shader-dev

# Shader Craft A unified skill covering 36 GLSL shader techniques (ShaderToy-compatible) for real-time visual effects. ## Invocation ``` /shader-dev <request> ``` `$ARGUMENTS` contains the user's request (e.g. "create a raymarched SDF scene with soft shadows"). ## Skill Structure ``` shader-dev/ ├── SKILL.md # Core skill (this file) ├── techniques/ # Implementation guides (read per routing table) │ ├── ray-marching.md # Sphere tracing with SDF │ ├── sdf-3d.md # 3D signed distance functions │ ├── lighting-model.md # PBR, Phong, toon shading │ ├── procedural-noise.md # Perlin, Simplex, FBM │ └── ... # 34 more technique files └── reference/ # Detailed guides (read as needed) ├── ray-marching.md # Math derivations & advanced patterns ├── sdf-3d.md # Extended SDF theory ├── lighting-model.md # Lighting math deep-dive ├── procedural-noise.md # Noise function theory └── ... # 34 more reference files ``` ## How to Use 1. Read the **Technique Routing Table** below to identify which technique(s) match the user's request 2. Read the relevant file(s) from `techniques/` — each file contains core principles, implementation steps, and complete code templates 3. If you need deeper understanding (math derivations, advanced patterns), follow the reference link at the bottom of ...
