13 daysfeat: register math/color_c64 snippet in ShaderComposerskal
2026-03-08fix: register debug/debug_print snippet in ShaderComposerskal
Add SHADER_DEBUG_DEBUG_PRINT to assets.txt and register it as "debug/debug_print" in InitShaderComposer() so ntsc.wgsl #include works. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
2026-03-07feat(effects): add Ntsc post-process effect with fisheye distortionskal
WGSL-only WgslEffect implementing barrel/fisheye distortion, RGB chroma separation, scanlines, per-pixel temporal noise, rolling jitter line, vignette, and warm NTSC phosphor tint. Applied across all main sequences. handoff(Gemini): Ntsc effect added; 13 effects total, 35+1 tests expected. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
2026-03-06feat(effects): add Scratch post-process effect with reusable scratch_lines ↵skal
snippet - src/shaders/render/scratch_lines.wgsl: reusable WGSL snippet registered as "render/scratch_lines"; call scratch_lines(uv, resolution, time)->f32 from any effect. Uses hash_1f from math/noise; 8 lines/frame, ~24fps flicker. - src/effects/scratch.{wgsl,h,cc}: thin Scratch effect wrapping the snippet. - Applied to "intro" and "rotating_cube" sequences as the final step. - 35/35 tests passing. handoff(Gemini): Scratch effect added. render/scratch_lines snippet is reusable.

2026-02-28fix(tools/shadertoy): fix Next Steps instructions and update EFFECT_WORKFLOW.mdskal
- 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>
2026-02-28fix(shaders): deduplicate VertexOutput/vs_main via render/fullscreen_uv_vs ↵skal
snippet - Fix vs_main return type (VertexOutput, not vec4<f32>) - Fix #include paths in passthrough, gaussian_blur, heptagon, combined_postprocess - ShaderComposer: assert + suggest correct path on missing #include (non-STRIP_ALL) - VerifyIncludes: upgrade WARNING to ERROR + assert, add "did you mean?" hint Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
2026-02-21split raymarching.wgsl in two: with id, or without id.skal
2026-02-20feat(scene1): replace ad-hoc camera with CameraParams uniformskal
Build camera via mat4::look_at + inverse in scene1_effect.cc, upload as CameraParams at binding 3. Shader uses getCameraRay() from camera_common. Enable camera_common snippet registration in shaders.cc. handoff(Claude): Scene1 camera now driven by CameraParams uniform; fov=TAU/6 (60° vFOV) matches original tan(PI/3) parameterization.

2026-02-20feat(sequence): port Scene1Effect + fix seq_compiler absolute time bugskal
- Add Scene1 effect: raymarching cube+sphere+ground (reflections, shadows) - Fix scene1.wgsl: binding 0→2, CommonUniforms→UniformsSequenceParams - Replace Heptagon+Placeholder stub in heptagon_scene with Scene1 - Fix seq_compiler.py: emit seq.start_time+effect.start/end (absolute times) so dispatch_render active check works correctly for all sequences Bug: effects in sequences starting after t=0 were never active because local times (e.g. 0-8) never satisfied params.time<end for absolute time 20+. 34/34 tests passing. handoff(Gemini): seq_compiler now emits absolute effect times. All existing sequences affected — verify visual output across the full timeline. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
2026-02-17style: Apply clang-formatskal
2026-02-17refactor: move shaders.{h,cc} to src/effects and remove v2 suffixskal
- Removed unused v1 shader declarations (13 variables) - Removed _v2 suffix from active shader names - Moved shaders.{h,cc} from src/gpu to src/effects - Updated all includes and build references - All tests pass (34/34) handoff(Claude): Cleaned up shader management, tests passing
