		<h1>[name]</h1>

		<p class="desc">
			Creates a visual aid consisting of a spherical [page:Mesh] for a
			[page:HemisphereLight HemisphereLight].
		</p>

		<h2>Code Example</h2>

		<code>
		const light = new THREE.HemisphereLight( 0xffffbb, 0x080820, 1 );
		const helper = new THREE.HemisphereLightHelper( light, 5 );
		scene.add( helper );
		</code>

		<h2>Constructor</h2>

		<h3>
			[name]( [param:HemisphereLight light], [param:Number sphereSize],
			[param:Hex color] )
		</h3>
		<p>
			[page:HemisphereLight light] -- The light being visualized. <br /><br />

			[page:Number size] -- The size of the mesh used to visualize the light.<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:Object3D] class for common properties.</p>

		<h3>[property:HemisphereLight light]</h3>
		<p>Reference to the HemisphereLight being visualized.</p>

		<h3>[property:Object matrix]</h3>
		<p>
			Reference to the hemisphereLight'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 hemisphereLight'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:Object3D] class for common methods.</p>

		<h3>[method:undefined dispose]()</h3>
		<p>
			Frees the GPU-related resources allocated by this instance. Call this
			method whenever this instance is no longer used in your app.
		</p>

		<h3>[method:undefined update]()</h3>
		<p>
			Updates the helper to match the position and direction of the
			[page:.light].
		</p>
