Curve and surface constructions using rational B-splines. (English) Zbl 0655.65012

Summary: This paper presents the non-uniform rational B-spline approximation form as a unified approach to representing free-form as well as standard analytic curves and surfaces commonly used in CADCAM. The emphasis is on geometric constructions, not on the underlying mathematical theory.
