Conversation
- Deleted renderer.cpp and renderer.h files, removing the OpenGL renderer for Gaussian splatting. - Removed shader.h file, which contained shader compilation and management code. - Updated viewer_ui.cpp and viewer_ui.h to eliminate dependencies on the removed renderer and camera classes. - Adjusted UI overlay rendering logic to directly manage splat count and rendering parameters without the renderer. - Enhanced UI controls for size scaling, maximum point size, and camera movement speed.
- Introduced `gpu_compute.h` for platform-agnostic GPU compute interfaces. - Implemented `computeCentroidNorms` and `assignPointsToCentroids` functions for both CUDA and Metal. - Added CPU fallback implementations in `kmeans_cpu.cpp`. - Updated `CMakeLists.txt` to conditionally include GPU sources based on selected backend. - Refactored `kmeans.cu` to utilize the new GPU compute functions. - Created Metal compute kernels in `kmeans.metal` and corresponding Metal backend implementation. - Added tests for GPU compute backend functionality in `gpu_compute_test.cpp`. - Ensured proper memory management and error handling in CUDA and Metal implementations.
- Implemented gsplat_data_adapter.h and gsplat_data_adapter.cpp for adapting data tables to GSplat format. - Created gsplat_renderer.h and gsplat_renderer.cpp for rendering GSplat instances using OpenGL. - Added shader sources for vertex and fragment shaders in gsplat_shader_sources.h. - Developed main application logic in main.cpp to handle input files, GLFW window management, and rendering loop. - Introduced tests for data adaptation and camera functionality in playcanvas_viewer_adapter_test.cpp and playcanvas_viewer_camera_test.cpp. - Updated CMakeLists.txt to include new tests and source files.

…zation - Introduced GSplatGLRenderer class for rendering GSplat data using OpenGL. - Added GSplatGLRenderOptions and GSplatGLFrameState structures to manage rendering options and frame state. - Created vertex and fragment shader sources for GSplat rendering. - Updated splat_visualizer to utilize GSplatGLRenderer for rendering. - Implemented functions to compute bounds from GSplat data. - Added tests for GSplat data adapter to ensure correct data adaptation and error handling.
…ctures and remove legacy code
… update PlaycanvasViewerShaderTests configuration
- Removed NativeSplatProp and replaced it with SplatGaussianProp for better encapsulation and functionality. - Updated SplatVisualizer to utilize SplatGaussianProp, ensuring compatibility with existing rendering options. - Added new methods for camera manipulation, including resetCameraToBounds, enhancing user experience. - Introduced unit tests for SplatGaussianProp to validate data handling and rendering options. - Updated smoke tests for SplatVisualizer to verify integration with the new SplatGaussianProp. - Adjusted README and comments to reflect changes in the visualization architecture.
…ructures for GSplat rendering - Deleted legacy files: gsplat_data.h, gsplat_gl_renderer.h, and splat_gaussian_prop.h. - Introduced new gsplat_data.h and gsplat_gl_renderer.h with updated structures and functionalities. - Updated references in various source files to use the new header files. - Enhanced SplatVisualizer with additional mouse wheel interaction options and improved sorting behavior. - Added tests for visualization public headers to ensure proper encapsulation of internal details.

…c_3x3 overload Preparation for area-weighted merge math (#241 follow-up). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Original return-value overload now delegates to the caller-buffer overload instead of duplicating the ~40-line Jacobi algorithm. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
…-weighted mass Memory ~50% lower for cache arrays. Mass now uses ellipsoid surface area instead of volume for better anisotropic handling (#241). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
…e R directly Replaces per-call array allocation with scratch buffer. Switches from Rt-based sampling to R-based sampling (matching upstream GPU kernel). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
