Detailed Description

Arbitrarily-oriented plane.

The point p0 is a point on the plane. Normal is the normal vector of the plane. If you have a plane in a,b,c,d form remember that n = [a,b,c] and you can compute a suitable point p0 as p0 = -n*d. The normal will get normalized, so it need not already be unit length.

Generate returns the point p0. Within returns true if the point is in the positive half-space of the plane (in the plane or on the side that Normal points to).
