		<h1>[name]</h1>

		<div class="desc">Base class for geometries</div>


		<h2>Example</h2>

		<code>var geometry = new THREE.Geometry()

		geometry.vertices.push( new THREE.Vector3( -10,  10, 0 ) );
		geometry.vertices.push( new THREE.Vector3( -10, -10, 0 ) );
		geometry.vertices.push( new THREE.Vector3(  10, -10, 0 ) );

		geometry.faces.push( new THREE.Face3( 0, 1, 2 ) );

		geometry.computeBoundingSphere();
		</code>

		<h2>Constructor</h2>

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


		<h2>Properties</h2>

		<h3>.[page:Integer id]</h3>
		<div>
		Unique number of this geometry instance
		</div>
		
		<h3>.[page:String name]</h3>
		<div>
		Name for this geometry. Default is an empty string.
		</div>

		<h3>.[page:Array vertices]</h3>
		<div>
		Array of [page:Vector3 vertices].
		</div>

		<h3>.[page:Array colors]</h3>
		<div>
		Array of vertex [page:Color colors], matching number and order of vertices.<br />
		Used in [page:ParticleSystem], [page:Line] and [page:Ribbon].<br />
		[page:Mesh Meshes] use per-face-use-of-vertex colors embedded directly in faces.
		</div>

		<h3>.[page:Array materials]</h3>
		<div>
		Array of [page:Material materials].
		</div>

		<h3>.[page:Array faces]</h3>
		<div>
		Array of [page:Face3 triangles] or/and [page:Face4 quads].
		</div>

		<h3>.[page:Array faceUvs]</h3>
		<div>
		Array of face [page:UV] layers.<br />
		Each UV layer is an array of [page:UV] matching order and number of faces.
		</div>

		<h3>.[page:Array faceVertexUvs]</h3>
		<div>
		Array of face [page:UV] layers.<br />
		Each UV layer is an array of [page:UV] matching order and number of vertices in faces.
		</div>

		<h3>.[page:Array morphTargets]</h3>
		<div>
		Array of morph targets. Each morph target is a Javascript object:
		<code>{ name: "targetName", vertices: [ new THREE.Vertex(), ... ] }</code>
		Morph vertices match number and order of primary vertices.
		</div>

		<h3>.[page:Array morphColors]</h3>
		<div>
		Array of morph colors. Morph colors have similar structure as morph targets, each color set is a Javascript object:
		<code>morphColor = { name: "colorName", colors: [ new THREE.Color(), ... ] }</code>
		Morph colors can match either number and order of faces (face colors) or number of vertices (vertex colors).
		</div>

		<h3>.[page:Array skinWeights]</h3>
		<div>
		Array of skinning weights, matching number and order of vertices.
		</div>

		<h3>.[page:Array skinIndices]</h3>
		<div>
		Array of skinning indices, matching number and order of vertices.
		</div>

		<h3>.[page:Object boundingBox]</h3>
		<div>
		Bounding box.
		<code>{ min: new THREE.Vector3(), max: new THREE.Vector3() }</code>
		</div>

		<h3>.[page:Object boundingSphere]</h3>
		<div>
		Bounding sphere.
		<code>{ radius: float }</code>
		</div>

		<h3>.[page:Boolean hasTangents]</h3>
		<div>
		True if geometry has tangents. Set in [page:Geometry Geometry.computeTangents].
		</div>

		<h3>.[page:Boolean dynamic]</h3>
		<div>
		Set to *true* if attribute buffers will need to change in runtime (using "dirty" flags).<br/>
		Unless set to true internal typed arrays corresponding to buffers will be deleted once sent to GPU.
		</div>


		<h2>Methods</h2>

		<h3>.applyMatrix( [page:Matrix4 matrix] )</h3>
		<div>
		Bakes matrix transform directly into vertex coordinates.
		</div>

		<h3>.computeCentroids()</h3>
		<div>
		Computes centroids for all faces.
		</div>

		<h3>.computeFaceNormals()</h3>
		<div>
		Computes face normals.
		</div>

		<h3>.computeVertexNormals()</h3>
		<div>
		Computes vertex normals by averaging face normals.<br />
		Face normals must be existing / computed beforehand.
		</div>

		<h3>.computeTangents()</h3>
		<div>
		Computes vertex tangents.<br />
		Based on [link:http://www.terathon.com/code/tangent.html]<br />
		Geometry must have vertex [page:UV UVs] (layer 0 will be used).
		</div>

		<h3>.computeBoundingBox()</h3>
		<div>
		Computes bounding box of the geometry, updating [page:Geometry Geometry.boundingBox] attribute.
		</div>

		<h3>.computeBoundingSphere()</h3>
		<div>
		Computes bounding sphere of the geometry, updating [page:Geometry Geometry.boundingSphere] attribute.
		</div>
		
		<div>Neither bounding boxes or bounding spheres are computed by default. They need to be explicitly computed, otherwise they are *null*.</div>

		<h3>.mergeVertices()</h3>
		<div>
		Checks for duplicate vertices using hashmap.<br />
		Duplicated vertices are removed and faces' vertices are updated.
		</div>
