uikit

Build performant 3D user interfaces for
threejs using R3F and yoga.

Perfect for games, XR (VR/AR), and any web-based Spatial Computing App.

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

What does it look like?

A simple UI with 2 containers horizontally aligned, rendered in fullscreen. When the user hovers over a container, the container's opacity changes.

import { createRoot } from 'react-dom/client'
import React from 'react'
import { Canvas } from '@react-three/fiber'
import { Fullscreen, Container } from '@react-three/uikit'

createRoot(document.getElementById('root')).render(
  <Canvas>
    <Fullscreen flexDirection="row" padding={10} gap={10}>
      <Container flexGrow={1} backgroundOpacity={0.5} hover={{ backgroundOpacity: 1 }} backgroundColor="red" />
      <Container flexGrow={1} backgroundOpacity={0.5} hover={{ backgroundOpacity: 1 }} backgroundColor="blue" />
    </Fullscreen>
  </Canvas>,
)
