three-js

This skill should be used when the user asks to "create a 3D scene", "add a mesh", "implement OrbitControls", "load a GLTF model", "add bloom post-processing", "write a custom shader", "create particle effects", "optimize Three.js performance", "use WebGPU", "add shadows", "animate a model", or mentions Three.js, threejs, WebGL, WebGPU, GLTF, raycaster, shader material, PBR material, or post-processing effects.

IMPORTANT: This skill is for VANILLA Three.js (imperative JavaScript). For React Three Fiber (@react-three/fiber, R3F, drei), check the r3f-best-practices skill, although three-js skills helps when working with R3F since R3F is a React renderer for Three.js.

Provides complete Three.js reference for 3D web graphics including scene setup, geometry, materials, textures, lighting, cameras, loaders, animation, controls, interaction, shaders, post-processing, performance optimization, TSL/node materials, WebGPU, physics, and VR/XR integration.
