React Three Fiber
React renderer for Three.js. Declaratively create Three.js scene graphs using React's JSX syntax and component model. Three.js cameras, meshes, lights, and materials become React components. State management, animations, and interactivity use React hooks and the Zustand/Jotai patterns. Companion library @react-three/drei provides 150+ helpers (OrbitControls, Loader, Environment, etc.). Developed by Paul Henschel (poimandres) and widely used for React 3D experiences.

🔒 Security
Client-side WebGL rendering — no network communication in the library. MIT licensed. PMndrs ecosystem is widely used and reviewed.
⚡ Reliability
Best When
You're building 3D experiences in a React application and want declarative, component-based scene management with React hooks for state and interactivity.
Avoid When
Maximum WebGL performance is critical (game engines, heavy simulations) — the React reconciler adds overhead vs direct Three.js imperative code.
Use Cases
- • Build 3D scenes declaratively in React using JSX — <mesh>, <boxGeometry>, <meshStandardMaterial> as React components
- • Create interactive 3D product views, hero animations, and portfolio pieces in React applications
- • Use @react-three/drei helpers (OrbitControls, useGLTF, Environment, Text3D) for rapid 3D UI development
- • Combine Three.js 3D rendering with React's UI components for applications mixing 2D UI and 3D views
- • Build React Native 3D experiences using @react-three/fiber's React Native target with expo-gl
Not For
- • Pure Three.js performance tuning — React's reconciler adds overhead; use Three.js directly for performance-critical scenes
- • Teams not using React — Three.js directly or other framework bindings are more appropriate
- • Simple static 3D models — React Three Fiber overhead isn't justified for static GLTF display; use model-viewer web component
Interface
Authentication

Agent Metadata
Known Gotchas
- ⚠ React Three Fiber uses Three.js under the hood — understanding Three.js concepts (scene graph, materials, geometries) is required; R3F doesn't abstract these away
- ⚠ The useFrame hook runs on every animation frame — expensive operations in useFrame cause frame drops; use refs and avoid React state in frame loops
- ⚠ Memory management still required — call dispose() on geometries and materials when components unmount, or use @react-three/drei's useGLTF disposal helpers
- ⚠ @react-three/drei is a separate package but nearly always needed — R3F alone requires implementing many common helpers from scratch
- ⚠ React Suspense is used for asset loading (useGLTF, useTexture) — must wrap 3D components in Suspense with fallback for loading states
- ⚠ TypeScript types require @types/three for correct Three.js type augmentation — missing types cause property access errors
