The shape of objects used in engineering applications reflects both functional requirements and manufacturing processes. In particular, surface blends can be designed to satisfy functional requirements such as hydrodynamic or structural performance specifications, or they can be a byproduct of milling of concave corners of solid objects. In either case, a blend is a surface which forms a smooth transition between two distinct, but intersecting surfaces or smoothly joins two or more disconnected surfaces. In this paper, a method for accurate and efficient approximation of blending surfaces which are curvature continuous to the underlying parametric surfaces, with a non-uniform rational B-sline surface is presented.
