Detailed Description

Actors are defined by a plane and a rectangle that limits that plane.

Planes are normally infinite, but Actors limit them to a rectangle. In 3D, this means a plane has 4 additional planes to limit them (north, west, south & east) To hold those 5 planes, we only need 5 "d" from Plane, and 5 normals (one for the main plane, 2 for north & south, 2 for west & east). However a Quaternion can represent all 5 normals: zAxis is normal, +/- yAxis is north & south, +/- xAxis is west & east.
