		<div class="desc">Level of Detail - Show meshes with more or less geometry based on distance.</div>

		<h2>Example</h2>

		<div>
		[example:webgl_lod LOD]
		</div>

		<code>
		var lod = new THREE.LOD();

		//Create 5 levels of spheres
		for( var i = 0; i < 5; i++ ) {

			var geometry = new THREE.IcosahedronGeometry( 10, 5 - i )

			new THREE.Mesh( geometry, material );

			lod.addLevel( mesh, i * 50 );

		}
		</code>

		<h2>Constructor</h2>


		<h3>[name]()</h3>


		<h2>Properties</h2>
		<div>See the base [page:Object3D] class for common properties.</div>


		<h3>[property:array levels]</h3>
		<div>
		An array of [page:object level] objects
		</div>
		<div>
		level is an object with two properties.
		</div>
		<div>
		distance -- The distance at which to display this level of detail<br />
		object -- The Object3D which will be displayed
		</div>

		<h2>Methods</h2>
		<div>See the base [page:Object3D] class for common methods.</div>


		<h3>[method:null addLevel]( [page:Object3D mesh], [page:Float distance] )</h3>
		<div>
		mesh -- The Object3D to display <br />
		distance -- The distance at which to display this level of detail
		</div>
		<div>
		Adds a mesh that will display at a certain distance and greater. Typically the further away the distance,
		the lower the detail on the mesh.
		</div>

		<h3>[method:Object3D getObjectForDistance]( [page:Float distance] )</h3>
		<div>
		Get a reference to the first [page:Object3D] (mesh) that is greater than supplied distance.
		</div>

		<h3>[method:null update]( [page:Camera camera] )</h3>
		<div>
		camera -- The current camera
		</div>
		<div>
		Update the visiblility of the level of detail based on the distance from the camera.
		</div>

		<h3>[method:LOD clone]()</h3>
		<div>
		Returns a clone of this LOD object and its associated distance specific objects.
		</div>
