- Fix assets.txt path: shaders/xxx.wgsl (not ../../src/shaders/) - Fix shader output path to workspaces/main/shaders/ - Step 5: reference cmake/DemoSourceLists.cmake COMMON_GPU_EFFECTS (not CMakeLists.txt GPU_SOURCES) - Add step for test_demo_effects.cc Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
2026-02-28misc: cleanup comments and formatting in headersskal
- asset_manager_dcl.h: clarify purpose vs asset_manager.h - camera_params.h: broaden description to include 3D rendering - sdf_cpu.h: simplify calc_normal formatting - platform.h: add missing newline at EOF Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
2026-02-28refactor(gpu): move RenderPipelineBuilder impl to pipeline_builder.ccskal
Keeps .h as declarations only; moves all method bodies to .cc. Adds pipeline_builder.cc to COMMON_GPU_EFFECTS in DemoSourceLists.cmake. handoff(Claude): pipeline_builder split to .h/.cc, builds clean.
2026-02-28refactor(gpu): move SamplerCache impl to .cc, expose single entry pointskal
get_or_create() and clear() moved out of the header-only class. SamplerSpec and presets remain inline (trivial, no deps). handoff(Gemini): sampler_cache split into .h/.cc, sampler_cache.cc added to COMMON_GPU_EFFECTS. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
2026-02-28remove SDFEffect base class and sdf_test, update SDF_EFFECT_GUIDEskal
- Delete unused SDFEffect base class (src/gpu/sdf_effect.h) - Delete sdf_test.wgsl and SHADER_SDF_TEST from assets.txt - Rewrite SDF_EFFECT_GUIDE.md based on Scene1 canonical pattern: correct bindings (2/3), vec4f syntax, UniformsSequenceParams - Fix missing newline at end of gpu.h handoff(Claude): SDF cleanup done, guide updated to match current Effect API
2026-02-28remove vestigial demo_effects.ccskal
handoff(Gemini): deleted src/gpu/demo_effects.cc (empty stub), removed from headless GPU_SOURCES in DemoSourceLists.cmake, dropped stale #include from post_process_helper.cc. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
2026-02-28fix: double-free of external views in NodeRegistry and PASSTHROUGH shader testskal
- NodeRegistry: skip external nodes (texture==nullptr) in ~NodeRegistry() and resize() to avoid double-releasing views set via set_external_view() - test_shader_assets: update PASSTHROUGH check to match #include pattern handoff(Claude): 35/35 tests passing. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
2026-02-28fix(shaders): deduplicate VertexOutput/vs_main via render/fullscreen_uv_vs ↵skal

All existing sequences affected — verify visual output across the full timeline. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
2026-02-17feat(uniforms): Add noise field with per-frame random valuesskal

Reduces boilerplate in effect destructors and prevents resource leaks. - set() for one-time initialization - replace() for per-frame recreation - Field ordering documented for dependency management Converted 3 effects (Heptagon, Flash, Passthrough) and Effect base class. All tests pass (34/34). Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
2026-02-17refactor(effects): Factor shared initialization into Effect base classskal
Eliminate ~100 lines of duplicated code across effect subclasses by moving common resource initialization to the base Effect class. Most effects repeatedly created uniforms buffers, samplers, and dummy textures with identical configurations. Changes: - Add shared members to Effect: uniforms_buffer_, sampler_, dummy_texture_* - Add helpers: init_uniforms_buffer(), create_*_sampler(), create_dummy_scene_texture() - Add gpu_create_*_sampler() and gpu_create_dummy_scene_texture() to gpu.h - Move HEADLESS_RETURN_IF_NULL to Effect constructor - Update 7 effects to use base class helpers (Flash, Heptagon, Passthrough, Placeholder, GaussianBlur, Particles, PeakMeter) Benefits: Improved consistency, easier maintenance, reduced binary size. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
2026-02-17docs(gpu): Purge comment bloat from GPU headersskal

2026-02-17refactor(gpu): Remove stale v2 references from demo_effectsskal
Removed outdated comments referencing old naming conventions and non-existent functions. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
2026-02-17fix(build): Resolve Windows cross-compilation failuresskal
This commit fixes several issues that caused the Windows cross-compilation build (`scripts/build_win.sh`) to fail. The root causes were platform-specific API differences in the wgpu-native library and incorrect dependency tracking in the CMake build system for generated code. Changes: - **`tools/seq_compiler.py`**: The timeline generator now wraps `depthSlice` assignments in `#if !defined(DEMO_CROSS_COMPILE_WIN32)` directives to handle API differences in `WGPURenderPassColorAttachment`. - **`src/gpu/gpu.h`**: The `gpu_init_color_attachment` helper is now platform-aware, using a preprocessor guard for the `depthSlice` member. - **`src/effects/*.cc`**: All effects are updated to use the new platform-aware helper or have explicit guards for `depthSlice`. Also, replaced `WGPUTexelCopyTextureInfo` with the cross-platform alias `GpuTextureCopyInfo` in `rotating_cube_effect.cc`. - **`cmake`**: Added `tools/seq_compiler.py` as an explicit dependency to the `generate_timeline` and `generate_test_demo_timeline` custom commands. This ensures that changes to the generator script correctly trigger a rebuild of the generated C++ files. - **`scripts/build_win.sh`**: Removed the erroneous attempt to build the `seq_compiler.py` script as a native executable. With these changes, the Windows cross-compilation build now completes successfully.

2026-02-17feat: add time-based effect activation with auto-passthroughskal
Effects now accept start/end time parameters and automatically passthrough when inactive. Implements buffer chain integrity via compile-time validation. - Effect base class: dispatch_render() checks time bounds, auto-passthroughs 1:1 input/output effects outside [start, end] interval - seq_compiler.py: validates producer/consumer lifespan constraints for multi-output effects, adds --validate flag, always validates before codegen - Updated all 9 effect classes and test fixtures to pass start/end times - check_all.sh: includes timeline validation step - Tests: 34/34 passing, demo runs successfully Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

2026-02-16feat: Add PeakMeterEffect v2 for test_demo audio visualizationskal
