Methods

(static) createGeometry(ellipsoidGeometry) → {Geometry|undefined}

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

(static) pack(value, array, startingIndexopt) → {Array.<Number>}

Stores the provided instance into the provided array.
Parameters:
Name Type Attributes Default Description
value EllipsoidGeometry The value to pack.
array Array.<Number> The array to pack into.
startingIndex Number <optional>
 0 The index into the array at which to start packing the elements.
Source:
Returns:
The array that was packed into
Type
Array.<Number>

(static) unpack(array, startingIndexopt, resultopt) → {EllipsoidGeometry}

Retrieves an instance from a packed array.
Parameters:
Name Type Attributes Default Description
array Array.<Number> The packed array.
startingIndex Number <optional>
 0 The starting index of the element to be unpacked.
result EllipsoidGeometry <optional>
 The object into which to store the result.
Source:
Returns:
The modified result parameter or a new EllipsoidGeometry instance if one was not provided.
