Abstract

Direct and converse approximation error estimates for generalized Shepard operators are given, improving analogous inequalities for well-known Shepard operators. As application in CAGD, generalized degree elevation algorithms for modeling the shape of Shepard-type curves are presented, improving previous techniques.
