classPerspectiveFrustum extends Object with Frustum
The viewing frustum is defined by 6 planes.
Each plane is represented by a Cartesian4 object, where the x, y, and z components
define the unit vector normal to the plane, and the w component is the distance of the
plane from the origin/camera position.
