Added a shader validation test to ensure production assets are valid. - **Asset Pipeline Improvement**: Created a robust `gen_spectrograms.sh` script to automate the conversion of `.wav` and `.aif` files to `.spec` format, replacing the old, fragile script. Added 13 new drum and bass samples to the project. - **Build System Consolidation (Task #25)**: Modularized the build by creating subsystem libraries (audio, gpu, 3d, util, procedural) and implemented helper macros to reduce boilerplate in `CMakeLists.txt`. This improves build maintenance and prepares for future CRT replacement. - **Asset System Robustness**: Resolved "static initialization order fiasco" by wrapping the asset table in a "Construct On First Use" getter (`GetAssetRecordTable()`), ensuring assets are available during dynamic global initialization (e.g., shader strings). @@ -3,6 +3,10 @@ This file tracks prioritized tasks with detailed attack plans. ## Recently Completed +- [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()`). diff --git a/assets/final/shaders/test_snippet_a.wgsl b/assets/final/shaders/test_snippet_a.wgsl new file mode 100644 index 0000000..732973d --- /dev/null +++ b/assets/final/shaders/test_snippet_a.wgsl @@ -0,0 +1,4 @@ +// test_snippet_a.wgsl +fn snippet_a() -> f32 { + return 1.0;
