Expert guide for writing efficient GLSL shaders (Vertex/Fragment) for web and game engines, covering syntax, uniforms, and common effects.

When to use

• Use when creating custom visual effects in WebGL, Three.js, or game engines.
• Use when optimizing graphics rendering performance.
• Use when implementing post-processing effects (blur, bloom, color correction).
• Use when procedurally generating textures or geometry on the GPU.

When not to use

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
