# SphereGeometry

#### new SphereGeometry(options)

  A description of a sphere centered at the origin.

  Name | Type | Description
  --- | --- | ---

  `options`

  Object

  optional Object with the following properties:

  Name | Type | Default | Description
  --- | --- | --- | ---
  `radius` | Number | `1.0` | optional The radius of the sphere.
  `stackPartitions` | Number | `64` | optional The number of times to partition the ellipsoid into stacks.
  `slicePartitions` | Number | `64` | optional The number of times to partition the ellipsoid into radial slices.
  `vertexFormat` | VertexFormat | `VertexFormat.DEFAULT` | optional The vertex attributes to be computed.

  ##### Throws:

  - DeveloperError : options.slicePartitions cannot be less than three.
  - DeveloperError : options.stackPartitions cannot be less than three.

  ##### Example:

      var sphere = new Cesium.SphereGeometry({
        radius : 100.0,
        vertexFormat : Cesium.VertexFormat.POSITION_ONLY
      });
      var geometry = Cesium.SphereGeometry.createGeometry(sphere);
