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").

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 each technique file to reference/
4. Apply the WebGL2 Adaptation Rules below when generating standalone HTML pages
