SphereOutlineGeometry

new Cesium.SphereOutlineGeometry(options)
engine/Source/Core/SphereOutlineGeometry.js 31

A description of the outline of a sphere.
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 10 optional The count of stacks for the sphere (1 greater than the number of parallel lines).
slicePartitions number 8 optional The count of slices for the sphere (Equal to the number of radial lines).
subdivisions number 200 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 sphere = new Cesium.SphereOutlineGeometry({
  radius : 100.0,
  stackPartitions : 6,
  slicePartitions: 5
});
const geometry = Cesium.SphereOutlineGeometry.createGeometry(sphere);

Members

static Cesium.SphereOutlineGeometry.packedLength : number
engine/Source/Core/SphereOutlineGeometry.js 49

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

Methods

static Cesium.SphereOutlineGeometry.createGeometry(sphereGeometry) → Geometry|undefined
engine/Source/Core/SphereOutlineGeometry.js 115

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

static Cesium.SphereOutlineGeometry.pack(value, array, startingIndex) → Array.<number>
engine/Source/Core/SphereOutlineGeometry.js 60

Stores the provided instance into the provided array.
Name Type Default Description
value SphereOutlineGeometry 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.SphereOutlineGeometry.unpack(array, startingIndex, result) → SphereOutlineGeometry
engine/Source/Core/SphereOutlineGeometry.js 89

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