# [name]

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

### [name]([param:Float radius], [param:Integer widthSegments], [param:Integer heightSegments], [param:Float phiStart], [param:Float phiLength], [param:Float thetaStart], [param:Float thetaLength])

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.

## 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.
