<h1>[name]</h1>
<div 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.
</div>
<h2>Example</h2>
<code>var material = new THREE.MeshBasicMaterial({
color: 0x0000ff
});
var radius = 5;
var segments = 32;
var circleGeometry = new THREE.CircleGeometry( radius, segments );
var circle = new THREE.Mesh( circleGeometry, material );
scene.add( circle );
</code>
<h2>Constructor</h2>
<h3>[name]([page:Float radius], [page:Integer segments], [page:Float thetaStart], [page:Float thetaLength])</h3>
<div>
radius — Radius of the circle, default = 50.<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.
