				<div class="class-description"><p>Progressive Light Map Accumulator, by <a href="https://github.com/zalo/">zalo</a>.</p>
<p>To use, simply construct a <code>ProgressiveLightMap</code> object,
<code>plmap.addObjectsToLightMap(object)</code> an array of semi-static
objects and lights to the class once, and then call
<code>plmap.update(camera)</code> every frame to begin accumulating
lighting samples.</p>
<p>This should begin accumulating lightmaps which apply to
your objects, so you can start jittering lighting to achieve
the texture-space effect you're looking for.</p>
<p>This class can only be used with <a href="WebGLRenderer.html">WebGLRenderer</a>.
When using <a href="WebGPURenderer.html">WebGPURenderer</a>, import from <code>ProgressiveLightMapGPU.js</code>.</p></div>
