React Three Fiber

React renderer for Three.js

FreeAnimation & motionr3f.docs.pmnd.rs

What it is

Express a 3D scene as JSX instead of imperative Three.js calls, with React state, hooks and Suspense for asset loading. The real draw is the ecosystem: drei (helpers, controls, text), postprocessing, rapier physics, gltfjsx.

Why it earns a slot

Realistic total for a 3D hero: 250–350 kB gz of JS plus model assets. Always lazy-load behind React.lazy so it never touches the initial chunk.

Know before you commit

Version-lock trap: @react-three/fiber@9 requires React >=19 <19.3. Lovable scaffolds commonly sit on React 18.3.x — you need @react-three/fiber@8 on React 18, or upgrade React first.

Getting started

npm install three @react-three/fiber @react-three/drei
