ThreeJS Creating VR Content

This article gives a quick introduction of the main components of a three.js-based web-based VR application.

Workflow     

First, you have to include VRButton.js into your project.

import { VRButton } from 'three/examples/jsm/webxr/VRButton.js';

VRButton. createButton() performs two critical tasks: It creates a button that tells whether or not the game is compatible with virtual reality. It also starts a VR experience when the user presses the button. All you have to do is copy and paste the following code into your app.

document.body.appendChild( VRButton.createButton( renderer ) );

Next, you have to tell your instance of WebGLRenderer to enable XR rendering.

renderer.xr.enabled = true;

Finally, you have to adjust your animation loop since we can't use our well known window.requestAnimationFrame() function. For VR projects we use setAnimationLoop. The minimal code looks like this:

renderer.setAnimationLoop( function () {


	renderer.render( scene, camera );


} );
