Implemented round-robin slot allocation with proper cleanup. - - [x] **Fixed Note Name Parsing**: Added automatic note-name-to-frequency conversion (E2→82.4Hz, A4→440Hz, etc.) in `tracker_compiler.cc`. Bass and melody now play correctly. - - [x] **Fixed Timing Mismatch**: Patterns are 4 beats (2 seconds at 120 BPM), but SCORE was triggering every 4 seconds. Updated to trigger every 2 seconds for continuous playback. - - [x] **Implemented Dynamic Resource Sizing**: `tracker_compiler` now analyzes scores to determine optimal MAX_VOICES/MAX_SPECTROGRAMS values (max simultaneous patterns: 5, recommended: 10 each). - - [x] **Created Rock Demo Track**: 11 patterns (drums, bass, melody, power chords) with 49 triggers over 25 seconds, using 14 drum samples + 10 procedural notes. - - **Known Issues**: - - Audio playback quality could be improved (some artifacts/cuts remain) - - Note synthesis parameters (duration, harmonics) use default values - need tuning for better sound - - Pattern overlaps might cause voice exhaustion under heavy load - - No dynamic volume/envelope control for melodic notes - -## Recently Completed (Previous) -- [x] **Task #26: Shader Asset Testing & Validation**: - - [x] **Attack Plan - `ShaderComposer` Unit Tests**: Add tests to `test_shader_composer.cc` to verify correct snippet registration, retrieval, and composition for various WGSL shader assets. - - [x] **Attack Plan - Asset Content Validation**: Implement checks (e.g., in `test_assets.cc`) to ensure loaded WGSL shader assets are non-empty and contain expected entry points (`vs_main`, `fs_main`, `main` for compute shaders). - - [x] **Attack Plan - Runtime Shader Validation**: Integrate basic validation steps into the rendering pipeline (e.g., in `gpu.cc`) to log warnings or errors if compiled shader modules are invalid, providing earlier feedback than WebGPU validation errors. -- [x] **Asset Pipeline Improvement**: Automated audio asset conversion with a new `gen_spectrograms.sh` script and added 13 new samples to the asset list. -- [x] **Build System Consolidation (Task #25)**: Modularized the build into subsystem libraries and implemented helper macros to simplify CMake maintenance. -- [x] **Asset System Robustness**: Fixed static initialization order issues by wrapping the asset table in a singleton-style getter (`GetAssetRecordTable()`). -- [x] **Shader Asset Integration (Task #24)**: Extracted hardcoded shaders to `.wgsl` assets, updated `asset_packer` for string safety, and refactored C++ code to use `GetAsset`. -- [x] **WebGPU Stability & macOS Fixes**: Resolved surface creation failures by adding `GLFW_EXPOSE_NATIVE_COCOA` and fixed validation errors in surface configuration and render pass attachments. - ## Priority 1: 3D System Enhancements (Task #18) **Goal:** Establish a pipeline for importing complex 3D scenes to replace hardcoded geometry. - [ ] **Task #36: Blender Exporter:** Create a Python script (`tools/blender_export.py`) to export meshes/cameras/lights to a binary asset format. - [ ] **Task #37: Asset Ingestion:** Update `asset_packer` to handle the new 3D binary format. - [ ] **Task #38: Runtime Loader:** Implement a minimal C++ parser to load the scene data into the ECS/Renderer. -## Priority 2: Developer Tooling & CI +## Priority 2: WGSL Modularization (Task #50) +**Goal**: Refactor `ShaderComposer` and WGSL assets to support granular, reusable snippets and `#include` directives. + +- [ ] **Task #50.1: Recursive Composition Support**: + - [ ] Update `ShaderComposer::Compose` to parse `#include "snippet_name"` directives in shader code. + - [ ] Implement recursive resolution (with cycle detection) to assemble the final shader. + - [ ] Update `test_shader_composer.cc` to verify recursive includes. + +- [ ] **Task #50.2: Granular SDF Library**: + - [ ] Extract `sdSphere`, `sdBox`, `sdTorus`, `sdPlane` from `sdf_primitives.wgsl` into `math/sdf_shapes.wgsl`. + - [ ] Extract `get_normal_basic` into `math/sdf_utils.wgsl`. + - [ ] Extract `calc_shadow` into `render/shadows.wgsl`. + +- [ ] **Task #50.3: Scene & Material Refactor**: + - [ ] Extract `map_scene` and `get_dist` logic into `render/scene_query.wgsl`. + - [ ] Extract lighting and material logic from `fs_main` into `render/lighting_pbr.wgsl` (or similar). + +- [ ] **Task #50.4: Pipeline Update**: + - [ ] Update `Renderer3D` to use the new granular assets via `#include` in the main shader, reducing C++-side dependency lists. + +## Priority 3: Physics & Collision (Task #49) +**Goal**: Implement a lightweight physics engine using SDFs and BVH acceleration.
