EllipsoidOutlineGeometry

new Cesium.EllipsoidOutlineGeometry(options)

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

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

Methods

staticCesium.EllipsoidOutlineGeometry.createGeometry(ellipsoidGeometry) → Geometry|undefined

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) → Array.<Number>

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.
Returns:
The array that was packed into

staticCesium.EllipsoidOutlineGeometry.unpack(array, startingIndex, result) → EllipsoidOutlineGeometry

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.
