✦ Synopsis

The aim of this paper is to describe applications of variable degree polynomials in the area of curve and surface construction. These polynomials have the same simple structure and the same properties as cubics with the advantage of a strong control on their shape, given by two degrees which play the role of design parameters. As a consequence, more flexible C 2 B-spline or NURBS like curves and C 2 tensor-product or Boolean sum surfaces can be obtained with the same geometric construction and the same computational cost of their cubic counterparts.

This paper compares two different ways of building B-spline curves and surfaces for even degree polynomial splines. Viewing these problems as digital filters, we find that one way gives better results than the other one. This paper is intended to be a reflection and a continuation of the paper "B-sp
