[name]

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

[name]([param:Float innerRadius], [param:Float outerRadius], [param:Integer thetaSegments], [param:Integer phiSegments], [param:Float thetaStart], [param:Float thetaLength])

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 — Number of segments per ring segment. Minimum is `1`. Default is `1`.
thetaStart — Starting angle. Default is `0`.
thetaLength — Central angle. Default is Math.PI * 2.

Properties

See the base [page:BufferGeometry] class for common properties.

[property:Object parameters]

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

Methods

See the base [page:BufferGeometry] class for common methods.
