		<h1>[name]</h1>

		<p class="desc">
			A [page:Layers] object assigns an [page:Object3D] to 1 or more of 32 layers numbered `0` to `31`
			- internally the layers are stored as a [link:https://en.wikipedia.org/wiki/Mask_(computing) bit mask], and by default all
			Object3Ds are a member of layer 0.<br /><br />

			This can be used to control visibility - an object must share a layer with a [page:Camera camera] to be visible when that camera's
			view is rendered.<br /><br />

			All classes that inherit from [page:Object3D] have an [page:Object3D.layers] property which is an instance of this class.
		</p>

		<h2>Examples</h2>

		<p>
			[example:webgl_layers WebGL / layers]
		</p>

		<h2>Constructor</h2>


		<h3>[name]()</h3>
		<p>
			Create a new Layers object, with membership initially set to layer 0.
		</p>

		<h2>Properties</h2>

		<h3>[property:Integer mask]</h3>
		<p>
			A bit mask storing which of the 32 layers this layers object is currently a member of.
		</p>


		<h2>Methods</h2>

		<h3>[method:undefined disable]( [param:Integer layer] )</h3>
		<p>
			layer - an integer from 0 to 31.<br /><br />

			Remove membership of this `layer`.
		</p>

		<h3>[method:undefined enable]( [param:Integer layer] )</h3>
		<p>
			layer - an integer from 0 to 31.<br /><br />

			Add membership of this `layer`.
		</p>

		<h3>[method:undefined set]( [param:Integer layer] )</h3>
		<p>
			layer - an integer from 0 to 31.<br /><br />

			Set membership to `layer`, and remove membership all other layers.
		</p>

		<h3>[method:Boolean test]( [param:Layers layers] )</h3>
		<p>
			layers - a Layers object<br /><br />

			Returns true if this and the passed `layers` object have at least one layer in common.
		</p>

		<h3>[method:Boolean isEnabled]( [param:Integer layer] )</h3>
		<p>
			layer - an integer from 0 to 31.<br /><br />

			Returns true if the given layer is enabled.
		</p>

		<h3>[method:undefined toggle]( [param:Integer layer] )</h3>
		<p>
			layer - an integer from 0 to 31.<br /><br />

			Toggle membership of `layer`.
		</p>

		<h3>[method:undefined enableAll]()</h3>
		<p>
			Add membership to all layers.
		</p>

		<h3>[method:undefined disableAll]()</h3>
		<p>
			Remove membership from all layers.
		</p>
