				<div class="class-description"><p>A layers object assigns an 3D object to 1 or more of 32
layers numbered <code>0</code> to <code>31</code> - internally the layers are stored as a
bit mask], and by default all 3D objects are a member of layer <code>0</code>.</p>
<p>This can be used to control visibility - an object must share a layer with
a camera to be visible when that camera's view is
rendered.</p>
<p>All classes that inherit from <a href="Object3D.html">Object3D</a> have an <code>layers</code> property which
is an instance of this class.</p></div>
