Compensated evaluation of tensor product surfaces in CAGD
Delgado Gracia, J. (Universidad de Zaragoza)
Resumen: In computer-aided geometric design, a polynomial surface is usually represented in Bézier form. The usual form of evaluating such a surface is by using an extension of the de Casteljau algorithm. Using error-free transformations, a compensated version of this algorithm is presented, which improves the usual algorithm in terms of accuracy. A forward error analysis illustrating this fact is developed.
