From PS-splines to NURPS

Abstract

A normalized B-spline representation for Powell-Sabin (PS) spline surfaces is extended to piecewise rational surfaces (NURPS). We investigate the adaptation of existing algorithms operating on B-splines to this more general case, the influence of weights and their geometrical interpretation, the possibility of representing planar sections, and the conversion from rational Bezier to NURPS surfaces.
