		<h1>Draw Mode Constants</h1>
		<p>
			These are valid values for Mesh.drawMode, and control how the list of vertices is interpeted once sent to the GPU.</p>
		</p>
		<h2>Draw Modes</h2>
		<code>
			THREE.TrianglesDrawMode<br />
		</code>
		<p>
			This is the default, and results in every three consecutive vertices (v0, v1, v2), (v2, v3, v5), ... being interpreted as a separate triangle. <br />
			If the number of vertices is not a multiple of 3, excess vertices are ignored.
		</p>
		<code>
			THREE.TriangleStripDrawMode<br />
		</code>
		<p>
			This will result in a series of triangles connected in a strip, given by (v0, v1, v2), (v2, v1, v3), (v2, v3, v4), ... so that every subsequent triangle shares two vertices with the previous triangle.
		</p>
		<code>
			THREE.TriangleFanDrawMode
		</code>
		<p>
			This will result in a series of triangles each sharing the first vertex (like a fan), given by (v0, v1, v2), (v0, v2, v3), (v0, v3, v4), ...
		</p>


		<h2>Usage</h2>

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

		geometry.vertices.push(
			new THREE.Vector3( -10,  10, 0 ),
			new THREE.Vector3( -10, -10, 0 ),
			new THREE.Vector3(  10, -10, 0 ),
			...
		);
		geometry.faces.push( new THREE.Face3( 0, 1, 2 ), ... );

		var material = new THREE.MeshBasicMaterial( { color: 0xffff00 } );

		var mesh = new THREE.Mesh( geometry, material );
		mesh.drawMode = THREE.TrianglesDrawMode; //default

		scene.add( mesh );
		</code>
