Parametrized polynomial spline curves are defined by an S-polygon, but locally they are Bdzier curves defined by a B-polygon. Two algorithms are given which construct one polygon from the other and vice versa. The generalization to surfaces is straightforward. This may be of some interest in CA D be

Sections of parametric surfaces defined by equally spaced parameter values can be very unevenly spaced physically. This can cause practical problems when the surface is to be drawn or machined automatically. This paper describes a method for imposing a good parametrization on a curve constructed by

Conversion methods are required for the exchange of data. First a given rational B-spline surface with curved boundaries will be segmented by curvature oriented arguments, then these patches will be converted into bicubic or biquintic integral B4zier patches with help of geometric continuity conditi
