SphereGeometry

new Freedo.SphereGeometry(options)
Core/SphereGeometry.js 32

A description of a sphere centered at the origin.
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 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 sphere = new Freedo.SphereGeometry({
  radius : 100.0,
  vertexFormat : Freedo.VertexFormat.POSITION_ONLY
});
const geometry = Freedo.SphereGeometry.createGeometry(sphere);

Members

static Freedo.SphereGeometry.packedLength : Number
Core/SphereGeometry.js 50

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

Methods

static Freedo.SphereGeometry.createGeometry(sphereGeometry) → Geometry|undefined
Core/SphereGeometry.js 115

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

static Freedo.SphereGeometry.pack(value, array, startingIndex) → Array.<Number>
Core/SphereGeometry.js 61

Stores the provided instance into the provided array.
Name Type Default Description
value SphereGeometry 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 Freedo.SphereGeometry.unpack(array, startingIndex, result) → SphereGeometry
Core/SphereGeometry.js 86

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