Detailed Description
basic 2D plane in 3D space.
This is composed of a normal (vector), and a distance D (along the normal) from the origin.
Note that a point p in the plane satisfies the equation n.p = d.
Likewise, the distance from any point p to the plane is n.p - d (= 0 for points p in the plane, obviously).
