This is the 4th coefficient.

Think of the first 3 numbers as the surface normal of the plane and the
4th as the offset and you have a fairly intuitive description of the
plane equation. This only really works for unit length normals,
otherwise you have to rescale by the normal length.

Cheers,Angus.
