Shader Dev

A deep collection of 36 GLSL techniques organized as a routing table that maps what you want (fluid sim, raymarched scenes, particle effects) to specific implementation files. Each technique file includes core principles, complete code templates, and links to reference docs with the math. Built for ShaderToy-style fragment shaders with WebGL2 adaptation rules included. The routing approach is smart: instead of searching through docs, you match the user's request ("create soft shadows on an SDF scene") to the table and pull exactly the techniques you need. Covers everything from basic 2D SDFs to path tracing and reaction-diffusion systems. Honestly more of a shader encyclopedia than a narrow skill, which makes it useful as a reference but requires you to actually understand what techniques combine well.
