[name]

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.

Example

var geometry = new v3d.CircleGeometry(5, 32); var material = new v3d.MeshBasicMaterial({ color: 0xffff00 }); var circle = new v3d.Mesh(geometry, material); scene.add(circle);

Constructor

[name]([param:Float radius], [param:Integer segments], [param:Float thetaStart], [param:Float thetaLength])

radius — Radius of the circle, default = 1.
segments — Number of segments (triangles), minimum = 3, default = 8.
thetaStart — Start angle for first segment, default = 0 (three o'clock position).
thetaLength — The central angle, often called theta, of the circular sector. The default is 2*Pi, which makes for a complete circle.

Properties

[property:Object parameters]

An object with a property for each of the constructor parameters. Any modification after instantiation does not change the geometry.
