<p class="desc">
This displays a helper object consisting of a spherical [page:Mesh] for visualizing
a [page:PointLight].
</p>
<h2>Example</h2>
[example:webgl_helpers WebGL / helpers]
<code>
var pointLight = new THREE.PointLight( 0xff0000, 1, 100 );
pointLight.position.set( 10, 10, 10 );
scene.add( pointLight );
var sphereSize = 1;
var pointLightHelper = new THREE.PointLightHelper( pointLight, sphereSize );
scene.add( pointLightHelper );
</code>
<h2>Constructor</h2>
<h3>[name]( [param:PointLight light], [param:Float sphereSize], [param:Hex color] )</h3>
<p>
[page:PointLight light] -- The light to be visualized. <br /><br />
[page:Float sphereSize] -- (optional) The size of the sphere helper. Default is *1*.<br /><br />
[page:Hex color] -- (optional) if this is not the set the helper will take the color of the light.
</p>
<h2>Properties</h2>
<p>See the base [page:Mesh] class for common properties.</p>
<h3>[property:PointLight light]</h3>
<p>The [page:PointLight] that is being visualized.</p>
<h3>[property:object matrix]</h3>
<p>Reference to the pointLight's [page:Object3D.matrixWorld matrixWorld].</p>
<h3>[property:object matrixAutoUpdate]</h3>
<p>
See [page:Object3D.matrixAutoUpdate]. Set to *false* here as the helper is using the
pointLight's [page:Object3D.matrixWorld matrixWorld].
</p>
<h3>[property:hex color]</h3>
<p>
The color parameter passed in the constructor. Default is *undefined*. If this is changed, the helper's color will update
the next time [page:.update update] is called.
</p>
<h2>Methods</h2>
<p>See the base [page:Mesh] class for common methods.</p>
<h3>[method:null dispose]()</h3>
<p>Dispose of the pointLightHelper.</p>
<h3>[method:null update]()</h3>
<p>Updates the helper to match the position of the [page:.light].</p>
