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/scene1_effect.h | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) create mode 100644 src/gpu/effects/scene1_effect.h (limited to 'src/gpu/effects/scene1_effect.h') diff --git a/src/gpu/effects/scene1_effect.h b/src/gpu/effects/scene1_effect.h new file mode 100644 index 0000000..dc5c747 --- /dev/null +++ b/src/gpu/effects/scene1_effect.h @@ -0,0 +1,19 @@ +// This file is part of the 64k demo project. +// Scene1 effect - ShaderToy conversion (raymarching scene) + +#ifndef SCENE1_EFFECT_H_ +#define SCENE1_EFFECT_H_ + +#include "gpu/effect.h" + +class Scene1Effect : public Effect { + public: + Scene1Effect(const GpuContext& ctx); + void render(WGPURenderPassEncoder pass, float time, float beat, + float intensity, float aspect_ratio) override; + + private: + RenderPass pass_; +}; + +#endif /* SCENE1_EFFECT_H_ */ -- cgit v1.2.3
