Threejs

This is a comprehensive Three.js reference that covers the full scope of building 3D web experiences, from basic scene setup through advanced topics like custom shaders and postprocessing. It's organized into 10 domain-specific files you load based on what you're working on, whether that's PBR materials, GLTF animation mixing, or raycasting for mouse interaction. The examples are current to Three.js r160+ and include practical patterns like proper shadow configuration, instanced meshes for performance, and responsive camera handling. If you're doing any WebGL work beyond trivial demos, this gives you accurate API references and working code without having to dig through Three.js docs mid-conversation.
