摘要：
In this paper, subdivision methods for rectangular Bezier surfaces are generalized to subdivide a rectangular Bezier surface patch of degree n x m into two rectangular Bezier surface patches of degree n x (m + n), while the parameter domain of the Bezier surface is decomposed into two trapezoids. As an application, a conversion from rectangular Bezier surfaces to triangular Bezier surfaces is presented. (C) 1996 Academic Press, Inc.
