Blending Circular Quadrics with Parametric Patches

摘要：

A method of blending circular quadrics with parametric patches is proposed in this paper. It needs n rational bicubic Bézier patches and two S-patches to blend n (n>2) quadrics. The blend is G1 continuous. Explicit formulae of control points of both Bézier patches and S-patches are derived from the corresponding G1-continuity conditions. In addition, the shape can be intuitively modified by adjusting the free parameters of the blending surfaces.
