This guide provides a brief overview of the basic components of a web-based VR application
|
|
|
made with three.js.

<h2>Workflow</h2>
|
|
|
|
|
|
<p>
|
|
|
First, you have to include [link:https://github.com/mrdoob/three.js/blob/master/examples/jsm/webxr/VRButton.js VRButton.js]
|
|
|
into your project.
|
|
|
</p>
|
|
|
|
|
|
<pre class="prettyprint notranslate lang-js" translate="no">
|
|
|
import { VRButton } from 'three/addons/webxr/VRButton.js';
|
|
|
</pre>
|
|
|
|
|
|
<p>
|
|
|
*VRButton.createButton()* does two important things: It creates a button which indicates
|
|
|
VR compatibility. Besides, it initiates a VR session if the user activates the button. The only thing you have
|
|
|
to do is to add the following line of code to your app.
|
|
|
</p>
|
|
|
|
|
|
<pre class="prettyprint notranslate lang-js" translate="no">
|
|
|
document.body.appendChild( VRButton.createButton( renderer ) );
|
|
|
</pre>
|
|
|
|
|
|
<p>
|
|
|
Next, you have to tell your instance of `WebGLRenderer` to enable XR rendering.
|
|
|
</p>
|
|
|
|
|
|
<pre class="prettyprint notranslate lang-js" translate="no">
|
|
|
renderer.xr.enabled = true;
|
|
|
</pre>
|
|
|
|
|
|
<p>
|
|
|
Finally, you have to adjust your animation loop since we can't use our well known
|
|
|
*window.requestAnimationFrame()* function. For VR projects we use `renderer.setAnimationLoop()`.
|
|
|
The minimal code looks like this:
|
|
|
</p>
|
|
|
|
|
|
<pre class="prettyprint notranslate lang-js" translate="no">
|
|
|
renderer.setAnimationLoop( function () {
|
|
|
|
|
|
renderer.render( scene, camera );
|
|
|
|
|
|
} );
|
|
|
</pre>
|
|
|
|
|
|
