SphereGeometry
A class for generating sphere geometries.
Code Example
const geometry = new THREE.SphereGeometry( 15, 32, 16 ); const material = new
THREE.MeshBasicMaterial( { color: 0xffff00 } ); const sphere = new THREE.Mesh(
geometry, material ); scene.add( sphere );
Constructor
SphereGeometry
function SphereGeometry( radius: Float, widthSegments: Integer,
heightSegments: Integer, phiStart: Float, phiLength: Float, thetaStart: Float,
thetaLength: Float ): void;
radius — sphere radius. Default is 1.
widthSegments — number of horizontal segments. Minimum value is 3, and the
default is 32.
heightSegments — number of vertical segments. Minimum value is 2, and the
default is 16.
phiStart — specify horizontal starting angle. Default is 0.
phiLength — specify horizontal sweep angle size. Default is Math.PI * 2.
thetaStart — specify vertical starting angle. Default is 0.
thetaLength — specify vertical sweep angle size. Default is Math.PI.
The geometry is created by sweeping and calculating vertexes around the Y axis
(horizontal sweep) and the Z axis (vertical sweep). Thus, incomplete spheres
(akin to 'sphere slices') can be created through the use of different values
of phiStart, phiLength, thetaStart and thetaLength, in order to define the
points in which we start (or end) calculating those vertices.

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