WebXR + react-three-fiber

React components and hooks for creating VR/AR applications with react-three-fiber

Note: Extremely early in development. Contributors welcome!

These demos are real, you can click them! They contain the full code, too.

npm install react-xr

Add VRCanvas or ARCanvas component (or replace your existing react-three-fiber Canvas component)

import { VRCanvas } from 'react-xr'
function App() {
 return <VRCanvas>{/* All the stuff goes here */}</VRCanvas>
}

To get started with default controller models add DefaultXRControllers component. It will fetch appropriate input profile models. You can learn more here.

import { VRCanvas, DefaultXRControllers } from 'react-xr'
function App() {
 return (
 <VRCanvas>
 <DefaultXRControllers />
 </VRCanvas>
 )
}

You can access controllers' state (position, orientation, etc.) by using useXR() hook

const { controllers } = useXR()

Extended react-three-fiber Canvas that includes:

• Button to start VR session
• Color management
• VR Mode
• react-xr context

For VR apps use VRCanvas and for AR apps use ARCanvas

import { VRCanvas } from 'react-xr'
function App() {
 return <VRCanvas>{/* All the stuff goes here */}</VRCanvas>
}

Hook that can only beused by components insde component.

const { controllers } = useXR()

Controllers is an array of XRController objects

interface XRController {
 grip: Group
 controller: Group
 inputSource?: XRInputSource
 // ...
 // more in XRController.ts
}

grip and controller are ThreeJS groups that have the position and orientation of xr controllers. grip has an orientation that should be used to render virtual objects such that they appear to be held in the user’s hand and controller has an orientation of the preferred pointing ray.

inputSource is the WebXR input source (MDN). Note that it will not be available before controller is connected.

Every controller emits following events: select, selectstart, selectend, squeeze, squeezestart, squeezeend.

To listen to those events use useXREvent hook:

const onSqueeze = useCallback(() => console.log('Squeezed'), [])
useXREvent('squeeze', onSqueeze)

it supports optional third parameter with options

const onSqueeze = useCallback(() => console.log('Left controller squeeze'), [])
useXREvent('squeeze', onSqueeze, { handedness: 'left' })

react-xr comes with built-in high level interaction components.

Hover component will allow you for detecting when ray shot from the controllers is pointing at the given mesh.

<Hover onChange={(value) => console.log(value ? 'hovered' : 'blurred')}>{/* your mesh here */}</Hover>

Select can be used when you need to select some mesh. Component will trigger onSelect function when controller is pointing at the given mesh and select event was fired.

<Select onSelect={() => console.log('selected')}>{/* your mesh here */}</Select>
