# EllipsoidOutlineGeometry

#### new Cesium.EllipsoidOutlineGeometry(options)
Core/EllipsoidOutlineGeometry.js 62

  A description of the outline of an ellipsoid centered at the origin.

  Name | Type | Description
  --- | --- | ---
  `options` | Object | optional Object with the following properties:
  Name | Type | Default | Description
  --- | --- | --- | ---
  `radii` | Cartesian3 | `Cartesian3(1.0, 1.0, 1.0)` | optional The radii of the ellipsoid in the x, y, and z directions.
  `stackPartitions` | Number | `10` | optional The count of stacks for the ellipsoid (1 greater than the number of parallel lines).
  `slicePartitions` | Number | `8` | optional The count of slices for the ellipsoid (Equal to the number of radial lines).
  `subdivisions` | Number | `128` | optional The number of points per line, determining the granularity of the curvature .

  ##### Throws:

  - DeveloperError : options.stackPartitions must be greater than or equal to one.
  - DeveloperError : options.slicePartitions must be greater than or equal to zero.
  - DeveloperError : options.subdivisions must be greater than or equal to zero.

  ##### Example:

      var ellipsoid = new Cesium.EllipsoidOutlineGeometry({
        radii : new Cesium.Cartesian3(1000000.0, 500000.0, 500000.0),
        stackPartitions: 6,
        slicePartitions: 5
      });
      var geometry = Cesium.EllipsoidOutlineGeometry.createGeometry(ellipsoid);

### Members

#### staticCesium.EllipsoidOutlineGeometry.packedLength : Number
Core/EllipsoidOutlineGeometry.js 93

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

### Methods

#### staticCesium.EllipsoidOutlineGeometry.createGeometry(ellipsoidGeometry) → Geometry
Core/EllipsoidOutlineGeometry.js 175

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

  Name | Type | Description
  --- | --- | ---
  `ellipsoidGeometry` | EllipsoidOutlineGeometry | A description of the ellipsoid outline.

  ##### Returns:

  The computed vertices and indices.

#### staticCesium.EllipsoidOutlineGeometry.pack(value, array, startingIndex)
Core/EllipsoidOutlineGeometry.js 102

  Stores the provided instance into the provided array.

  Name | Type | Default | Description
  --- | --- | --- | ---
  `value` | EllipsoidOutlineGeometry |  | 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.EllipsoidOutlineGeometry.unpack(array, startingIndex, result) → EllipsoidOutlineGeometry
Core/EllipsoidOutlineGeometry.js 138

  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` | EllipsoidOutlineGeometry |  | optional The object into which to store the result.

  ##### Returns:

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