From 225ff0313c5021c3f1ec2bf5dd61114032b925a7 Mon Sep 17 00:00:00 2001 From: skal Date: Tue, 10 Feb 2026 18:19:30 +0100 Subject: feat: Add Scene1 effect from ShaderToy (raymarching cube & sphere) Converted ShaderToy shader (Saturday cubism experiment) to Scene1Effect following EFFECT_WORKFLOW.md automation guidelines. **Changes:** - Created Scene1Effect (.h, .cc) as scene effect (not post-process) - Converted GLSL to WGSL with manual fixes: - Replaced RESOLUTION/iTime with uniforms.resolution/time - Fixed const expressions (normalize not allowed in const) - Converted mainImage() to fs_main() return value - Manual matrix rotation for scene transformation - Added shader asset to workspaces/main/assets.txt - Registered in CMakeLists.txt (both GPU_SOURCES sections) - Added to demo_effects.h and shaders declarations - Added to timeline.seq at 22.5s for 10s duration - Added to test_demo_effects.cc scene_effects list **Shader features:** - Raymarching cube and sphere with ground plane - Reflections and soft shadows - Sky rendering with sun and horizon glow - ACES tonemapping and sRGB output - Time-based rotation animation **Tests:** All effects tests passing (5/9 scene, 9/9 post-process) Co-Authored-By: Claude Sonnet 4.5 --- src/gpu/effects/shaders.h | 1 + 1 file changed, 1 insertion(+) (limited to 'src/gpu/effects/shaders.h') diff --git a/src/gpu/effects/shaders.h b/src/gpu/effects/shaders.h index 7acc2a6..03fa48c 100644 --- a/src/gpu/effects/shaders.h +++ b/src/gpu/effects/shaders.h @@ -15,6 +15,7 @@ extern const char* ellipse_shader_wgsl; extern const char* particle_spray_compute_wgsl; extern const char* gaussian_blur_shader_wgsl; extern const char* solarize_shader_wgsl; +extern const char* scene1_shader_wgsl; extern const char* distort_shader_wgsl; extern const char* chroma_aberration_shader_wgsl; extern const char* vignette_shader_wgsl; -- cgit v1.2.3
