		<h1>[name]</h1>

		<p class="desc">CircleGeometry is a simple shape of Euclidean geometry.  It is contructed from a number of triangular segments that are oriented around a central point and extend as far out as a given radius.  It is built counter-clockwise from a start angle and a given central angle.  It can also be used to create regular polygons, where the number of segments determines the number of sides.

		<h2>Example</h2>

		<code>
		var geometry = new THREE.CircleGeometry( 5, 32 );
		var material = new THREE.MeshBasicMaterial( { color: 0xffff00 } );
		var circle = new THREE.Mesh( geometry, material );
		scene.add( circle );
		</code>

		<h2>Constructor</h2>

		<h3>[name]([param:Float radius], [param:Integer segments], [param:Float thetaStart], [param:Float thetaLength])</h3>
		<p>
		radius — Radius of the circle, default = 1.<br />
		segments — Number of segments (triangles), minimum = 3, default = 8.<br />
		thetaStart — Start angle for first segment, default = 0 (three o'clock position).<br />
		thetaLength — The central angle, often called theta, of the circular sector. The default is 2*Pi, which makes for a complete circle.
		</p>

		<h2>Properties</h2>

		<h3>[property:Object parameters]</h3>
		<p>
		An object with a property for each of the constructor parameters. Any modification after instantiation does not change the geometry.
		</p>
