- <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>
- <iframe src='scenes/geometry-browser.html#CircleGeometry'></iframe>
- <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]([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.
