The drama in her songs surfaces smoothly and irresistibly; in songs like "Fiori d'Arancio" ("Orange Blossoms"), about a bride abandoned at the altar, she reached startling peaks that were never forced.
However, it is difficult to interpolate the area of curve meshes with NURBS surfaces smoothly.
In the free-form morphing, control points are obtained by data mining, and then mesh subdivision is applied to refine surfaces smoothly.
In this paper we will investigate in more detail the case of canal surfaces that are often used in geometric modelling, Computer-Aided Design and technical practice (e.g. as blending surfaces smoothly joining two parts with circular ends).
By assigning suitable knot vectors to the head and tail skinned curves, the semi-structured B-spline surface can blend two B-spline surfaces smoothly without disturbing them at all.
This article presents a multi-block CST method after analyzing the mathematical description of the method, and this method joins adjacent surfaces smoothly and retains the good properties of the CST method.
In our experiment, the surface was smoothly finished.
Between these three areas, the slab surface was smoothly interpolated.
We contribute to this problem area by showing how to approximate a negatively curved surface by smoothly joined rational bilinear patches.
