Abstract
An efficient algorithm is presented for modeling closed surfaces with bicubic Bezier patches. Starting from a control polyhedron with four-sided faces (not necessary planar), the algorithm fits the faces of the polyhedron with bicubic Bezier patches which are globally G1 connected. Methods for controlling and modifying the smooth closed surfaces are provided by adjusting certain weight factors. The proposed method is capable of dealing with control meshes of arbitrary topology and offers a simple and convenient way for modifying the shape of smooth closed surfaces locally and interactively. Experimental results demonstrate the potential of our method.
