<divclass="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 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 );
