragma: +#pragma METAL fp contract([off | on | fast]) +Using off disables contractions, on allows contractions with statement, and fast allows +contractions across statements.

If +not set, [[invariant]] is ignored. +In previous versions of Metal, [[invariant]] was a best-effort analysis to mark which +operations need to be invariant and may fail in certain cases. This is replaced with a +conservative invariant model where the compiler marks operations that doesn’t go into an +invariant calculation. This will guarantee anything that is invariant calculation remains invariant. +This option may reduce performance as it may prevent certain optimizations to preserve +invariance. +1.6.5 Optimization Compiler Options +These options control the optimization level of the compiler: +-O2 +Optimize for performance (default). +-Os +Like -O2 with extra optimizations to reduce code size. +1.6.6 Maximum Total Threadgroup Size Option +All OS: Metal 3 and later support maximum total threadgroup size option. +This option specifies the number of threads (value) in a threadgroup for every function in the +translation unit: +-fmax-total-threads-per-threadgroup= +The attribute [[max_total_threads_per_threadgroup]] function attribute described in +section 5.1.3, section 5.1.7, and section 5.1.8 takes precedence over the compile option.

A vertex shader generates positions in clip-space coordinates. Metal divides +the x, y, and z values by w to convert clip-space coordinates into normalized device +coordinates. +Normalized device coordinates use a left-handed coordinate system (see Figure 1) and map to +positions in the viewport. These coordinates are independent of viewport size. The lower-left +corner of the viewport is at an (x,y) coordinate of (-1.0,-1.0) and the upper corner is at +(1.0,1.0). Positive-z values point away from the camera ("into the screen"). The visible +portion of the z coordinate is between 0.0 and 1.0. The Metal rendering pipeline clips +primitives to this box. +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 22 of 346 + +================================================================================ +=== PAGE 23 === +================================================================================ +Figure 1. Normalized device coordinate system +The rasterizer stage transforms normalized-device coordinates (NDC) into viewport coordinates +(see Figure 2). The (x,y) coordinates in this space are measured in pixels, with the origin in +the top-left corner of the viewport and positive values going to the right and down. You specify +viewports in this coordinate space, and the Metal maps NDC coordinates to the extents of the +viewport. +If you are using variable rasterization rate (see Section 6.15), then the viewport coordinate +system is a logical coordinate system independent of the render target’s physical layout. A rate +map determines the relationship between coordinates in this logical coordinate system +(sometimes called screen space) and pixels in the render targets (physical coordinates). +Figure 2. Viewport coordinate system +Texture coordinates use a similar coordinate system to viewport coordinates. Texture +coordinates can also be specified using normalized texture coordinates. For 2D textures, +normalized texture coordinates are values from 0.0 to 1.0 in both x and y directions, as seen +in Figure 3.

Applying a +single subscript to a matrix treats the matrix as an array of column vectors. Two subscripts +select a column and then a row. The top column is column 0. A second subscript then operates +on the resulting vector, as defined earlier for vectors. +float4x4 m; +// This sets the 2nd column to all 2.0. +m[1] = float4(2.0f); +// This sets the 1st element of the 1st column to 1.0. +m[0][0] = 1.0f; +// This sets the 4th element of the 3rd column to 3.0. +m[2][3] = 3.0f; +Access floatnxm and halfnxm matrices as an array of n floatm or n halfm entries. +Accessing a component outside the bounds of a matrix with a nonconstant expression results in +undefined behavior. Accessing a matrix component that is outside the bounds of the matrix +with a constant expression generates a compile-time error. +2.3.2 Matrix Constructors +Use constructors to create matrices from a set of scalars, vectors, or matrices. The parameter +signature determines how to construct and initialize a matrix. For example, if you initialize a +matrix with only a single scalar parameter, the result is a matrix that contains that scalar for all +components of the matrix’s diagonal, with the remaining components initialized to 0.0. For +example, a call to: +float4x4(fval); +Where fval is a scalar floating-point value constructs a matrix with these initial contents: +fval 0.0 0.0 0.0 +0.0 fval 0.0 0.0 +0.0 0.0 fval 0.0 +0.0 0.0 0.0 fval +You can also construct a matrix from another matrix that has the same number of rows and +columns.

The matrix +constructor needs to have just enough specified values in its arguments to initialize every +component in the constructed matrix object. Providing more arguments than necessary results +in an error. Under-initializing a matrix constructor results in a compile-time error. +You can also construct a matrix of type T with n columns and m rows from n vectors of type T +with m components. The following examples are legal constructors: +float2x2(float2, float2); +float3x3(float3, float3, float3); +float3x2(float2, float2, float2); +In Metal 2 and later, a matrix of type T with n columns and m rows can also be constructed from +n * m scalars of type T.

You can’t +construct a matrix from combinations of vectors and scalars. +// Not supported. +float2x3(float2 a, float b, float2 c, float d); +2.4 SIMD-group Matrix Data Types +All OS: Metal 2.3 and later support SIMD-group matrix types. +Metal supports a matrix type simdgroup_matrix defined in +. Operations on SIMD-group matrices are executed +cooperatively by threads in the SIMD-group.

You may also apply the alignas specifier to the declaration of a variable or a data +member of a structure or class. You may also apply it to the declaration of a structure, class, or +enumeration type. +The Metal compiler is responsible for aligning data items to the appropriate alignment as +required by the data type. For arguments to a graphics or kernel function declared to be a +pointer to a data type, the Metal compiler assumes that the object referenced by the pointer is +always appropriately aligned as required by the data type. +2.6 Atomic Data Types +Objects of atomic types are free from data races. If one thread writes to an atomic object while +another thread reads from it, the behavior is well-defined. +Metal supports atomic, where T can be int, uint, bool, or ulong for all OSes that +support Metal 2.4 and later, or T can be float for all OSes that support Metal 3 and later. +Metal provides these type aliases for atomic types: +atomic_int A type of alias of atomic for OSes that support Metal 1 and later. +atomic_uint A type of alias of atomic for OSes that support Metal 1 and later. +atomic_bool A type of alias of atomic for OSes that support Metal 2.4 and later. +atomic_ulong A type of alias of atomic for OSes that support Metal 2.4 and later. +atomic_float A type of alias of atomic for OSes that support Metal 3 and later. +Metal atomic functions (as described in section 6.15) can only use Metal atomic data types. +These atomic functions are a subset of the C++17 atomic and synchronization functions. +2.7 Pixel Data Types +iOS: Metal 2 and later support pixel data types. +macOS: Metal 2.3 and later support pixel data types. +The Metal pixel data type is a templated type that describes the pixel format type and its +corresponding ALU type.

For texture types +(except depth texture types), T can be half, float, short, ushort, int, or uint. For depth +texture types, T must be float. +If T is int or short, the data associated with the texture must use a signed integer format. If T +is uint or ushort, the data associated with the texture must use an unsigned integer format. +If T is half, the data associated with the texture must either be a normalized (signed or +unsigned integer) or half-precision format. If T is float, the data associated with the texture +must either be a normalized (signed or unsigned integer), half or single-precision format. +These access attributes describe support for accessing a texture: +• sample — A graphics or kernel function can sample the texture object. sample implies the +ability to read from a texture with and without a sampler. +• read — Without a sampler, a graphics or kernel function can only read the texture object. +• write — A graphics or kernel function can write to the texture object. +• read_write — A graphics or kernel function can read and write to the texture object. +All OS: Metal 1.2 and later support read_write access.

Similar type conversion can +be achieved without texture buffers by either: +• Reading the pixel data (just like any other array) from a texture object and performing the +pixel transformation to the desired format. +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 44 of 346 + +================================================================================ +=== PAGE 45 === +================================================================================ +• Wrapping a texture object around the data of a buffer object, then accessing the shared +buffer data via the texture. This wrapping technique provides the pixel conversion, but +requires an extra processing step, and the size of the texture is limited. +The following template defines the opaque type texture_buffer, which you can use like any +texture: +texture_buffer +access can be one of read, write, or read_write. +T specifies the type of a component returned when reading from a texture buffer or the type of +component specified when writing to a texture buffer. For a texture buffer, T can be one of +half, float, short, ushort, int, or uint. +For a format without an alpha channel (such as R, RG, or RGB), an out-of-bounds read returns +(0, 0, 0, 1). For a format with alpha (such as RGBA), an out-of-bounds read returns (0, +0, 0, 0). For some devices, an out-of-bounds read might have a performance penalty. +Metal ignores an out-of-bounds write. +A texture buffer can support more texture data than a generic 1D texture, which has is a +maximum width of 16384. However, you cannot sample a texture buffer. +A texture buffer also converts data, delivering it in the requested texture format, regardless of +the source’s format. When creating a texture buffer, you can specify the format of the data in +the buffer (for example, RGBA8Unorm), and later the shader function can read it as a +converted type (such as float4). As a result, a single pipeline state object can access data +stored in different pixel formats without recompilation. +A texture buffer, like a texture type, can be declared as the type of a local variable to a shader +function. For information about arrays of texture buffers, see section 2.12.1. For more about +texture buffer, see section 6.12.16. +2.10 Samplers +The sampler type identifies how to sample a texture. The Metal API allows you to create a +sampler object and pass it in an argument to a graphics or kernel function. You can describe a +sampler object in the program source instead of in the API. For these cases, you can only +specify a subset of the sampler state: the addressing mode, filter mode, normalized +coordinates, and comparison function. +Table 2.7 lists the supported sampler state enumerations and their associated values (and +defaults).

You can also declare an array of samplers in program scope. Unless used in +an argument buffer (see section 2.13), you cannot declare an array type (an array of +textures, texture buffers, or samplers) in a structure. +MSL also adds support for array_ref. An array_ref represents an immutable array +of size() elements of type T. T must be a sampler type or a supported texture type, including +texture buffers. The storage for the array is not owned by the array_ref object. Implicit +conversions are provided from types with contiguous iterators like metal::array. A common +use for array_ref is to pass an array of textures as an argument to functions so they can +accept a variety of array types. +The array_ref type cannot be passed as an argument to graphics and kernel functions. +However, the array_ref type can be passed as an argument to user functions. The +array_ref type cannot be declared as local variables inside functions. +The member functions listed in sections 2.12.1.1 to 2.12.1.3 are available for the array of +textures, array of samplers, and the array_ref types. +2.12.1.1 Array Element Access with its Operator +Elements of an array of textures, texture buffers, or samplers can be accessed using the [] +operator: +reference operator[] (size_t pos); +Elements of an array of textures, texture buffers, or samplers, or a templated type +array_ref can be accessed using the following variant of the [] operator: +constexpr const_reference operator[] (size_t pos) const; +2.12.1.2 Array Capacity +size() returns the number of elements in an array of textures, texture buffers, or samplers: +constexpr size_t size(); +constexpr size_t size() const; +Example: +kernel void +my_kernel(const array, 10> src [[texture(0)]], +texture2d dst [[texture(10)]], +…) +{ +for (int i=0; i +constexpr array_ref(const T(&a)[N]); +template +constexpr array_ref make_array_ref(const T * array, size_t +length) +template +constexpr array_ref make_array_ref(const T(&a)[N]) +Examples of constructing arrays: +float4 foo(array_ref> src) +{ +float4 clr(0.0f); +for (int i=0; i, 10> src [[texture(0)]], +texture2d dst [[texture(10)]], +…) +{ +float4 clr = foo(src); +… +} +kernel void +my_kernel_B(const array, 20> src [[texture(0)]], +texture2d dst [[texture(10)]], +…) +{ +float4 clr = foo(src); +… +} +Below is an example of an array of samplers declared in program scope: +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 52 of 346 + +================================================================================ +=== PAGE 53 === +================================================================================ +constexpr array = { sampler(address::clamp_to_zero), +sampler(coord::pixel) }; +2.12.2 Structures of Buffers, Textures, and Samplers +Arguments to a graphics, kernel, visible, or user function can be a structure or a nested +structure with members that are buffers, textures, or samplers only.

However, argument buffers cannot contain unions. The following +example specifies an argument buffer structure called Foo for a function: +struct Foo { +texture2d a; +depth2d b; +sampler c; +texture2d d; +device float4* e; +texture2d f; +texture_buffer g; +int h; +}; +kernel void +my_kernel(constant Foo & f [[buffer(0)]]) +{…} +Arrays of textures and samplers can be declared using the existing array templated +type. Arrays of all other legal buffer types can also be declared using C-style array syntax. +Members of argument buffers can be assigned a generic [[id(n)]] attribute, where n is a +32-bit unsigned integer that can be used to identify the buffer element from the Metal API. +Argument buffers can be distinguished from regular buffers if they contain buffers, textures, +samplers, or any element with the [[id]] attribute. +The same index may not be assigned to more than one member of an argument buffer. +Manually assigned indices do not need to be contiguous, but they must be monotonically +increasing. In the following example, index 0 is automatically assigned to foo1. The +[[id(n)]] attribute specifies the index offsets for the t1 and t2 structure members. Since +foo2 has no specified index, it is automatically assigned the next index, 4, which is determined +by adding 1 to the maximum ID used by the previous structure member. +struct Foo { +texture2d t1 [[id(1)]]; +texture2d t2 [[id(3)]]; +}; +struct Bar { +Foo foo1; // foo1 assigned idx 0, t1 and t2 assigned idx 1 and 3 +Foo foo2; // foo2 assigned idx 4, t1 and t2 assigned idx 5 and 7 +}; +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 54 of 346 + +================================================================================ +=== PAGE 55 === +================================================================================ +If you omit the [[id]] attribute, Metal automatically assigns an ID according to the following +rules: +1. Metal assigns IDs to structure members in order, by adding 1 to the maximum ID of the +previous structure member. In the example below, the indices are not provided, so +indices 0 and 1 are automatically assigned. +struct MaterialTexture { +texture2d tex; // Assigned index 0 +float4 uvScaleOffset; // Assigned index 1 +2. }; +Metal assigns IDs to array elements in order, by adding 1 to the maximum ID of the +previous array element. In the example below, indices 1-3 are automatically assigned to +the three array elements of texs1. Indices 4-5 are automatically assigned to the fields +in materials[0], indices 6-7 to materials[1], and indices 8-9 to materials[2]. +The [[id(20)]] attribute starts by assigning index 20 to constants. +struct Material { +float4 diffuse; // Assigned index 0 +array, 3> texs1; // Assigned indices 1-3 +MaterialTexture materials[3]; // Assigned indices 4-9 +int constants [[id(20)]] [4]; // Assigned indices 20-23 +3. }; +If a structure member or array element E is itself a structure or array, Metal assigns +indices to its structure members or array elements according to rules 1 and 2 +recursively, starting from the ID assigned to E. In the following example, index 4 is +explicitly provided for the nested structure called normal, so its elements (previously +defined as tex and uvScaleOffset) are assigned IDs 4 and 5, respectively. The +elements of the nested structure called specular are assigned IDs 6 and 7 by adding +one to the maximum ID (5) used by the previous member. +struct Material { +MaterialTexture diffuse; // Assigned indices 0, 1 +MaterialTexture normal [[id(4)]]; // Assigned indices 4, 5 +MaterialTexture specular; // Assigned indices 6, 7 +} +4. Metal assigns IDs to top-level argument buffer arguments starting from 0, according to +the previous three rules. +2.13.1 Tier 2 Hardware Support for Argument Buffers +With Tier 2 hardware, argument buffers have the following additional capabilities that are not +available with Tier 1 hardware. +You can access argument buffers through pointer indexing.

The variable i is nonuniform; that is, it can have a different value for threads +executing the graphics or kernel function for a draw or dispatch call, as shown in the example +below. Therefore, the texture sampling hardware must handle a sample request that can refer +to different textures for threads executing the graphics or kernel function for a draw or dispatch +call. +kernel void +my_kernel(array, 10> texInput, +array, 10> texOutput, +sampler s, +…, +uint2 gid [[thread_position_in_grid]]) +{ +int i = …; +…; +float4 color = texInput[i].sample(s, float2(gid)); +texOutput[i].write(color, float2(gid)); +} +If the variable i has the same value for all threads (is uniform) executing the graphics or kernel +function of a draw or dispatch call and if this information was communicated to the hardware, +then the texture sampling hardware can apply appropriate optimizations. A similar argument +can be made for texture writes, where a variable computed at runtime is used as an index into +an array of textures or to index into one or more buffers. +To indicate that this variable is uniform for all threads executing the graphics or kernel function +of a draw or dispatch call, MSL adds a new template class called uniform (available in the +header metal_uniform) that can be for declaring variables inside a graphics or kernel +function. This template class can only be instantiated with arithmetic types (such as Boolean, +integer, and floating-point) and vector types. +The code below is a modified version of the previous example, where the variable i is declared +as a uniform type: +kernel void +my_kernel(array, 10> texInput, +array, 10> texOutput, +sampler s, +…, +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 57 of 346 + +================================================================================ +=== PAGE 58 === +================================================================================ +{ +uint2 gid [[thread_position_in_grid]]) +uniform i = …; +float4 color = texInput[i].sample(s, float2(gid)); +…; +texOutput[i].write(color, float2(gid)); +} +2.14.2 Behavior of the Uniform Type +If a variable is of the uniform type, and the variable does not have the same value for all +threads executing the kernel or graphics function, then the behavior is undefined. +Uniform variables implicitly type convert to nonuniform types. Assigning the result of an +expression computed using uniform variables to a uniform variable is legal but assigning a +nonuniform variable to a uniform variable results in a compile-time error. In the following +example, the multiplication legally converts the uniform variable x into nonuniform product z. +However, assigning the nonuniform variable z to the uniform variable b results in a compile- +time error. +uniform x = …; +int y = …; +int z = x*y; // Here, x converts to a nonuniform for a multiply. +uniform b = z; // Illegal; causes a compile-time error. +To declare an array of uniform elements: +uniform bar[10]; // Elements stored in bar array are uniform. +The uniform type is legal for both parameters and the return type of a function. For example: +uniform foo(…); // foo returns a uniform integer value. +int bar(uniform a, …); +It is legal to declare a pointer to a uniform type, but not legal to declare a uniform pointer. For +example: +device uniform *ptr; // Values pointed to by ptr are uniform. +uniform ptr; // Illegal; causes a compile-time error. +The results of expressions that combine uniform with nonuniform variables are nonuniform. If +the nonuniform result is assigned to a uniform variable, as in the example below, the behavior is +undefined.

Code for control flow based on uniform +quantities should be more efficient than code for control flow based on nonuniform quantities. +2.15 Visible Function Table +All OS: Metal 2.3 and later support visible function table. +Defined in the header , you use the +visible_function_table type to represent a table of function pointers to visible functions +(see section 5.1.4) that the system stores in device memory. In Metal 2.3 and later, you can use +it in a compute (kernel) function. In Metal 2.4 and later, you can use it in fragment, vertex, and +tile functions. It is an opaque type, and you can’t modify the content of the table from the GPU. +You can use a visible_function_table type in an argument buffer or directly pass it to a +qualified function using a buffer binding point. +To declare a visible_function_table type with a template parameter T where +T is the signature of the function stored in the table, use the following template function. +visible_function_table +The following example shows how to declare a table that is compatible with a function whose +definition is “[[visible]] int func(float f)”: +visible_function_table functions; +To get a visible function pointer from the table, use the [] operator: +using fnptr = T (*)(…) [[visible]] +fnptr operator[](uint index) const; +size() returns the number of function pointer entries in the table: +uint size() const +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 59 of 346 + +================================================================================ +=== PAGE 60 === +================================================================================ +empty() returns true if the table is empty: +bool empty() const +The following function can be used to determine if a table is a null visible_function_table. +A null visible_function_table is a table that is not pointing to anything. +bool is_null_visible_function_table(visible_function_table); +The following example shows how the table can be passed in a buffer: +using TFuncSig = void(float, int); +kernel void F(uint tid [[thread_position_in_grid]], +device float* buf [[buffer(0)]], +visible_function_table table [[buffer(1)]]) +{ +uint tsize = table.size(); +table[tid % tsize](buf[tid], tid); +} +2.16 Function Groups Attribute +All OS: Metal 2.3 and later support [[function_groups]]. +The optional [[function_groups]] attribute can be used to indicate the possible groups of +functions being called from an indirect call through a function pointer or +visible_function_table. This is a compiler hint to enable the compiler to optimize the call +site. The groups of functions are specified as string literal arguments of the attribute. This +attribute can be applied in three different contexts: +• Variable declarations with an initializer expression — It affects all indirect call +expressions in the initializer expressions. +• Expression statements — It affects all the indirect call expressions of the given +expression. +• Return statements — It affects all the indirect call expressions of the return value +expression. +The following examples show how [[function_groups]] can be used: +float h(visible_function_table table, +float (*fnptr[3])(float)) +{ +// An indirect call to table[0] is restricted to “group1”. +[[function_groups("group1")]] float x = table[0](1.0f); +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 60 of 346 + +================================================================================ +=== PAGE 61 === +================================================================================ +// An indirect call to `fnptr[0]` can call any function. +x += fnptr[0](2.0f); +// An indirect call to `fnptr[1]` is restricted to +// "group2"+"group3". +[[function_groups("group2", "group3")]] return x + fnptr[1](3.0f); +} +2.17 Ray-Tracing Types +All OS: Metal 2.3.and later support ray-tracing types. +The header defines these types in the namespace +metal::raytracing.

In Metal 3.1 and later, ray tracing supports +curves and multilevel instancing. +2.17.1 Ray-Tracing Intersection Tags +All OS: Metal 2.3.and later support ray-tracing intersection tags. +The header defines intersection +_tags in the namespace +metal::raytracing. They are listed in Table 2.9 and are used in ray tracing when defining: +• intersection functions ([[intersection]] section 5.1.6) +• intersection function tables (intersection_function_table section 2.17.3) +• intersection results (intersection_result section 2.17.4) +• intersector types and associated functions (intersector section 6.18.2) +• acceleration structure types (acceleration_structure section 2.17.7 and 6.18.1) +• intersection queries (intersection_query section 6.18.5). +The tags are used to configure the ray tracing process and control the behavior and semantics +of the different types and tables. The tags identify the type of accelerator structure being +intersected, the built-in parameters available for intersection functions, the type of intersection +function in an intersection function table, the methods available on intersector type or +intersection query object, and the data returned in an intersection result type. +The intersection_tags must match in tag type and order between related uses of +intersection_function_table, intersection_result , intersector, and +intersection_query, or the compiler will generate an error. The acceleration structure type +being intersected must match the ordering of instancing, primitive_motion, and +instance_motion tags if they are present on the other ray tracing types used to intersect the +acceleration structure. When calling intersection functions in an intersection function +table, you need to ensure they use the same ordered set of tags, or else the result is undefined. +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 61 of 346 + +================================================================================ +=== PAGE 62 === +================================================================================ +Table 2.9.

If the source type is a +scalar or vector Boolean, the value false is converted to zero, and the value true is +converted to one. +Metal adds an as_type operator to allow any scalar or vector data type (that is not +a pointer) to be reinterpreted as another scalar or vector data type of the same size. The bits in +the operand are returned directly without modification as the new type. The usual type +promotion for function arguments is not performed. +For example, as_type(0x3f800000) returns 1.0f, which is the value of the bit +pattern 0x3f800000 if viewed as an IEEE-754 single precision value. +Using the as_type operator to reinterpret data to a type with a different number +of bytes results in an error. +Examples of legal and illegal type conversions: +float f = 1.0f; +// Legal.

Result and operand have different sizes +float4 g = as_type(f); +float4 f; +// Legal. g.xyz has same values as f.xyz. +float3 g = as_type(f); +2.23 Implicit Type Conversions +Implicit conversions between scalar built-in types (except void) are supported. When an implicit +conversion is done, it is not just a re-interpretation of the expression's value but a conversion of +that value to an equivalent value in the new type. For example, the integer value 5 is converted +to the floating-point value 5.0. A bfloat is an extended floating-point type that only allows +implicit conversion to a type of greater floating-point rank. While bfloat can be implicitly +converted to float, it cannot be implicitly converted to half, and neither float nor half can be +implicitly converted to bfloat. +All vector types are considered to have a higher conversion rank than scalar types. Implicit +conversions from a vector type to another vector or scalar type are not permitted and a +compilation error results. For example, the following attempt to convert from a 4-component +integer vector to a 4-component floating-point vector fails. +int4 i; +float4 f = i; // Results in a compile error. +Implicit conversions from scalar-to-vector types are supported. The scalar value is replicated in +each element of the vector. The scalar may also be subject to the usual arithmetic conversion to +the element type used by the vector. +For example: +float4 f = 2.0f; // f = (2.0f, 2.0f, 2.0f, 2.0f) +Implicit conversions from scalar-to-matrix types and vector-to-matrix types are not supported +and a compilation error results. Implicit conversions from a matrix type to another matrix, vector +or scalar type are not permitted and a compilation error results. +Implicit conversions for pointer types follow the rules described in the C++17 Specification. +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 93 of 346 + +================================================================================ +=== PAGE 94 === +================================================================================ +3 Operators +All OS: Metal 1 and later support scalar, vector, and matrix operators. +For indirect command buffers, the assignment operator (=) does not copy the contents of a +command. For more about copying commands in indirect command buffers, see section 6.16.3. +3.1 Scalar and Vector Operators +This section lists both binary and unary operators and describes their actions on scalar and +vector operands. +1. The arithmetic binary operators, add (+), subtract (–), multiply (*) and divide (/), act +upon scalar and vector, integer, and floating-point data type operands. Following the +usual arithmetic conversions, all arithmetic operators return a result of the same built-in +type (integer or floating-point) as the type of the operands. After conversion, the +following cases are valid: +2. • If the two operands of the arithmetic binary operator are scalars, the result of the +operation is a scalar. +• If one operand is a scalar, and the other operand is a vector, +• The scalar converts to the element type that the vector operand uses. +• The scalar type then widens to a vector that has the same number of +components as the vector operand. +• Metal performs the operation componentwise, which results in a same size +vector. +• If the two operands are vectors of the same size, Metal performs the operation +componentwise, which results in a same size vector. +Division on integer types that result in a value that lies outside of the range bounded by +the maximum and minimum representable values of the integer type, such as +TYPE_MIN/-1 for signed integer types or division by zero, does not cause an exception +but results in an unspecified value. Division by zero for floating-point types results in ±∞ +or NaN, as prescribed by IEEE-754. (For more about the numerical accuracy of floating- +point operations, see section 8.) +Because bfloat and half are not implicitly convertible to each other, the operators do +not support mixing bfloat and half. +The modulus operator (%) acts upon scalar and vector integer data type operands. The +modulus operator returns a result of the same built-in type as the type of the operands, +after the usual arithmetic conversions. The following cases are valid: +• If the two operands of the modulus operator are scalars, the result of the operation is +a scalar. +• If one operand is a scalar, and the other is a vector: +• The scalar converts to the element type of the vector operand. +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 94 of 346 + +================================================================================ +=== PAGE 95 === +================================================================================ +3. 4. 5. 6. • The scalar type then widens to a vector that has the same number of +components as the vector operand. +• Metal performs the operation componentwise, which results in a same-size +vector. +• If the two operands are vectors of the same size, Metal performs the operation +componentwise, which results in a same-size vector. +For any component computed with a second operand that is zero, the modulus operator +result is undefined. If one or both operands are negative, the results are undefined. +Results for other components with nonzero operands remain defined. +If both operands are nonnegative, the remainder is nonnegative. +The arithmetic unary operators (+ and –) act upon scalar and vector, integer, and +floating-point type operands. +The arithmetic post- and pre-increment and decrement operators (–– and ++) have +scalar and vector integer type operands. All unary operators work componentwise on +their operands. The result is the same type as the operand. For post- and pre-increment +and decrement, the expression needs to be assignable to an lvalue. Pre-increment +and predecrement add or subtract 1 to the contents of the expression on which they +operate, and the value of the pre-increment or predecrement expression is the resulting +value of that modification. Post-increment and post-decrement expressions add or +subtract 1 to the contents of the expression on which they operate, but the resulting +expression has the expression’s value before execution of the post-increment or post- +decrement. +The relational operators [greater-than (>), less-than (<), greater-than or equal to (>=), +and less-than or equal to (<=)] act upon scalar and vector, integer, and floating-point +type operands. The result is a Boolean (bool type) scalar or vector. After converting the +operand type, the following cases are valid: +• If the two operands of the relational operator are scalars, the result of the operation +is a Boolean. +• If one operand is a scalar, and the other is a vector: +• The scalar converts to the element type of the vector operand. +• The scalar type then widens to a vector that has the same number of +components as the vector operand. +• Metal performs the operation componentwise, which results in a Boolean vector. +• If the two operands are vectors of the same size, Metal performs the operation +componentwise, which results in a same-size Boolean vector. +If either argument is a NaN, the relational operator returns false. To test a relational +operation on any or all elements of a vector, use the any and all built-in functions in +the context of an if(…) statement. (For more about any and all functions, see +section 6.4.) +The equality operators, equal (==) and not equal (!=), act upon scalar and vector, +integer and floating-point type operands. All equality operators result in a Boolean scalar +or vector. After converting the operand type, the following cases are valid: +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 95 of 346 + +================================================================================ +=== PAGE 96 === +================================================================================ +• If the two operands of the equality operator are scalars, the result of the operation is +a Boolean. +• If one operand is a scalar, and the other is a vector: +• The scalar converts to the element type of the vector operand. +• The scalar type then widens to a vector that has the same number of +components as the vector operand. +• Metal performs the operation componentwise, which results in a Boolean vector. +• If the two operands are vectors of the same size, Metal performs the operation +componentwise, which results in a same-size Boolean vector. +7. All other cases of implicit conversions are illegal. If one or both arguments is NaN, the +equality operator equal (==) returns false. If one or both arguments is NaN, the +equality operator not equal (!=) returns true. +The bitwise operators [and (&), or (|), exclusive or (^), not (~)] can act upon all scalar +and vector built-in type operands, except the built-in scalar and vector floating-point +types. +• For built-in vector types, Metal applies the bitwise operators componentwise. +• If one operand is a scalar and the other is a vector, +• The scalar converts to the element type used by the vector operand. +• The scalar type then widens to a vector that has the same number of +components as the vector operand. +• Metal performs the bitwise operation componentwise resulting in a same-size +vector. +8. 9. The logical operators [and (&&), or (||)] act upon two operands that are Boolean +expressions. The result is a scalar or vector Boolean. +The logical unary operator not (!) acts upon one operand that is a Boolean expression. +The result is a scalar or vector Boolean. +10. The ternary selection operator (?:) acts upon three operands that are expressions +(exp1?exp2:exp3). This operator evaluates the first expression exp1, which must +result in a scalar Boolean. If the result is true, the second expression is evaluated; if +false, the third expression is evaluated. Metal evaluates only one of the second and +third expressions. The second and third expressions can be of any type if: +• The types of the second and third expressions match. +• There is a type conversion for one of the expressions that can make their types +match (for more about type conversions, see section 2.12). +• One expression is a vector and the other is a scalar, and the scalar can be widened +to the same type as the vector type. The resulting matching type is the type of the +entire expression. +11. The ones’ complement operator (~) acts upon one operand that needs to be of a scalar +or vector integer type. The result is the ones’ complement of its operand. +The right-shift (>>) and left-shift (<<) operators act upon all scalar and vector integer +type operands.

If the first operand is a vector, the rightmost +operand can be a vector or scalar. +The result of E1 << E2 is E1 left-shifted by the log2(N) least significant bits in E2 +viewed as an unsigned integer value: +• If E1 is a scalar, N is the number of bits used to represent the data type of E1. +• Or if E1 is a vector, N is the number of bits used to represent the type of E1 +elements. +For the left-shift operator, the vacated bits are filled with zeros. +The result of E1 >> E2 is E1 right-shifted by the log2(N) least significant bits in E2 +viewed as an unsigned integer value: +• If E1 is a scalar, N is the number of bits used to represent the data type of E1. +• Or if E1 is a vector, N is the number of bits used to represent the data type of E1 +elements. +For the right-shift operator, if E1 has an unsigned type or if E1 has a signed type and a +nonnegative value, the vacated bits are filled with zeros. If E1 has a signed type and a +negative value, the vacated bits are filled with ones. +12. The assignment operator behaves as described by the C++17 Specification. For the +lvalue = expression assignment operation, if expression is a scalar type and +lvalue is a vector type, the scalar converts to the element type used by the vector +operand. The scalar type then widens to a vector that has the same number of +components as the vector operand. Metal performs the operation componentwise, +which results in a same size vector. +Other C++17 operators that are not detailed above — such as sizeof(T), unary (&) operator, +and comma (,) operator — behave as described in the C++17 Specification. +Unsigned integers shall obey the laws of arithmetic modulo 2n, where n is the number of bits in +the value representation of that particular size of integer. The result of signed integer overflow +is undefined. +For integral operands the divide (/) operator yields the algebraic quotient with any fractional +part discarded. (This is often called truncation towards zero.)

An address space attribute specifies the region of memory from where buffer +memory objects are allocated. These attributes describe disjoint address spaces that can also +specify access restrictions: +• device (see section 4.1) +• constant (see section 4.2) +• thread (see section 4.3) +• threadgroup (see section 4.4) +• threadgroup_imageblock (see section 4.5) +• ray_data (see section 4.6) +• object_data (see section 4.7) +All OS: Metal 1 and later support the device, threadgroup, constant, and thread +attributes. Metal 2.3 and later support ray_data attributes. Metal 3 and later support +object_data attributes. +iOS: Metal 2 and later support the threadgroup_imageblock attribute. +macOS: Metal 2.3 and later support the threadgroup_imageblock attribute. +All arguments to a graphics or kernel function that are a pointer or reference to a type needs to +be declared with an address space attribute. For graphics functions, an argument that is a +pointer or reference to a type needs to be declared in the device or constant address +space. For kernel functions, an argument that is a pointer or reference to a type needs to be +declared in the device, threadgroup, threadgroup_imageblock, or constant address +space. The following example introduces the use of several address space attributes. (The +threadgroup attribute is supported here for the pointer l_data only if foo is called by a +kernel function, as detailed in section 4.4.) +void foo(device int *g_data, +threadgroup int *l_data, +constant float *c_data) +{…} +The address space for a variable at program scope needs to be constant. +Any variable that is a pointer or reference needs to be declared with one of the address space +attributes discussed in this section. If an address space attribute is missing on a pointer or +reference type declaration, a compilation error occurs. +4.1 Device Address Space +The device address space name refers to buffer memory objects allocated from the device +memory pool that are both readable and writeable. +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 100 of 346 + +================================================================================ +=== PAGE 101 === +================================================================================ +A buffer memory object can be declared as a pointer or reference to a scalar, vector or user- +defined structure. In an app, Metal API calls allocate the memory for the buffer object, which +determines the actual size of the buffer memory. +Some examples are: +// An array of a float vector with four components. +device float4 *color; +struct Foo { +float a[3]; +int b[2]; +}; +// An array of Foo elements. +device Foo *my_info; +Because you always allocate texture objects from the device address space, you don’t need the +device address attribute for texture types. You cannot directly access the elements of a +texture object, so use the built-in functions to read from and write to a texture object (see +section 6.12). +4.2 Constant Address Space +The constant address space name refers to buffer memory objects allocated from the device +memory pool that are read-only. You must declare variables in program scope in the constant +address space and initialize them during the declaration statement. The initializer(s) expression +must be a core constant expression. (Refer to section 5.20 of the C++17 specification.) The +compiler may evaluate a core constant expression at compile time. Variables in program scope +have the same lifetime as the program, and their values persist between calls to any of the +compute or graphics functions in the program. +constant float samples[] = { 1.0f, 2.0f, 3.0f, 4.0f }; +Pointers or references to the constant address space are allowed as arguments to functions. +Writing to variables declared in the constant address space is a compile-time error. Declaring +such a variable without initialization is also a compile-time error. +Buffers in the constant address space passed to kernel, vertex, and fragment functions have +minimum alignment requirements based on the GPU. See “Minimum constant buffer offset +alignment” in the Metal Feature Set Tables for more information. +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 101 of 346 + +================================================================================ +=== PAGE 102 === +================================================================================ +4.3 Thread Address Space +The thread address space refers to the per-thread memory address space.

Variables declared inside a +graphics or kernel function are allocated in the thread address space. +[[kernel]] void +my_kernel(…) +{ +// A float allocated in the per-thread address space +float x; +// A pointer to variable x in per-thread address space +thread float * p = &x; +… +} +4.4 Threadgroup Address Space +A GPU compute unit can execute multiple threads concurrently in a threadgroup, and a GPU can +execute a separate threadgroup for each of its compute units. +Threads in a threadgroup can work together by sharing data in threadgroup memory, which +is faster on most devices than sharing data in device memory. Use the threadgroup +address space to: +• Allocate a threadgroup variable in a kernel, mesh, or object function. +• Define a kernel, fragment, or object function parameter that’s a pointer to a threadgroup +address. +See the Metal Feature Set Tables to learn which GPUs support threadgroup space +arguments for fragment shaders. +Threadgroup variables in a kernel, mesh, or object function only exist for the lifetime of the +threadgroup that executes the kernel. Threadgroup variables in a mid-render kernel function +are persistent across mid-render and fragment kernel functions over a tile. +This example kernel demonstrates how to declare both variables and arguments in the +threadgroup address space.

Metal 2.1 and later support quad- +group functions. +iOS: Metal 2.2 and later support some SIMD-group functions. Metal 2 and later support quad- +group functions. +Within a threadgroup, you can divide threads into SIMD-groups, which are collections of +threads that execute concurrently. The mapping to SIMD-groups is invariant for the duration of +a kernel’s execution, across dispatches of a given kernel with the same launch parameters, and +from one threadgroup to another within the dispatch (excluding the trailing edge threadgroups +in the presence of nonuniform threadgroup sizes). In addition, all SIMD-groups within a +threadgroup needs to be the same size, apart from the SIMD-group with the maximum index, +which may be smaller, if the size of the threadgroup is not evenly divisible by the size of the +SIMD-groups. +A quad-group is a SIMD-group with the thread execution width of 4. +For more about kernel function attributes for SIMD-groups and quad-groups, see section +5.2.3.6. For more about threads and thread synchronization, see section 6.9 and its +subsections: +• For more about thread synchronization functions, including a SIMD-group barrier, see +section 6.9.1. +• For more about SIMD-group functions, see section 6.9.2. +• For more about quad-group functions, see section 6.9.3. +4.5 Threadgroup Imageblock Address Space +The threadgroup_imageblock address space refers to objects allocated in threadgroup +memory that are only accessible using an imageblock object (see section 2.11). A +pointer to a user-defined type allocated in the threadgroup_imageblock address space +can be an argument to a tile shading function (see section 5.1.9). There is exactly one +threadgroup per tile, and each threadgroup can access the threadgroup memory and the +imageblock associated with its tile. +• Variables allocated in the threadgroup_imageblock address space in a kernel function +are allocated for each threadgroup executing the kernel, are shared by all threads in a +threadgroup, and exist only for the lifetime of the threadgroup that executes the kernel. +Each thread in the threadgroup uses explicit 2D coordinates to access imageblocks. Do not +assume any spatial relationship between the threads and the imageblock. The threadgroup +dimensions may be smaller than the tile size. +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 103 of 346 + +================================================================================ +=== PAGE 104 === +================================================================================ +4.6 Ray Data Address Space +All OS: Metal 2.3 and later support ray_data address space. +The ray_data address space refers to objects allocated in a memory that is only accessible in +an intersection function (see section 5.1.6) for ray tracing. Intersection functions can read and +write to a custom payload using [[payload]] attribute (see Table 5.10) in the ray_data +address space. When a shader calls intersect() (see section 6.18.2) with a payload, the +system copies the payload to the ray_data address space, calls the intersection function, and +when the intersection function returns, it copies the payload back out. +4.7 Object Data Address Space +All OS: Metal 3 and later support object_data address space. +Object functions use the object_data address space to pass a payload to a mesh function +(see section 5.2.3.9). The object_data address space behaves like the threadgroup +address space in that the programming model is explicitly cooperative within the threadgroup. +Use the threads in the threadgroup to efficiently compute the payload and value +mesh_grid_properties::set_threadgroups_per_grid. The payload in the +object_data address space is not explicitly bound or initialized, and the implementation +manages its lifetime. +4.8 Memory Coherency +All OS: Metal 3.2 and later support coherent(device) qualifier and memory_coherence +on textures for Apple silicon. +Memory operations in Metal have a concept of a scope of coherency. For a store, the scope of +coherence describes the set of threads that may observe the result of the store if you properly +synchronize them, and for a load, it describes the set of threads with stores the load may +observe if you properly synchronize them. Metal has the following scope of coherence: +• Thread coherence — memory writes are only visible to the thread. +• Threadgroup coherence — memory writes are only visible to threads within their +threadgroup. +• Device coherence — memory writes are visible to all threads on the device, that is, +threads across threadgroups. +Memory in the thread address space has thread coherence, and memory in the +threadgroup address space has threadgroup coherence. By default, memory in the device +address space has threadgroup coherence. +Metal 3.2 and later support the coherent(device) qualifiers for buffers and +memory_coherence_device for textures to indicate that the object has device coherence, +that is, memory operations are visible across threads on the device if you properly synchronize +them. +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 104 of 346 + +================================================================================ +=== PAGE 105 === +================================================================================ +[[kernel]] void example( +coherent device float *dptr1, +coherent(device) device float4 *dptr2, +texture2d tex, +texture2d tex2) +{…} +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 105 of 346 + +================================================================================ +=== PAGE 106 === +================================================================================ +5 Function and Variable Declarations +This chapter describes how you declare functions, arguments, and variables.

They can also call functions with the +[[intersection(…)]] attribute by calling intersect() (see section 6.18.2). +In Metal 2.1 and earlier, the Metal compiler ignores namespace identifiers for kernel, vertex, and +fragment functions. In Metal 2.2 and later, if you declare a qualified function within a +namespace, you must include the namespace identifier with the function’s name each time you +refer it to a Metal Framework API.

The following example shows the syntax for declaring a vertex: +vertex void +my_vertex_func(…) +{…} +[[vertex]] void +vertex_func2(…) +{…} +For a vertex function, the return type identifies the output generated by the function. If the +vertex function does not generate output, it shall return void and can only be used in a render +pipeline with rasterization disabled. +5.1.1.1 Post-Tessellation Vertex Functions +All OS: Metal 1.2 and later support post-tessellation vertex functions (patch attribute). +The post-tessellation vertex function calculates the vertex data for each surface sample on the +patch produced by the fixed function tessellator. The inputs to the post-tessellation vertex +function are: +• Per-patch data. +• Patch control point data. +• The tessellator stage output (the normalized vertex location on the patch). +The post-tessellation vertex function generates the final vertex data for the tessellated +triangles. For example, to add additional detail (such as displacement mapping values) to the +rendered geometry, the post-tessellation vertex function can sample a texture to modify the +vertex position by a displacement value. +After the post-tessellation vertex function executes, the tessellated primitives rasterize. +The post-tessellation vertex function is a vertex function identified using the ordinary vertex +function attribute. +5.1.1.2 Patch Type and Number of Control Points Per-Patch +The [[patch]] attribute is required for the post-tessellation vertex function. +For macOS, the [[patch(patch-type, N)]] attribute must specify both the patch type +(patch-type is either quad or triangle) and the number of control points in the patch (N +needs to be a value from 0 to 32). For iOS, specifying the patch-type is required, but the +number of control points is optional. +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 107 of 346 + +================================================================================ +=== PAGE 108 === +================================================================================ +If the number of control points are specified in the post-tessellation vertex function, this +number must match the number of control points provided to the drawPatches or +drawIndexedPatches API. +Example: +[[patch(quad)]] +[[vertex]] vertex_output +my_post_tessellation_vertex(…) +{…} +[[patch(quad, 16)]] +[[vertex]] vertex_output +my_bezier_vertex(…) +{…} +5.1.2 Fragment Functions +You can declare the fragment or since Metal 2.3 [[fragment]] attribute only for a +graphics function.

The [[stitchable]] attribute implies [[visible]], +which means that stitchable functions can be used in all contexts where a visible function can +be used as described in Sec 5.1.4.

With TBDR, commands are buffered until a large list of commands +accumulates. The hardware divides the framebuffer into tiles and then renders only the +primitives that are visible within each tile. Tile shading functions support performing compute +operations in the middle of rendering, which can access memory more efficiently by reducing +round trips to memory and utilizing high-bandwidth local memory. +A tile function launches a set of threads called a dispatch, which is organized into threadgroups +and grids. You may launch threads at any point in a render pass and as often as needed. Tile +functions barrier against previous and subsequent draws, so a tile function does not execute +until all earlier draws have completed. Likewise, later draws do not execute until the tile function +completes. +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 113 of 346 + +================================================================================ +=== PAGE 114 === +================================================================================ +GPUs always process each tile and each dispatch to completion. Before processing the next +tile, all draws and dispatches for a tile launch in submission. +Tile functions have access to 32 KB of threadgroup memory that may be divided between +imageblock storage and threadgroup storage. (For more information about the threadgroup +memory size, see section 4.4.) The imageblock size is dependent on the tile width, tile height, +and the bit depth of each sample. Either the render pass attachments (which use implicit +imageblock layout; see section 5.6.3.1) or function-declared structures (which use explicit +imageblock layout; see section 5.6.3.2) determines the bit depth of the sample. For more about +how kernel functions utilize the threadgroup_imageblock address space, see section 4.5. +5.1.10 Host Name Attribute +All OS: Metal 2.2 and later support the host name attribute. +In Metal 2.2 and later, you can override the default name that the Metal Framework API uses to +refer to a qualified function. Add the [[host +name(name)]] attribute to the function +_ +declaration, where name is the string literal that the Metal Framework API will use to reference +the function name. The compiler raises a compile time error if you give different functions the +same name. For example: +// Metal API name is abc +[[host_name("abc")]] [[kernel]] void funcA() {} +// Metal API name is xyz +[[host_name("xyz")]] [[kernel]] void funcX() {} +5.1.11 Templated Qualified Functions +All OS: Metal 2.2 and later support the template qualified functions. +In Metal 2.2 and later, you can use templates for qualified functions (for example, vertex, +fragment, visible, and kernel functions) declarations. You must explicitly instantiate the +template to force the compiler to emit code for a given specialization. For example: +template +kernel void bar(device T *x) { … } +// Explicit specialization of `bar` with [T = int] +template kernel void bar(device int *); +The compiler gives all specializations the same name unless one uses the +[[host +_ +name(name)]] attribute to provide a different name for each specialization. +// Explicit specialization of `bar` with [T = int] and host_name +// "bar_int" +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 114 of 346 + +================================================================================ +=== PAGE 115 === +================================================================================ +template [[host_name("bar_int")]] kernel void bar(device int *); +// Explicit specialization of `bar` with [T = float] and +// host_name "bar_float" +template [[host_name("bar_float")]] kernel void bar(device float *); +5.1.12 User Annotation Attribute +All OS: Metal 4 and later support the user annotation attribute. +You can annotate a qualified function with a name and look it up using the Metal Framework +reflection API. Add the [[user_annotation(“string”)]] attribute to a qualified function +where string is the annotation you want to associate with a function. When you add a +user_annotation attribute to a templated qualified function, all instantiations inherit that +annotation unless you override it using a user_annotation attribute on that instantiation. For +example: +[[user_annotation("basecase"), kernel]] void funcB() {…} +template [[user_annotation("Tcase"), kernel]] +void funcTmpl(device T *x) {…} +// Inherit from user_annotation. +template [[host_name(“funcImplInt”), kernel]] +void funcImpl(device int* x) {…} +// Override user +annotation. +_ +template [[host_name(“funcImplFloat”), +user_annotation("FPoverride"), +kernel]]]] +void funcImpl(device float* x) {…} +When looking up the annotation for the funcB using the Metal Framework API, you get back +basecase. For funcImplInt, you get back Tcase, and for funcImplFloat, you get back +FPoverride. +5.2 Function Arguments and Variables +Most inputs and outputs to graphics (vertex or fragment) and kernel functions are passed as +arguments. (Initialized variables in the constant address space and samplers declared in +program scope are inputs and outputs that do not have to be passed as arguments.) +In Metal 3.1 and later provide built-in input variables for kernel, mesh, and object shaders that +you declare in program scope, avoiding the need for passing them as arguments. This applies if +you don’t use them in a dynamic library or a separately compiled binary function.

Unlike when passing as +arguments in a shader, you can’t assume different global variables are non-aliased. You need to +specify the binding indexes because Metal can’t set them automatically. +Arguments to graphics and kernel functions can be any of the following: +• Device buffer — A pointer or reference to any data type in the device address space (see +section 2.8). +• Constant buffer — A pointer or reference to any data type in the constant address space +(see section 2.8). +• A texture object (see section 2.9) or an array of textures. +• A texture_buffer object (see section 2.9.1) or an array of texture buffers. +• A sampler object (see section 2.10) or an array of samplers. +• A buffer shared between threads in a threadgroup — a pointer to a type in the +threadgroup address space that can only be used as arguments for kernel functions. +• An imageblock (see section 2.11). +• An argument buffer (see section 2.13). +• A visible function table (see section 2.15) for kernel functions. In Metal 2.4 and later, visible +function table can also be used in graphic functions. +• An intersection function table (see section 2.17.3) for kernel functions. +• An acceleration structure (see section 6.18.1) for intersection functions. +• A tensor (see section 2.21). +• A structure with elements that are buffers, textures, or texture buffers. +Buffers (device) specified as argument values to a graphics or kernel function cannot alias; that +is, a buffer passed as an argument value cannot overlap another buffer passed to a separate +argument of the same graphics or kernel function. +You cannot declare arguments to graphics and kernel functions to be of type size_t, +ptrdiff_t, or a structure and/or union that contains members declared to be one of these +built-in scalar types. +The arguments to these functions are often specified with attributes to provide further +guidance on their use. Attributes are used to specify: +• The resource location for the argument (see section 5.2.1). +• Built-in variables that support communicating data between fixed-function and +programmable pipeline stages (see section 5.2.3). +• Which data is sent down the pipeline from vertex function to fragment function (see section +5.2.4). +5.2.1 Locating Buffer, Texture, and Sampler Arguments +For each argument, an attribute can be optionally specified to identify the location of a buffer, +texture, or sampler to use for this argument type.

The [[raster_order_group(index)]] attribute used for a buffer or texture +guarantees the order of accesses for any overlapping fragments from different primitives that +map to the same (x,y) pixel coordinate and sample, if per-sample shading is active. +The [[raster_order_group(index)]] attribute can be specified on a texture (which is +always in device memory) or a buffer that is declared in device memory, but not in either the +threadgroup or constant address space. The [[raster_order_group(index)]] +attribute cannot be used with a structure or class. +Fragment function invocations that mark overlapping accesses to a buffer or texture with the +[[raster_order_group(index)]] attribute are executed in the same order as the +geometry is submitted. For overlapping fragment function invocations, writes performed by a +fragment function invocation to a buffer or texture marked with the +[[raster_order_group(index)]] attribute needs to be available to be read by a +subsequent invocation and must not affect reads by a previous invocation. Similarly, reads +performed by a fragment function invocation must reflect writes by a previous invocation and +must not reflect writes by a subsequent invocation. +The index in [[raster_order_group(index)]] is an integer value that specifies a +rasterizer order ID, which provides finer grained control over the ordering of loads and stores. +For example, if two buffers A and B are marked with different rasterizer order ID values, then +loads and stores to buffers A and B for overlapping fragments can be synchronized +independently. +Example: +fragment void +my_fragment(texture2d texA +[[raster_order_group(0), texture(0)]], +…) +{ +ushort2 coord; +float4 clr = texA.read(coord); +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 119 of 346 + +================================================================================ +=== PAGE 120 === +================================================================================ +// do operations on clr +clr = …; +texA.write(clr, coord); +} +For an argument buffer, you can use the [[raster_order_group(index)]] attribute on a +buffer or texture member in a structure. +5.2.2 Attributes to Locate Per-Vertex Inputs +A vertex function can read per-vertex inputs by indexing into a buffer(s) passed as arguments +to the vertex function using the vertex and instance IDs. In addition, you can also declare per- +vertex input with the [[stage_in]] attribute and pass that input as an argument. For per- +vertex input passed as an argument declared with the [[stage_in]] attribute, each element +of the per-vertex input must specify the vertex attribute location as +[[attribute(index)]]. For more about the [[stage_in]] attribute, see section 5.2.4. +The index value is an unsigned integer that identifies the assigned vertex input location. The +proper syntax is for the attribute to follow the argument or variable name. The Metal API uses +this attribute to identify the location of the vertex buffer and describe the vertex data such as +the buffer to fetch the per-vertex data from, its data format, and its stride. +The following example shows how to assign vertex attributes to elements of a vertex input +structure that is passed to a vertex function using the stage_in attribute: +struct VertexInput { +float4 position [[attribute(0)]]; +float3 normal [[attribute(1)]]; +half4 color [[attribute(2)]]; +half2 texcoord [[attribute(3)]]; +}; +constexpr constant uint MAX_LIGHTS = 4; +struct LightDesc { +uint num_lights; +float4 light_position[MAX_LIGHTS]; +float4 light_color[MAX_LIGHTS]; +float4 light_attenuation_factors[MAX_LIGHTS]; +}; +constexpr sampler s = sampler(coord::normalized, +address::clamp_to_zero, +filter::linear); +vertex VertexOutput +render_vertex(VertexInput v_in [[stage_in]], +constant float4x4& mvp_matrix [[buffer(1)]], +constant LightDesc& lights [[buffer(2)]], +uint v_id [[vertex_id]]) +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 120 of 346 + +================================================================================ +=== PAGE 121 === +================================================================================ +{ +VertexOutput v_out; +… +return v_out; +} +The example below shows how both buffers and the stage_in attribute can be used to fetch +per-vertex inputs in a vertex function: +struct VertexInput { +float4 position [[attribute(0)]]; +float3 normal [[attribute(1)]]; +}; +struct VertexInput2 { +half4 color; +half2 texcoord[4]; +}; +constexpr constant uint MAX_LIGHTS = 4; +struct LightDesc { +uint num_lights; +float4 light_position[MAX_LIGHTS]; +float4 light_color[MAX_LIGHTS]; +float4 light_attenuation_factors[MAX_LIGHTS]; +}; +constexpr sampler s = sampler(coord::normalized, +address::clamp_to_zero, +filter::linear); +vertex VertexOutput +render_vertex(VertexInput v_in [[stage_in]], +VertexInput2 v_in2 [[buffer(0)]], +constant float4x4& mvp_matrix [[buffer(1)]], +constant LightDesc& lights [[buffer(2)]], +uint v_id [[vertex_id]]) +{ +VertexOutput vOut; +… +return vOut; +} +A post-tessellation vertex function can read the per-patch and patch control-point data.

A thread is an instance of the kernel function that +executes for each point in this grid, and thread_position_in_grid identifies its position in +the grid. +Within a compute unit, a threadgroup is partitioned into multiple smaller groups for execution. +The execution width of the compute unit, referred to as the threads +_per_simdgroup, +determines the recommended size of this smaller group. For best performance, make the total +number of threads in the threadgroup a multiple of the threads +_per_simdgroup. +Threadgroups are assigned a unique position within the grid (referred to as +threadgroup_position_in_grid). Threads are assigned a unique position within a +threadgroup (referred to as thread_position_in_threadgroup). The unique scalar index +of a thread within a threadgroup is given by thread_index_in_threadgroup. +Each thread’s position in the grid and position in the threadgroup are N-dimensional tuples. +Threadgroups are assigned a position using a similar approach to that used for threads. +Threads are assigned to a threadgroup and given a position in the threadgroup with +components in the range from zero to the size of the threadgroup size in that dimension minus +one. +When a kernel function is submitted for execution, the number of threadgroups and the +threadgroup size are specified, or the number of threads in the grid and the threadgroup size +are specified. For example, consider a kernel function submitted for execution that uses a 2D +grid where the number of threadgroups specified are (Wx, Wy) and the threadgroup size is +(Sx, Sy). Let (wx, wy) be the position of each threadgroup in the grid +(threadgroup_position_in_grid) and (lx, ly) be the position of each thread in the +threadgroup (thread_position_in_threadgroup). +The thread position in the grid (thread_position_in_grid) is: +(gx, gy) = (wx * Sx + lx, wy * Sy + ly) +The grid size (threads_per_grid) is: +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 135 of 346 + +================================================================================ +=== PAGE 136 === +================================================================================ +(Gx, Gy) = (Wx * Sx, Wy * Sy) +In cases other than a tile function, the thread index in the threadgroup +(thread_index_in_threadgroup) is determined by: +ly * Sx + lx +For a tile function, the thread index is not a linear mapping from the lx and ly values.

The attribute +determines what sampling method the fragment function uses and how the interpolation is +performed, including whether to use perspective-correct interpolation, linear interpolation, or +no interpolation. +The sampling and interpolation attribute can be specified on any stage_in structure member +whose type is scalar and vector. The sampling and interpolation attributes supported are: +• center_perspective +• center_no_perspective +• centroid_perspective +• centroid_no_perspective +• sample_perspective +• sample_no_perspective +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 156 of 346 + +================================================================================ +=== PAGE 157 === +================================================================================ +• flat +center_perspective is the default sampling and interpolation attribute, with the following +exceptions: +• For a variable with the [[position]] attribute, the only valid sampling and interpolation +attribute is center_no_perspective. +• For an integer variable, the only valid sampling and interpolation attribute is flat. +A perspective attribute (center_perspective, centroid_perspective, or +sample_perspective) indicates the values across a primitive are interpolated in a +perspective-correct manner. A nonperspective attribute (center_no_perspective, +centroid_no_perspective, or sample_no_perspective) indicates the values across a +primitive are linearly interpolated in screen coordinates. +The center attribute variants (center_perspective and center_no_perspective) +cause sampling to use the center of each pixel. +The sampling attribute variants (sample_perspective and sample_no_perspective) +cause interpolation at a sample location rather than at the pixel center. With one of these +attributes, the fragment function (or code blocks in the fragment function) that use these +variables execute per-sample rather than per-fragment. +If a centroid attribute variant is specified (centroid_perspective and +centroid_no_perspective), the interpolation point sampled needs to be within both the +primitive and the centroid of the pixel. +The following example demonstrates how to specify the interpolation of data for different +members of a user-defined structure: +struct FragmentInput { +float4 pos [[center_no_perspective]]; +float4 color [[center_perspective]]; +float2 texcoord; +int index [[flat]]; +float f [[sample_perspective]]; +interpolant icolor; +}; +In Metal 2.4 and later, the sample and interpolation attribute can also be specified on any +stage_in structure member whose type is structure.

Field declarations in a structure where +sampling and interpolation qualifiers have been inherited are valid only if one of the following is +true: +• The type of field is compatible with the inherited qualifiers. +• The field declaration does not have a sampling, and interpolation qualifiers attribute. +• The field declaration has the same sampling, and interpolation qualifiers attribute as the +inherited one. +The following example demonstrates how to specify the interpolation on structure types. +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 157 of 346 + +================================================================================ +=== PAGE 158 === +================================================================================ +struct VOut { +float4 pos [[position]]; +} +struct POut { +float4 color0; +float4 color1; +}; +[[mesh]] void mesh_function(mesh m) +struct FragmentInput { +VOut vin; +POut pin [[center _perspective]]; +}; +5.5 Per-Fragment Function Versus Per-Sample Function +You typically execute the fragment function per-fragment. The sampling attribute identifies if +fragment input interpolation is per-sample or per-fragment. Similarly, the [[sample_id]] +attribute identifies the current sample index, and the [[color(m)]] attribute identifies the +destination fragment color or sample color (for a multisampled color attachment) value. If you +use any of these attributes with arguments to a fragment function, the fragment function may +execute per-sample instead of per-pixel. (The implementation may decide to only execute the +code that depends on the per-sample values to execute per-sample and the rest of the +fragment function may execute per-fragment.) +Only the inputs with sample access specified (or declared with the [[sample_id]] or +[[color(m)]] attribute) differ between invocations per-fragment or per-sample, whereas +other inputs still interpolate at the pixel center. +The following example uses the [[color(m)]] attribute to specify that this fragment function +executes on a per-sample basis: +[[fragment]] float4 +my_fragment(float2 tex_coord [[stage_in]], +texture2d img [[texture(0)]], +sampler s [[sampler(0)]], +float4 framebuffer [[color(0)]]) +{ +return c = mix(img.sample(s, tex_coord), framebuffer, +mix_factor); +} +5.6 Imageblock Attributes +iOS: Metal 2 and later support imageblocks. +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 158 of 346 + +================================================================================ +=== PAGE 159 === +================================================================================ +macOS: Metal 2.3 and later support imageblocks for Apple silicon. +This section and its subsections describe several attributes for imageblocks, including the +[[imageblock_data(type)]] attribute that specifies input and output imageblock with an +explicit imageblock layout for a fragment function. +5.6.1 Matching Data Members of Master and View Imageblocks +You can use the [[user(name)]] attribute to specify an attribute name for a data member of +the imageblock data type for a fragment function.

(For more about the implicit imageblock layout, see section 5.6.3.1.) +• As a structure for declaring the imageblock data where the fragment function explicitly +specifies the storage layout of the imageblock. (For more about the explicit imageblock +layout, see section 5.6.3.2.) +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 163 of 346 + +================================================================================ +=== PAGE 164 === +================================================================================ +5.6.3.1 Implicit Imageblock Layout for Fragment Functions +You can access the imageblock data (all the data members in the imageblock associated with a +pixel) in a fragment function. Metal creates an implicit imageblock that matches the behavior of +color attachments (for input to and output from a fragment function). In this mode, the types +associated with the color attachments, as described in the fragment function, are the ALU +types (that is, the types used to perform computations in the fragment function). The Metal +runtime defines the actual pixel storage format. +When accessing the imageblock data as color attachments, you cannot declare the pixel +storage types described in section 2.7 in the imageblock slice structure. +For an imageblock data implicit layout of type T, T is a structure where each member satisfies +one of the following: +• Have a color attachment (see the [[color(m)]] attribute in Table 5.5 of section +5.2.3.4). The color index m needs to be unique for each member (and sub-member) of T. +• Be a structure type with members that satisfy the constraint on the list. +5.6.3.2 Explicit Imageblock Layout for Fragment Functions +The imageblock data with explicit layout has its layout declared in the shading function, not via +the runtime as is done for color attachments. You declare the imageblock data for an explicit +layout as a structure. Each data member of the per-fragment imageblock data can be: +• A scalar or vector, integer or floating-point data type. +• One of the pixel data types described in section 2.7. +• An array of these types. +• Or a structure built with these types. +The data members of the imageblock structure use the appropriate alignment rules for each +data member type declared in the structure to determine the actual structure layout and size. +A fragment function can read one or more data members in the per-fragment imageblock data +and write to one or more data members in the per-fragment imageblock data. You can declare +the input and output imageblock data to a fragment function as a structure. The input and +output imageblock structures can be the fully explicit imageblock structure (referred to as the +master explicit imageblock structure), or be a subset of the master explicit imageblock +structure (referred to as the imageblock view structure). For the latter, use the +[[imageblock_data(type)]] attribute with the input and output imageblock data +structure specified on a fragment function, where type specifies the fully explicit imageblock +data structure. +If you specify the [[imageblock_data]] attribute on the input argument or output +structure element without type, by default the fragment function uses the master explicit +imageblock data structure on the input or output. +Example: +struct I { +float a [[raster_order_group(0)]]; +}; +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 164 of 346 + +================================================================================ +=== PAGE 165 === +================================================================================ +struct FragOut { +float c [[color(0)]]; +I i [[imageblock_data]]; +}; +fragment FragOut +my_fragment(I i [[imageblock_data]]) +{ +FragOut fragOut; +… +return fragOut; +} +Fragment functions can access both an implicit imageblock and an explicit imageblock as +separate input arguments, or as fields in a return structure. +Example: +struct I { +float a [[raster_order_group(0)]]; +}; +struct FragOut { +float c [[color(0)]]; +I i [[imageblock_data]]; +}; +[[fragment]] FragOut +my_fragment(I i [[imageblock_data]], +float c [[color(0)]]) +{ +FragOut fragOut; +… +return fragOut; +} +By default, the explicit imageblock storage is separate from the storage of the implicit +imageblock. To share storage between the explicit imageblock and implicit imageblock, see +section 5.6.5. +5.6.4 Imageblock Layouts in Kernel Functions +The imageblock type (defined in the header ) can only be used +for arguments declared in a kernel function or in a user function that is called by a kernel +function.

The color index m needs to be unique for each member (and sub-member) of +T. +If you do not specify an imageblock layout, the compiler deduces the layout based on T. If T is +not compatible with an implicit or explicit imageblock, a compiler error occurs. +Both explicit and implicit imageblocks can be arguments to a kernel function. This also makes it +easy to share explicit and implicit imageblock structures between fragment and kernel +functions. By default, the explicit imageblock storage is separate from the storage of the +implicit imageblock. To share storage between the explicit imageblock and implicit imageblock, +see section 5.6.5. +5.6.5 Aliasing Explicit and Implicit Imageblocks +By default, explicit and implicit imageblocks do not alias. To alias the allocation of an explicit +imageblock with the implicit imageblock fully or partially, you can use the following attributes to +specify an explicit imageblock: +[[alias_implicit_imageblock]] +[[alias_implicit_imageblock_color(n)]] +The [[alias_implicit_imageblock]] attribute specifies that the explicit imageblock +allocation completely aliases the implicit imageblock. +The [[alias_implicit_imageblock_color(n)]] attribute specifies that the explicit +imageblock allocation aliases the implicit imageblock starting at a specific color attachment +given by color(n). If n is a value that is between the smallest and largest declared +attachments, inclusive, but n references an undeclared attachment, then a compile-time error +occurs. If n is a value that exceeds the number of declared attachments, then compilation +succeeds, but the attribute is ignored. +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 166 of 346 + +================================================================================ +=== PAGE 167 === +================================================================================ +The behavior of accessing data members of an aliased implicit imageblock with an explicit +imageblock is undefined if the kernel or fragment function modifies the aliased imageblock data +members using the explicit imageblock and its associated member functions. +Example: +struct I { +rgba8unorm a; +rgb9e5 b; +int c; +float d; +}; +struct FragOut { +float4 finalColor [[color(0)]]; +I i [[imageblock_data, alias_implicit_imageblock_color(1)]]; +}; +[[fragment]] FragOut +my_fragment(I i [[imageblock_data]], …) +{ +FragOut fragOut; +… +return fragOut; +} +5.6.6 Imageblocks and Function Constants +Do not use [[function_constant(name)]] with data members of an imageblock +structure either as input to or as returned output from a fragment or kernel function. +5.7 Graphics Function — Signature Matching +A graphics function signature is a list of parameters that are either input to or output from a +graphics function. +5.7.1 Vertex — Fragment Signature Matching +You can pass two kinds of data between a vertex and fragment function: user-defined and +built-in variables. +You can declare the per-instance input to a fragment function with the [[stage_in]] +attribute.

If they are used and read in a +fragment function, the shader has undefined behavior. +You may also declare built-in variables that are rasterizer output or refer to a framebuffer color +value as the fragment function input with the appropriate attribute. +You can also use the attribute [[user(name)]] syntax to specify an attribute name for any +user-defined variable. +A vertex function and a fragment function have matching signatures if: +• There is no input argument with the [[stage_in]] attribute declared in the fragment +function. +• For a fragment function argument declared with [[stage_in]], each element in the type +associated with this argument can be one of the following: a built-in variable generated by +the rasterizer, a framebuffer color value passed as input to the fragment function, or a user- +generated output from a vertex function. For built-in variables generated by the rasterizer or +framebuffer color values, there is no requirement to associate a matching type with +elements of the vertex return type. For elements that are user-generated outputs, the +following rules apply: +If you specify an attribute name for an element using [[user(name)]], the attribute name +must match with an element in the return type of the vertex function.

In Metal 2 and later, you can use a +function constant to specify the binding number for a resource (see section 5.8.1.4), to specify +the index for the color() or raster_order_group attributes (section 5.8.1.5), and to +identify that a structure element is optional (section 5.8.1.6). +Function constants enable the generation of multiple variants of a function. Without using +function constants, you can compile one function many times with different preprocessor +macro defines to enable different features (an ubershader). Using preprocessor macros for +ubershaders with offline compiling can result in many variants and a significant increase in the +size of the shading function library assets. Function constants provide the same ease of use as +preprocessor macros but moves the generation of the specific variants to the creation of the +pipeline state, so you don't have to compile the variants offline. +5.8.1 Specifying Program Scope Function Constants +Program scope variables declared with (or initialized with) the following attribute are function +constants: +[[function_constant(index)]] +The value index needs to be between 0 and 65535. +In Metal, function constants can: +• Control code paths that get compiled. +• Specify the optional arguments of a function (graphics, kernel, or user functions). +• Specify optional elements of a structure with the [[stage_in]] attribute. +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 172 of 346 + +================================================================================ +=== PAGE 173 === +================================================================================ +You don’t initialize function constants in the Metal function source.

The behavior is similar to function constants for elements with the +[[stage_in]] attribute, as described in section 5.8.1.3. +If the value of the function constant variable given by name is nonzero or true (determined +during the render or compute pipeline state creation), the element in the structure is declared in +the function signature.

With [[viewport_array_index]], the vertex function output specifies +the rasterization viewport and scissor rectangle from the arrays specified by the +setViewports:count: and setScissorRects:count: framework calls, respectively. +The unclamped value of the vertex function output for [[viewport_array_index]] is +provided as input to the fragment function, even if the value is out of range. +The behavior of the fragment function with an unclamped [[viewport_array_index]] +value depends upon the implementation. Either Metal can render every primitive to +viewport/scissor rectangle 0, regardless of the passed value, or Metal can render to the nth +viewport/scissor rectangle, where n is the clamped value. (Hardware that does not support this +feature acts as only one viewport and one scissor rectangle are permitted, so the value for +[[viewport_array_index]] is 0.) +You can specify [[viewport_array_index]] in a post-tessellation vertex function. You +cannot specify [[viewport_array_index]] in the tessellation factor buffer. +Specifying [[viewport_array_index]] as fragment function input counts against the +number of input assembly components available. (Input assembly components are the +fragment function inputs declared with the stage_in qualifier.) +You must return the same value of [[viewport_array_index]] for every vertex in a +primitive. If the values differ, the behavior and the value passed to the fragment function are +undefined. The same behavior applies to primitives generated by tessellation. +5.11 Additional Restrictions +MSL functions and arguments have these additional restrictions: +• Writes to a buffer from a vertex function are not guaranteed to be visible to reads from the +associated fragment function of a given primitive. +• If a vertex function does writes to one or more buffers or textures, its return type needs to +be void. +• The return type of a vertex or fragment function cannot include an element that is a packed +vector type, matrix type, a structure type, a reference, or a pointer to a type. +• The number of inputs to a fragment function declared with the stage_in attribute is +limited. The input limits differ for different feature sets. The Metal Feature Set Tables lists +the specific limits below “Implementation Limits by GPU Family” +. (An input vector counts as +n input scalars, where n is the number of components in the vector.) +• The argument type for arguments to a graphics or kernel function cannot be a derived class. +Also, the type of an argument to a graphics function that is declared with the stage_in +attribute cannot be a derived class. +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 180 of 346 + +================================================================================ +=== PAGE 181 === +================================================================================ +6 Metal Standard Library +This chapter describes functions in the Metal Standard Library (MSLib). +6.1 Namespace and Header Files +Metal declares all MSLib functions and enumerations in the metal namespace.

This is useful in cases where you want +a threshold function with a smooth transition. +This is equivalent to: +t = clamp((x – edge0)/(edge1 – +edge0), 0, 1); +return t * t * (3 – 2 * t); +Results are undefined if edge0 >= edge1 or if +x, edge0, or edge1 is a NaN. +T step(T edge, T x) Returns 0.0 if x < edge; otherwise, it returns +1.0. +For single precision floating-point, Metal also supports a precise and fast variant of the +following common functions: clamp and saturate. The difference between the Fast and +precise function variants handle NaNs differently. In the fast variant, the behavior of NaNs is +undefined, whereas the precise variants follow the IEEE 754 rules for NaN handling.

In particular: +• Fragments corresponding to helper threads are discarded when the fragment function +execution is complete without any updates to the render targets. +• Stores and atomic operations to buffers and textures performed by helper threads have no +effect on the underlying memory associated with the buffer or texture. +6.10.1.1 Fragment Functions – Derivatives +Metal includes the functions in Table 6.19 to compute derivatives.

The offset is an integer +value applied to the texture coordinate before looking up each pixel. This integer value can be in +the range -8 to +7; the default value is 0. +The texture sample, sample_compare, gather, and gather_compare functions require +that you declare the texture with the sample access attribute. The texture read functions +require that you declare the texture with the sample, read, or read_write access attribute. +The texture write functions require that you declare the texture with the write or +read_write access attribute. (For more about access attributes, see section 2.9.) +The texture sample_compare and gather_compare functions are only available for depth +texture types. +compare_func sets the comparison test for the sample_compare and gather_compare +functions. For more about compare_func, see section 2.10. +Overloaded variants of the texture sample and sample_compare functions with an +lod_options argument are available for a 2D texture, 2D texture array, 2D depth texture, 2D +depth texture array, 3D texture, cube texture, cube texture array, cube depth texture, and cube +depth texture array. (LOD/lod is short for level-of-detail.) The values for lod_options are: +• level(float lod) — Sample from the specified mipmap level. +• bias(float value) — Apply the specified bias to a mipmap level before sampling. +• gradient*(T dPdx, T dPdy) — Apply the specified gradients with respect to the x +and y directions. The texture type changes the name and the arguments; for example, for +3D textures, the name is gradient3d and the arguments are float3 type. +• min_lod_clamp(float lod) — Specify lowest mipmap level for sampler access, which +restricts sampler access to a range of mipmap levels. (All OS: Support since Metal 2.2.) +In macOS, Metal 2.2 and earlier don’t support sample_compare, bias and gradient* +functions, and lod needs to be a zero constant. Metal 2.3 and later lift this restriction for Apple +silicon. +In Metal 2.2 and later, you can specify a LOD range for a sampler. You can either specify a +minimum and maximum mipmap level or use min_lod_clamp to specify just the minimum +mipmap level of an open range. When the sampler determines which mipmaps to sample, the +selection is clamped to the specified range. +Clamping the LOD is useful where some of the texture data is not available all the time (for +example, texture streaming). You can create a texture with all the necessary mipmaps and then +can stream image data starting from the smallest mipmaps. When the GPU samples the texture, +it clamps to the mipmaps that already have valid data. When you copy larger mipmaps into the +texture, you reduce the minimum LOD level. As new data becomes ready, you can change the +LOD clamp, which changes the sampling resolution. +The texture sample and sample_compare functions that don’t take an explicit LOD or +gradients when you don’t call them in a fragment function, have a default LOD of 0. In a +fragment function, the texture sample and sample_compare functions that don’t take an +explicit LOD or gradients calculate an implicit LOD by taking the derivative of the texture +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 217 of 346 + +================================================================================ +=== PAGE 218 === +================================================================================ +coordinate passed to the function. The gather and gather_compare functions you don’t call +in a fragment function also have a default LOD of 0. +For the gather and gather_compare functions, place the four samples that contribute to +filtering into xyzw components in counter-clockwise order, starting with the sample to the +lower-left of the queried location. This is the same as nearest sampling with unnormalized +texture coordinate deltas at the following locations: (-,+), (+,+), (+,-), (- +, +-), where the +magnitude of the deltas is always half a pixel. +A read from or write to a texture is out-of-bounds if and only if any of these conditions is +met: +• the coordinates accessed are out-of-bounds +• the level of detail argument is out-of-bounds +• the texture is a texture array (texture?d_array type), and the array slice argument is +out-of-bounds +• the texture is a texturecube or texturecube_array type, and the face argument is +out-of-bounds +• the texture is a multisampled texture, and the sample argument is out-of-bounds +For all texture types, an out-of-bounds write to a texture is ignored. +For all texture types: +• For components specified in a pixel format, an out-of-bounds read returns a color with +components with the value zero. +• For components unspecified in a pixel format, an out-of-bounds read returns the default +value. +For unspecified color components in a pixel format, the default values are: +• 0, for components other than alpha. +• 1, for the alpha component. +In a pixel format with integer components, the alpha default value is represented as the integral +value 0x1. For a pixel format with floating-point or normalized components, the alpha default +value is represented as the floating-point value 1.0. +For example, for a texture with the MTLPixelFormatR8Uint pixel format, the default values +for unspecified integer components are G = 0, B = 0, and A = 1. For a texture with the +MTLPixelFormatR8Unorm pixel format, the default values for unspecified normalized +components are G = 0.0, B = 0.0, and A = 1.0. For a texture with depth or stencil pixel format +(such as MTLPixelFormatDepth24Unorm_Stencil8 or MTLPixelFormatStencil8), +the default value for an unspecified component is undefined. +In macOS, for Metal 2.2 and earlier, lod needs to be 0 for texture write functions. Metal 2.3 +and later lift this restriction for Apple silicon. +The following texture member functions are available to support sparse textures: +macOS: Metal 2.3 and later support sparse texture functions. +iOS: Metal 2.2 and later support sparse texture functions. +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 218 of 346 + +================================================================================ +=== PAGE 219 === +================================================================================ +• sparse_sample — sample from a sparse texture +• sparse_sample_compare — sample compare from a sparse texture +• sparse_gather — gather from a sparse texture +• sparse_gather_compare — gather compare from a sparse texture +These sparse texture member functions return a sparse_color structure that contains one or +more color values and a residency flag.

Metal atomic functions must operate on Metal atomic data, as +described in section 2.6. +Atomic operations play a special role in making assignments in one thread visible to another +thread. A synchronization operation on one or more memory locations is either an acquire +operation, a release operation, or both. A synchronization operation without an associated +memory location is a fence and can be either an acquire fence, a release fence, or both. In +addition, there are relaxed atomic operations that are not synchronization operations. +There are only a few kinds of operations on atomic types, although there are many instances of +those kinds. This section specifies each general kind. +Atomic functions are defined in the header . +6.15.1 Memory Order +The enumeration memory_order specifies the detailed regular (nonatomic) memory +synchronization operations (see section 29.3 of the C++17 specification) and may provide for +operation ordering: +enum memory_order { +memory_order_relaxed, +memory_order_seq_cst +}; +For atomic operations other than atomic_thread_fence, memory_order_relaxed is the +only enumeration value. With memory_order_relaxed, there are no synchronization or +ordering constraints; the operation only requires atomicity. These operations do not order +memory, but they guarantee atomicity and modification order consistency. A typical use for +relaxed memory ordering is updating counters, such as reference counters because this only +requires atomicity, but neither ordering nor synchronization. +In Metal 3.2 and later, you can use memory_order_seq_cst on atomic_thread_fence to +indicate that everything that happens before a store operation in one thread becomes a visible +side effect in the thread that performs the load, and establishes a single total modification order +of all tagged atomic operations. +6.15.2 Thread Scope +All OS: Metal 3.2 and later support thread_scope for Apple silicon. +The enumeration thread_scope denotes a set of threads for the memory order constraint +that the memory_order provides: +enum thread_scope { +thread_scope_thread, +thread_scope_simdgroup, +thread_scope_threadgroup, +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 268 of 346 + +================================================================================ +=== PAGE 269 === +================================================================================ +thread_scope_device +} +Informally, the thread scope on a synchronization operation defines the set of threads with +which this operation may synchronize, or which may synchronize with the operation. You use it +with atomic_thread_fence. +6.15.3 Fence Functions +All OS: Metal 3.2 and later support atomic_thread_fence for Apple silicon. +The atomic_thread_fence establishes memory synchronization ordering of nonatomic and +relaxed atomic accesses, according to the memory order and thread scope, without an +associated atomic function: +void atomic_thread_fence(mem_flags flags, memory_order order, +thread_scope scope = thread_scope_device) +A fence operates on the following address space scopes: +• threadgroup, if mem_flags include mem_threadgroup +• threadgroup_imageblock, if mem_flags include +mem_threadgroup_imageblock +• object_data, if mem_flags include mem_object_data +• device, if mem_flags include mem_device +• texture, if mem_flags include mem_texture +A fence accepts a scope parameter (see section 6.15.2) that denotes the set of threads for the +fence that the order affects. Depending on the value of order (see section 6.15.1), this +operation: +• has no effects, if order == memory_order_relaxed +• is a sequentially consistent acquire and release fence, if order == +memory_order_seq_cst +An atomic_thread_fence imposes different synchronization constraints than an atomic +store operation with the same memory_order. An atomic store-release operation prevents all +preceding writes from moving past the store-release, and an atomic_thread_fence with +memory_order_seq_cst ordering prevents all preceding writes from moving past all +subsequent stores within that scope. +6.15.4 Atomic Functions +In addition, accesses to atomic objects may establish interthread synchronization and order +nonatomic memory accesses as specified by memory_order. +In the atomic functions described in the subsections of this section: +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 269 of 346 + +================================================================================ +=== PAGE 270 === +================================================================================ +• A refers to one of the atomic types. +• C refers to its corresponding nonatomic type. +• M refers to the type of the other argument for arithmetic operations.

Barriers encoded in +an ICB do not affect the parent encoder. +The CPU may have initialized individual commands within a command_buffer before the +command_buffer is passed as an argument to a shader. If the CPU has not already initialized +a command, you must reset that command before using it. +6.16.3 Copying Commands of an Indirect Command Buffer +Copying a command structure (either render_command or compute_command) via +operator= does not copy the content of the command, it only makes the destination +command point to the same buffer and index as the source command. To copy the content of +the command, call the copy_command functions listed in sections 6.16.1 and 6.16.2. +Copying is only supported between commands pointing to compatible command buffers. Two +command buffers are compatible only if they have matching ICB descriptors +(MTLIndirectCommandBufferDescriptor objects). The commands themselves must also +refer to valid indexes within the buffers. The following example illustrates using +copy_command to copy the content of a render command from cmd0 to cmd1: +struct arguments { +command_buffer cmd_buffer; +render_pipeline_state pipeline_state_0; +render_pipeline_state pipeline_state_1; +}; +[[kernel]] void producer(device arguments &args) { +render_command cmd0(args.cmd_buffer, 0); +render_command cmd1(args.cmd_buffer, 1); +cmd0.set_render_pipeline_state(args.pipeline_state_0); +// Make the command at index 1 point to command at index 0. +cmd1 = cmd0; +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 283 of 346 + +================================================================================ +=== PAGE 284 === +================================================================================ +// Change the pipeline state for the command at index 0 in the +// buffer. +cmd1.set_render_pipeline_state(args.pipeline_state_0); +// The command at index 1 in the buffer is not yet modified. +cmd1 = render_command(args.cmd_buffer, 1); +// Copy the content of the command at index 0 to command at +// index 1. +cmd1.copy_command(cmd0); +} +6.17 Variable Rasterization Rate +iOS: Metal 2.2 and later support variable rasterization rate and the rasterization rate map. +macOS: Metal 2.3 and later support variable rasterization rate and the rasterization rate map. +Variable rasterization rate (VRR) can reduce the shading cost of high-resolution rendering by +reducing the fragment shader invocation rate based on screen position. VRR is especially useful +to avoid oversampling peripheral information in Augmented Reality (AR) / Virtual Reality (VR) +applications. +To support VRR in a shading language function, use the +rasterization_rate_map_decoder structure to describe the mapping of per-layer +rasterization rate data. Each layer contains minimum quality values in screen space and can +have a different physical fragment space dimension. For AR/VR, these quality values are based +on the lens transform or eye-tracking information. +struct rasterization_rate_map_data; +struct rasterization_rate_map_decoder { +explicit rasterization_rate_map_decoder( +constant rasterization_rate_map_data &data) thread; +float2 map_screen_to_physical_coordinates(float2 screen_coordinates, +uint layer_index = 0) const thread; +uint2 map_screen_to_physical_coordinates(uint2 screen_coordinates, +uint layer_index = 0) const thread; +float2 map_physical_to_screen_coordinates(float2 physical_coordinates, +uint layer_index = 0) const thread; +uint2 map_physical_to_screen_coordinates(uint2 physical_coordinates, +uint layer_index = 0) const thread; +}; +The VRR map describes the mapping between screen space and physical fragment space and +enables conversion of the rendering results back to the desired screen resolution. To convert +between screen space and physical fragment space in the shader, the app must call the +copyParameterDataToBuffer:offset: method of MTLRasterizationRateMap to fill +the buffer with map data before using any of the conversion functions in the +rasterization_rate_map_decoder structure. Passing anything other than a pointer to +2025-10-23 | Copyright © 2025 Apple Inc. | All Rights Reserved. +Page 284 of 346 + +================================================================================ +=== PAGE 285 === +================================================================================ +the data exported by the copyParameterDataToBuffer:offset: method has an +undefined behavior. +The following example shows how the app must pass the rasterization_rate_map_data +at the shader bind point to the constructor of the rasterization_rate_map_decoder +structure: +[[fragment]] float4 fragment_shader(/* other arguments */ +constant rasterization_rate_map_data &data [[buffer(0)]]) { +float2 screen_coords = ...; +rasterization_rate_map_decoder map(data); +float2 physical_coords = +map.map_screen_to_physical_coordinates(screen_coords); +... +} +Alternately, the app can compute the offset where the compiled data is stored and use an +explicit cast or pointer arithmetic to form the data for a valid +rasterization_rate_map_data. Since rasterization_rate_map_data is an +incomplete type, some operations on it are inherently forbidden (such as pointer arithmetic on +the pointer type or sizeof). +6.18 Ray-Tracing Functions +All OS: Metal 2.3 and later support ray-tracing functions. +Metal defines the ray-tracing functions and types in in the namespace +metal::raytracing.

The header defines these functions within the namespace mpp. +The tensor +_ops namespace, which resides beneath the mpp namespace, contains functions +that operate on tensors, including matrix multiplication and convolution. The functions that +operate on tensor. Tensor Operations (TensorOps), use tensor and cooperative_tensors +(see section 2.21) and have been tuned for Apple silicon GPUs. For a list of supported GPU +families, refer to the Metal Feature Set Tables at developer.apple.com. When instantiating a +TensorOp, you pass the scope of execution for the operation, where scope is the number of +threads cooperating to execute the operation (see section 7.1). +7.1 Execution Scopes +All OS: Metal 4 and later support execution scopes. +Operations like TensorOps can work on a single thread, or cooperatively across threads in a +SIMD-group or multiple SIMD-groups.

TensorOps are class templates that you +instantiate with a set of properties, including the execution scope, to indicate if the operation +should run on a single thread or cooperatively across threads in a SIMD-group or multiple +SIMD-groups (see section 7.1). When calling the TensorOp run method, all threads must call +the method within that scope, or the result is undefined. For example, if the scope used to +create the TensorOp is execution_simdgroup, you must ensure all threads within the same +SIMD-group call the run method. Note that different SIMD-groups can be divergent with each +other in this case. +TensorOps may use a barrier at the level of the execution scope. For example, if you specify the +scope of an operation to be the entire threadgroup, you should ensure your code would behave +correctly if a barrier is used in the TensorOp implementation. +If the TensorOps writes the result into a tensor whose ElementType is in device or +threadgroup address space, you must insert a barrier (see section 6.9.1) at the appropriate +thread scope and set the appropriate memory flags before reading the results. You don’t need +to use a barrier for tensors whose memory is in thread address space or for +cooperative_tensors. For example, if the TensorOp run method writes to a tensor whose +ElementType is in threadgroup memory and scope is execution_simdgroups<2>, call +threadgroup_barrier(mem_flags::mem_threadgroup) before reading the result of +the tensor. Another example is if the TensorOp run method writes to a tensor whose +ElementType is in device memory and scope is execution_simdgroup, call +simdgroup_barrier(mem_flags::mem_device) before reading the result of the tensor. +Table 7.2 TensorOps +TensorOp template classes Description +template < +matmul2d_descriptor Desc, +typename Scope, +class...

Use the “round ties to even” or “round toward zero” rounding mode for +conversions from a floating-point or integer type to a floating-point type. +The conversions from half and bfloat to float are lossless. Conversions from float to +half or to bfloat round the mantissa using the round ties to even rounding mode. When +converting a float to a half, denormalized numbers generated for the half data type may +not be flushed to zero. +When converting a floating-point type to an integer type, if the floating-point value is NaN, the +resulting integer is 0. +Note that fast math does not change the accuracy of conversion operations. +8.7 Texture Addressing and Conversion Rules +The texture coordinates specified to the sample, sample_compare, gather, +gather_compare, read, and write functions cannot be INF or NaN. An out-of-bound +texture read returns the default value for each component, as described in section 6.12, and +Metal ignores an out-of-bound texture write. +The following sections discuss the application of conversion rules when reading and writing +textures in a graphics or kernel function.

There is no sign bit. The 10- and 11-bit floating-point types preserve +denormalizes. +These floating-point formats use the following rules: +• If the exponent and mantissa are 0, the floating-point value is 0.0. +• If the exponent is 31 and the mantissa is != 0, the resulting floating-point value is a NaN. +• If the exponent is 31 and the mantissa is 0, the resulting floating-point value is positive +infinity. +• If 0 <= exponent <= 31, the floating-point value is 2 ^ (exponent - 15) * (1 + mantissa/N). +• If the exponent is 0 and the mantissa is != 0, the floating-point value is a denormalized +number given as 2 ^ (exponent – 14) * (mantissa / N).
