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 );


[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 8.
phiSegments — Minimum is 1. Default is 1.
thetaStart — Starting angle. Default is 0.
thetaLength — Central angle. Default is Math.PI * 2.


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.
