Computing values and derivatives of Bézier and B-spline tensor products

Abstract We give an efficient algorithm for evaluating Bezier and B-spline tensor products for both positions and normals. The algorithm is an extension of a method for computing the position and tangent to a Bezier curve, and is asymptotically twice as fast as the standard bilinear algorithm.
