RingGeometry

A class for generating a two-dimensional ring geometry.

Code Example​

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

Constructor​

RingGeometry​

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

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.

Properties​

See the base BufferGeometry class for common properties.

parameters​

parameters: Object;

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

Methods​
