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

new RingGeometry( innerRadius : number, outerRadius : number, thetaSegments : number, phiSegments : number, thetaStart : number, thetaLength : number )

Constructs a new ring geometry.

innerRadius

The inner radius of the ring.

Default is 0.5.
outerRadius

The outer radius of the ring.

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 in radians.

Default is 0.
thetaLength

Central angle in radians.

Default is Math.PI*2.

Properties

.parameters : Object

Holds the constructor parameters that have been used to generate the geometry. Any modification after instantiation does not change the geometry.

Static Methods

.fromJSON( data : Object ) : RingGeometry

Factory method for creating an instance of this class from the given JSON object.

data

A JSON object representing the serialized geometry.
Returns: A new instance.
