A class for generating a two-dimensional ring geometry.

Code Example

const geometry = new v3d.RingGeometry(1, 5, 32); const material = new v3d.MeshBasicMaterial({ color: 0xffff00, side: v3d.DoubleSide }); const mesh = new v3d.Mesh(geometry, material); scene.add(mesh);


RingGeometry(innerRadius : Float, outerRadius : Float, thetaSegments : Integer, phiSegments : Integer, thetaStart : Float, thetaLength : Float)

innerRadius — Default is 0.5.
outerRadius — Default is 1.
thetaSegments — Number of segments. A higher number means the ring will be more round. Minimum is 3. Default is 32.
phiSegments — Minimum is 1. Default is 1.
thetaStart — Starting angle. Default is 0.
thetaLength — Central angle. Default is Math.PI * 2.


See the base BufferGeometry class for common properties.

.parameters : Object

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