public class Frustum
extends Cone

This class represents the geometry of a frustum. It inherits all properties from the superclass Cone. However, the geometry is modified such that the part from the cone's tip up to the plane at z=1 is removed. I.e., the frustum is the intersection of the cone and the half-space above the plane z=1.
