React Three Fiber animation - useFrame, useAnimations, spring physics, keyframes. Use when animating objects, playing GLTF animations, creating procedural motion, or implementing physics-based movement.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# React Three Fiber Animation
## Quick Start
```tsx
import { Canvas, useFrame } from '@react-three/fiber'
import { useRef } from 'react'
function RotatingBox() {
const meshRef = useRef()
useFrame((state, delta) => {
meshRef.current.rotation.x += delta
meshRef.current.rotation.y += delta * 0.5
})
return (
<mesh ref={meshRef}>
<boxGeometry />
<meshStandardMaterial color="hotpink" />
</mesh>
)
}
export default function App() {
return (
<Canvas>
<ambientLight />
<RotatingBox />
</Canvas>
)
}
```
## useFrame Hook
The core animation hook in R3F. Runs every frame.
### Basic Usage
```tsx
import { useFrame } from '@react-three/fiber'
import { useRef } from 'react'
function AnimatedMesh() {
const meshRef = useRef()
useFrame((state, delta) => {
// state contains: clock, camera, scene, gl, mouse, etc.
// delta is time since last frame in seconds
meshRef.current.rotation.y += delta
})
return (
<mesh ref={meshRef}>
<boxGeometry />
<meshStandardMaterial color="orange" />
</mesh>
)
}
```
### State Object
```tsx
useFrame((state, delta, xrFrame) => {
const {

How to install
mdr add zebbern/claude-code-guide/r3f-animation@sha256:7f92c4d4eb453564The line at the top of this page pins the label git:20260531.164971d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
