				<div class="class-description"><p>This is a helper for visualising a given light's shadow map.
It works for shadow casting lights: DirectionalLight and SpotLight.
It renders out the shadow map and displays it on a HUD.</p>
<p>This module can only be used with <a href="WebGLRenderer.html">WebGLRenderer</a>. When using <a href="WebGPURenderer.html">WebGPURenderer</a>,
import the class from <code>ShadowMapViewerGPU.js</code>.</p></div>
