Correct me if I am wrong( and I very well could be.) I think that a bezier
patch is a uniform rational surface in that the contol points all have the
same weight. In a NURBS surface the control points can have different
weights and one point may affect the shape of the curve more than others. Of
coarse, I am not the expert. I'll bet Warp would know.
