Object

Object with the following properties:

Name	Type	Default	Description
`frustum`	PerspectiveFrustum \| OrthographicFrustum		The frustum.
`origin`	Cartesian3		The origin of the frustum.
`orientation`	Quaternion		The orientation of the frustum.
`vertexFormat`	VertexFormat	`VertexFormat.DEFAULT`	optional The vertex attributes to be computed.

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

staticCesium.FrustumGeometry.createGeometry(frustumGeometry) → Geometry|undefined Core/FrustumGeometry.js 338

Computes the geometric representation of a frustum, including its vertices, indices, and a bounding sphere.

Name	Type	Description
`frustumGeometry`	FrustumGeometry	A description of the frustum.

The computed vertices and indices.

staticCesium.FrustumGeometry.pack(value, array, startingIndex) → Array.<Number> Core/FrustumGeometry.js 106

Stores the provided instance into the provided array.

Name	Type	Default	Description
`value`	FrustumGeometry		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.

The array that was packed into

staticCesium.FrustumGeometry.unpack(array, startingIndex, result) Core/FrustumGeometry.js 151

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`	FrustumGeometry		optional The object into which to store the result.
