Curvature continuous blend surfaces
We describe a method to generate blend surfaces which fit with continuous curvature to the primary surfaces. This blend surface is obtained as the bicubic tensor spline minimizing a variational problem. Among all the bicubic tensor splines which give a curvature continuous blend surface, the one is chosen which minimizes a bilinear functional. In Section 2 we summarize and extend the results of a previous paper in such a way that they are applicable to our problem. In Section 3 we outline in detail the procedure how to generate a blend surface based on these results.
