From aab1dc237e6669debb76412fd95f8519caaee54e Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 23 Feb 2026 11:50:50 +0000 Subject: [PATCH 1/3] feat: implement Phase 5 scene graph and object placement Adds SceneNode/Quadtree/SceneGraph spatial indexing infrastructure and ObjectNode/ObjectResolver/ObjectPlacementUtils for placing W3D models at map object positions with correct coordinate-system conversion. - SceneNode: base class with position/rotationY/scale transforms, local and world bounding boxes, visibility flag, and worldTransform() matrix - Quadtree: 2D spatial index in X/Z plane with frustum and rect queries; center-based single-child insertion avoids duplicate query results; subdivide() accesses nodes by index (not reference) to avoid UB from vector reallocation during push_back - SceneGraph: owns SceneNodes, maintains Quadtree, provides queryVisible() for frustum-culled queries and queryAll() for full iteration - ObjectNode: SceneNode subclass wrapping HLodModel* with templated draw() composing worldTransform with per-bone transforms; fromMapObject() factory - ObjectPlacementUtils: Vulkan-free static utilities (templateNameToW3DName, mapPositionToVulkan Z-up->Y-up, isRoadPoint, isBridgePoint, shouldRender) - ObjectResolver: caches loaded HLodModels by template name; resolve() looks up W3D path via AssetRegistry, extracts from BIG archive, parses and caches - 47 new tests (scene_tests + object_resolver_tests); 100% pass rate https://claude.ai/code/session_01JKxTAtdKkNECTCaiVV5Ywz --- src/lib/scene/quadtree.cpp | 171 ++++++++++++++++++++++++++ src/lib/scene/quadtree.hpp | 64 ++++++++++ src/lib/scene/scene_graph.cpp | 38 ++++++ src/lib/scene/scene_graph.hpp | 35 ++++++ src/lib/scene/scene_node.cpp | 59 +++++++++ src/lib/scene/scene_node.hpp | 45 +++++++ src/render/object_node.cpp | 22 ++++ src/render/object_node.hpp | 56 +++++++++ src/render/object_placement_utils.cpp | 41 ++++++ src/render/object_placement_utils.hpp | 21 ++++ src/render/object_resolver.cpp | 71 +++++++++++ src/render/object_resolver.hpp | 71 +++++++++++ tests/CMakeLists.txt | 39 ++++++ tests/scene/test_object_resolver.cpp | 77 ++++++++++++ tests/scene/test_quadtree.cpp | 149 ++++++++++++++++++++++ tests/scene/test_scene_graph.cpp | 154 +++++++++++++++++++++++ tests/scene/test_scene_node.cpp | 139 +++++++++++++++++++++ 17 files changed, 1252 insertions(+) create mode 100644 src/lib/scene/quadtree.cpp create mode 100644 src/lib/scene/quadtree.hpp create mode 100644 src/lib/scene/scene_graph.cpp create mode 100644 src/lib/scene/scene_graph.hpp create mode 100644 src/lib/scene/scene_node.cpp create mode 100644 src/lib/scene/scene_node.hpp create mode 100644 src/render/object_node.cpp create mode 100644 src/render/object_node.hpp create mode 100644 src/render/object_placement_utils.cpp create mode 100644 src/render/object_placement_utils.hpp create mode 100644 src/render/object_resolver.cpp create mode 100644 src/render/object_resolver.hpp create mode 100644 tests/scene/test_object_resolver.cpp create mode 100644 tests/scene/test_quadtree.cpp create mode 100644 tests/scene/test_scene_graph.cpp create mode 100644 tests/scene/test_scene_node.cpp diff --git a/src/lib/scene/quadtree.cpp b/src/lib/scene/quadtree.cpp new file mode 100644 index 0000000..220dc2c --- /dev/null +++ b/src/lib/scene/quadtree.cpp @@ -0,0 +1,171 @@ +#include "quadtree.hpp" + +#include + +namespace w3d::scene { + +Quadtree::Quadtree(float minX, float minZ, float maxX, float maxZ, int maxDepth, int maxPerNode) + : maxDepth_(maxDepth), maxPerNode_(maxPerNode) { + Node root;

Pass depth through to subdivide() and use it when calling insertInto() to preserve correct tree depth. - Fix MapObject::shouldRender() to exclude road/bridge points, aligning it with ObjectPlacementUtils::shouldRender(). Road/bridge points are placement markers, not renderable models, so both call sites now agree. - Add regression test SubdivisionDepthIsTrackedCorrectly to verify that multi-level subdivision respects maxDepth limits. https://claude.ai/code/session_01JKxTAtdKkNECTCaiVV5Ywz --- src/lib/formats/map/types.hpp | 4 +++- src/lib/scene/quadtree.cpp | 6 +++--- src/lib/scene/quadtree.hpp | 2 +- tests/scene/test_quadtree.cpp | 25 +++++++++++++++++++++++++ 4 files changed, 32 insertions(+), 5 deletions(-) diff --git a/src/lib/formats/map/types.hpp b/src/lib/formats/map/types.hpp index ff9b9a8..dd5bc45 100644 --- a/src/lib/formats/map/types.hpp +++ b/src/lib/formats/map/types.hpp @@ -129,7 +129,9 @@ struct MapObject { bool isBridgePoint() const { return (flags & (FLAG_BRIDGE_POINT1 | FLAG_BRIDGE_POINT2)) != 0; } - bool shouldRender() const { return (flags & FLAG_DONT_RENDER) == 0; } + bool shouldRender() const { + return (flags & FLAG_DONT_RENDER) == 0 && !isRoadPoint() && !isBridgePoint(); + } }; struct PolygonTrigger { diff --git a/src/lib/scene/quadtree.cpp b/src/lib/scene/quadtree.cpp index 4cf6aa7..1148151 100644 --- a/src/lib/scene/quadtree.cpp +++ b/src/lib/scene/quadtree.cpp @@ -35,7 +35,7 @@ void Quadtree::insertInto(int nodeIndex, const Entry &entry, int depth) { if (n.isLeaf) { n.entries.push_back(entry); if (static_cast(n.entries.size()) > maxPerNode_ && depth < maxDepth_) { - subdivide(nodeIndex); + subdivide(nodeIndex, depth); } return; } @@ -62,7 +62,7 @@ void Quadtree::insertInto(int nodeIndex, const Entry &entry, int depth) { } } -void Quadtree::subdivide(int nodeIndex) { +void Quadtree::subdivide(int nodeIndex, int depth) { float midX = (nodes_[nodeIndex].bounds.minX + nodes_[nodeIndex].bounds.maxX) * 0.5f; float midZ = (nodes_[nodeIndex].bounds.minZ + nodes_[nodeIndex].bounds.maxZ) * 0.5f; @@ -91,7 +91,7 @@ void Quadtree::subdivide(int nodeIndex) { nodes_[nodeIndex].entries.clear(); for (const auto &entry : entries) { - insertInto(nodeIndex, entry, 1); + insertInto(nodeIndex, entry, depth); } } diff --git a/src/lib/scene/quadtree.hpp b/src/lib/scene/quadtree.hpp index b33f863..bcaf9db 100644 --- a/src/lib/scene/quadtree.hpp +++ b/src/lib/scene/quadtree.hpp @@ -48,7 +48,7 @@ class Quadtree { [[nodiscard]] Rect nodeWorldRect(const SceneNode *node) const; void insertInto(int nodeIndex, const Entry &entry, int depth); - void subdivide(int nodeIndex); + void subdivide(int nodeIndex, int depth); void queryNode(int nodeIndex, const Rect &rect, std::vector &result) const; void queryNodeFrustum(int nodeIndex, const gfx::Frustum &frustum, std::vector &result) const; diff --git a/tests/scene/test_quadtree.cpp b/tests/scene/test_quadtree.cpp index 5c0cac0..2b5ab19 100644 --- a/tests/scene/test_quadtree.cpp +++ b/tests/scene/test_quadtree.cpp @@ -139,6 +139,31 @@ TEST_F(QuadtreeTest, ManyNodesCanBeInserted) { EXPECT_EQ(result.size(), 100u); } +// Regression test: verifies that depth tracking is correct across multiple levels of +// subdivision.
