==The Plane==
In POV a plane is considered to have a volume, any point that is "under" the plane is inside, and any point that is "above" the plane is outside. This becomes important when you use a plane in CSG. A plane is defined in POV by a direction vector, and a float distance. The direction vector indicates the "up" direction, and the distance is how far in that direction from the origin the surface begins.

+In POV, a plane is one of the five Infinite Solid Primitives.  It is a flat surface that extends infinitely in all directions (unless clipped by an object).  Planes are considered to have a volume, any point that is "under" the plane is inside, and any point that is "above" the plane is outside. This becomes important when you use a plane in CSG. A plane is defined in POV by a normal vector, and a float distance. The normal vector indicates the surface normal of the plane, and the distance is how far in that direction from the origin the surface begins.
