react-three-fiber is a React renderer for threejs.
Build your scene declaratively with re-usable, self-contained components that react to state, are readily interactive and can participate in React's ecosystem.
npm install three @types/three @react-three/fiber
None. Everything that works in Threejs will work here without exception.
No. There is no overhead. Components render outside of React. It outperforms Threejs in scale due to React's scheduling abilities.
Yes. It merely expresses Threejs in JSX, <mesh />
dynamically turns into new THREE.Mesh()
. If a new Threejs version adds, removes or changes features, it will be available to you instantly without depending on updates to this library.
Let's make a re-usable component that has its own state, reacts to user-input and participates in the render-loop. (live demo). |
![]() |
import { createRoot } from 'react-dom/client'
import React, { useRef, useState } from 'react'
import { Canvas, useFrame } from '@react-three/fiber'
function Box(props) {
// This reference gives us direct access to the THREE.Mesh object
const ref = useRef()
// Hold state for hovered and clicked events
const [hovered, hover] = useState(false)
const [clicked, click] = useState(false)
// Subscribe this component to the render-loop, rotate the mesh every frame
useFrame((state, delta) => (ref.current.rotation.x += delta))
// Return the view, these are regular Threejs elements expressed in JSX
return (
<mesh
{...props}
ref={ref}
scale={clicked ? 1.5 : 1}
onClick={(event) => click(!clicked)}
onPointerOver={(event) => hover(true)}
onPointerOut={(event) => hover(false)}>
<boxGeometry args={[1, 1, 1]} />
<meshStandardMaterial color={hovered ? 'hotpink' : 'orange'} />
</mesh>
)
}
createRoot(document.getElementById('root')).render(
<Canvas>
<ambientLight intensity={Math.PI / 2} />
<spotLight position={[10, 10, 10]} angle={0.15} penumbra={1} decay={0} intensity={Math.PI} />
<pointLight position={[-10, -10, -10]} decay={0} intensity={Math.PI} />
<Box position={[-1.2, 0, 0]} />
<Box position={[1.2, 0, 0]} />
</Canvas>,

You need to be versed in both React and Threejs before rushing into this. If you are unsure about React consult the official React docs, especially the section about hooks. As for Threejs, make sure you at least glance over the following links:
