A description 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.
innerRadii Cartesian3 options.radii optional The inner radii of the ellipsoid in the x, y, and z directions.
minimumClock number 0.0 optional The minimum angle lying in the xy-plane measured from the positive x-axis and toward the positive y-axis.
maximumClock number 2*PI optional The maximum angle lying in the xy-plane measured from the positive x-axis and toward the positive y-axis.
minimumCone number 0.0 optional The minimum angle measured from the positive z-axis and toward the negative z-axis.
maximumCone number PI optional The maximum angle measured from the positive z-axis and toward the negative z-axis.
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:
Example:
const ellipsoid = new Cesium.EllipsoidGeometry({
  vertexFormat : Cesium.VertexFormat.POSITION_ONLY,
  radii : new Cesium.Cartesian3(1000000.0, 500000.0, 500000.0)
});
const geometry = Cesium.EllipsoidGeometry.createGeometry(ellipsoid);

Members

static Cesium.EllipsoidGeometry.packedLength : number
engine/Source/Core/EllipsoidGeometry.js 100

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

Methods

static Cesium.EllipsoidGeometry.createGeometry(ellipsoidGeometry) → Geometry|undefined
engine/Source/Core/EllipsoidGeometry.js 231

Computes the geometric representation of an ellipsoid, including its vertices, indices, and a bounding sphere.
Name Type Description
ellipsoidGeometry EllipsoidGeometry A description of the ellipsoid.
Returns:
The computed vertices and indices.

static Cesium.EllipsoidGeometry.pack(value, array, startingIndex) → Array.<number>
engine/Source/Core/EllipsoidGeometry.js 112

Stores the provided instance into the provided array.
Name Type Default Description
value EllipsoidGeometry 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

static Cesium.EllipsoidGeometry.unpack(array, startingIndex, result) → EllipsoidGeometry
engine/Source/Core/EllipsoidGeometry.js 168

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 EllipsoidGeometry optional The object into which to store the result.
Returns:
The modified result parameter or a new EllipsoidGeometry instance if one was not provided.
