EllipsoidOutlineGeometry

new Cesium.EllipsoidOutlineGeometry(options)
engine/Source/Core/EllipsoidOutlineGeometry.js 49

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

Members

static Cesium.EllipsoidOutlineGeometry.packedLength : Number
engine/Source/Core/EllipsoidOutlineGeometry.js 101

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

Methods

static Cesium.EllipsoidOutlineGeometry.createGeometry(ellipsoidGeometry) → Geometry|undefined
engine/Source/Core/EllipsoidOutlineGeometry.js 223

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.

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

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

static Cesium.EllipsoidOutlineGeometry.unpack(array, startingIndex, result) → EllipsoidOutlineGeometry
engine/Source/Core/EllipsoidOutlineGeometry.js 165

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.
