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 );
} );
