What problem does it solve?

Three.js developers often need fine-grained custom visuals beyond built-in materials, requiring ShaderMaterial-based shaders and uniforms. This skill provides clear guidance and examples to implement vertex/fragment shaders, manage uniforms, and extend materials for advanced effects.

Core Features & Use Cases

• ShaderMaterial and RawShaderMaterial basics, uniforms management, and GLSL integration
• Common shader techniques: color, textures, displacement, Fresnel, noise, rim lighting, dissolve
• Extending built-in materials via onBeforeCompile and shader chunks
• Instanced shaders, shader includes, and debugging

Quick Start

Follow a minimal example to create a ShaderMaterial with custom vertex/fragment shaders, update time uniform in the animation loop, and apply to a mesh.
