		<h1>[name]</h1>

		<div class="desc">
		Use an array of [page:Bone bones] to create a skeleton that can be used by a
		[page:SkinnedMesh].
		</div>

		<h2>Example</h2>
		<div>

<code>
// Create a simple "arm"

var bones = [];

var shoulder = new THREE.Bone();
var elbow = new THREE.Bone();
var hand = new THREE.Bone();

shoulder.add( elbow );
elbow.add( hand );

bones.push( shoulder );
bones.push( elbow );
bones.push( hand );

shoulder.position.y = -5;
elbow.position.y = 0;
hand.position.y = 5;

var armSkeleton = new THREE.Skeleton( bones );
</code>
			See the [page:SkinnedMesh] page for an example of usage with standard [page:BufferGeometry].
 		</div>

		<h2>Constructor</h2>


		<h3>[name]( [page:Array bones], [page:Array boneInverses] )</h3>
		<div>
		[page:Array bones] - The array of [page:Bone bones]. Default is an empty array.<br/>
		[page:Array boneInverses] - (optional) An array of [page:Matrix4 Matrix4s].<br /><br />

		Creates a new [name].
		</div>


		<h2>Properties</h2>

		<h3>[property:Array bones]</h3>
		<div>
		The array of [page:bone bones]. Note this is a copy of the original array, not a reference,
		so you can modify the original array without effecting this one.
		</div>

		<h3>[property:Array boneInverses]</h3>
		<div>
		An array of [page:Matrix4 Matrix4s] that represent the inverse of the [page:Matrix4 matrixWorld]
		of the individual bones.
		</div>

		<h3>[property:Float32Array boneMatrices]</h3>
		<div>
		The array buffer holding the bone data when using a vertex texture.
		</div>

		<h3>[property:DataTexture boneTexture]</h3>
		<div>
		The [page:DataTexture] holding the bone data when using a vertex texture.
		</div>


		<h2>Methods</h2>

		<h3>[method:Skeleton clone]()</h3>
		<div>
		Returns a clone of this Skeleton object.
		</div>


		<h3>[method:null calculateInverses]()</h3>
		<div>Generates the [page:.boneInverses boneInverses] array if not provided in the constructor.</div>


		<h3>[method:null pose]()</h3>
		<div>Returns the skeleton to the base pose.</div>


		<h3>[method:null update]()</h3>
		<div>
		Updates the [page:Float32Array boneMatrices] and [page:DataTexture boneTexture] after changing the bones.
		This is called automatically by the [page:WebGLRenderer] if the skeleton is used with a [page:SkinnedMesh].
		</div>
