# SphereGeometry

#### new Cesium.SphereGeometry(options)
Core/SphereGeometry.js 44

  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);

### Members

#### staticCesium.SphereGeometry.packedLength : Number
Core/SphereGeometry.js 62

  The number of elements used to pack the object into an array.

### Methods

#### staticCesium.SphereGeometry.createGeometry(sphereGeometry) → Geometry
Core/SphereGeometry.js 120

  Computes the geometric representation of a sphere, including its vertices, indices, and a bounding sphere.

  Name | Type | Description
  --- | --- | ---
  `sphereGeometry` | SphereGeometry | A description of the sphere.

  ##### Returns:

  The computed vertices and indices.

#### staticCesium.SphereGeometry.pack(value, array, startingIndex)
Core/SphereGeometry.js 71

  Stores the provided instance into the provided array.

  Name | Type | Default | Description
  --- | --- | --- | ---
  `value` | SphereGeometry |  | The value to pack.
  `array` | Array.<Number> |  | The array to pack into.
  `startingIndex` | Number | `0` | optional The index into the array at which to start packing the elements.

#### staticCesium.SphereGeometry.unpack(array, startingIndex, result) → SphereGeometry
Core/SphereGeometry.js 98

  Retrieves an instance from a packed array.

  Name | Type | Default | Description
  --- | --- | --- | ---
  `array` | Array.<Number> |  | The packed array.
  `startingIndex` | Number | `0` | optional The starting index of the element to be unpacked.
  `result` | SphereGeometry |  | optional The object into which to store the result.

  ##### Returns:

  The modified result parameter or a new SphereGeometry instance if one was not provided.
