EllipsoidOutlineGeometry

new EllipsoidOutlineGeometry(optionsopt)

A description of the outline of an ellipsoid centered at the origin.
Parameters:
Name Type Attributes Description
options Object <optional>
 Object with the following properties:
Properties
Name Type Attributes Default Description
radii Cartesian3 <optional>
 Cartesian3(1.0, 1.0, 1.0) The radii of the ellipsoid in the x, y, and z directions.
stackPartitions Number <optional>
 10 The count of stacks for the ellipsoid (1 greater than the number of parallel lines).
slicePartitions Number <optional>
 8 The count of slices for the ellipsoid (Equal to the number of radial lines).
subdivisions Number <optional>
 128 The number of points per line, determining the granularity of the curvature.

Methods

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

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

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

Parameters:
Name Type Attributes Default Description
value EllipsoidOutlineGeometry 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) → {EllipsoidOutlineGeometry}

Retrieves an instance from a packed array.
Parameters:
Name Type Attributes Default Description
