Description
A rectangular rational Bézier surface of degree p-by-q is described by
where and are the Bernstein basis functions of degree p and q, respectively, as described in the entry of BezierCurve. This surface description is called rectangular because the parameter domain is rectangular; that is, the two parameters s and t can vary freely in given intervals. The homogeneous control points Pw[j][i] used in the serialization of a rational surface have the components:
A polynomial surface has all weights equal to 1.
