See `doc/DEBUG_SHADOWS.md`.) - - [x] **Task A.2**: Investigate and fix ObjectType::PLANE with non-uniform scaling (Fixed: Implemented correct scaling factor for planes in map_scene and PhysicsSystem). - -- [ ] **Task B: Move platform-specific conditional code into a single header location** - - [ ] Abstract out `#if defined(DEMO_CROSS_COMPILE_WIN32)` statements from core `.cc` and `.h` sources. - - [ ] Centralize platform-specific code and `#ifdef`s into `platform.h` or equivalent. - - [ ] Address `str_view()` calls that cause compilation breaks. ## Priority 1: Spectral Brush Editor (Task #5) [IN PROGRESS] @@ -91,30 +78,13 @@ This file tracks prioritized tasks with detailed attack plans. ## Priority 2: 3D System Enhancements (Task #18) **Goal:** Establish a pipeline for importing complex 3D scenes to replace hardcoded geometry. -- [x] **Task #18.0: Basic OBJ Asset Pipeline** (New) - - [x] Define `ASSET_MESH` type in `asset_manager`. - - [x] Update `asset_packer` to parse simple `.obj` files (positions, normals, UVs) and serialize them. - - [x] Update `Renderer3D` to handle `ObjectType::MESH` in the rasterization path. -- [x] **Task #36: Blender Exporter:** Create a Python script (`tools/blender_export.py`) to export meshes/cameras/lights to a binary asset format. -- [x] **Task #37: Asset Ingestion:** Update `asset_packer` to handle the new 3D binary format. - - [x] **Task #38: Runtime Loader:** Implement a minimal C++ parser to load the scene data into the ECS/Renderer. -- [x] **Task #18-B: GPU BVH & Shadows** (Optimization) - - [x] **Upload BVH:** Create a storage buffer for `BVHNode` data and upload the CPU-built BVH every frame in `Renderer3D`. - - [x] **Shader Traversal:** Implement stack-based BVH traversal in `scene_query.wgsl` to replace the linear loop in `map_scene`. - - [x] **Shadow Optimization:** Use the BVH traversal for `calc_shadow` to skip occluded objects efficiently. - - [x] **Compile-Time Switch:** Implemented dual-pipeline architecture (BVH vs Linear) using `ShaderComposer` substitution to avoid runtime branching cost. ## Priority 3: WGSL Modularization (Task #50) [RECURRENT] **Goal**: Refactor `ShaderComposer` and WGSL assets to support granular, reusable snippets and `#include` directives.
