Implement Procedural Texture system (Task #3 -> #1): + - `src/procedural/` module (Done). + - Integration with WebGPU: Generate textures at runtime and upload to GPU (Done). + - `src/gpu/texture_manager` implemented and tested. +- 14. Implement 3D system (Task #1 -> #2): + - `src/3d/` module (math, camera, scene, renderer) (Done). + - `Renderer3D` implemented with basic cube rendering (Done). + - `test_3d_render` mini-demo created (Debugging crash in `wgpuInstanceWaitAny`). +- 15. Shader Logic (Task #2 -> #3): + - Ray-object intersection & SDF rendering in WGSL. ## Session Decisions and Current State +### 3D Renderer Implementation +- **Renderer3D**: Encapsulates pipeline creation and render pass recording. +- **Shader**: Currently uses a simple vertex/fragment shader for cubes. +- **Storage**: Objects are stored in a `StorageBuffer` (instance data). +- **Test Tool**: `test_3d_render` created to isolate 3D development. +- **Issue**: `test_3d_render` crashes with "not implemented" in `wgpuInstanceWaitAny` on macOS. + +### Procedural Textures +- **TextureManager**: Handles CPU generation -> GPU upload. +- **API**: Supports `WGPUTexelCopyTextureInfo` (new API) with fallback macros for older headers. + ### Sequence & Effect System - **Architecture**: Implemented a hierarchical sequencing system. - **Effect**: Abstract base for visual elements. Supports `compute` (physics) and `render` (draw) phases. Idempotent `init` for shared asset loading. |
