<div>{{APIRef("WebVR API")}}{{SeeCompatTable}}</div>
<p>The <code><strong>requestAnimationFrame()</strong></code> method of the {{domxref("VRDisplay")}} interface is a special implementation of {{domxref("Window.requestAnimationFrame")}} containing a callback function that will be called every time a new frame of the <code>VRDisplay</code> presentation is rendered:</p>
<ul>
<li>When the <code>VRDisplay</code> is not presenting a scene, this is functionally equivalent to {{domxref("Window.requestAnimationFrame")}}.</li>
<li>When the VRDisplay is presenting, the callback is called at the native refresh rate of the <code>VRDisplay</code>.</li>
</ul>
<h2 id="Syntax">Syntax</h2>
<pre class="brush: js">var handle = vrDisplayInstance.requestAnimationFrame(<em>callback</em>);

<h3 id="Parameters">Parameters</h3>

<dd>A callback function that will be called every time a new frame of the <code>VRDisplay</code> presentation is rendered.</dd>
</dl>
<h3 id="Return_value">Return value</h3>
<p>A long representing the handle of the <code>requestAnimationFrame()</code> call. This can then be passed to a {{domxref("VRDisplay.cancelAnimationFrame()")}} call to unregister the callback.</p>
