✦ Synopsis

In this paper, subdivision methods for rectangular Be ´zier

A rectangular Be ´zier surface of degree n ϫ m can be surfaces are generalized to subdivide a rectangular Be ´zier surface patch of degree n ؋ m into two rectangular Be ´zier sur-represented by face patches of degree n ؋ (m ؉ n), while the parameter domain of the Be ´zier surface is decomposed into two trapezoids. As an application, a conversion from rectangular Be ´zier sur-

faces to triangular Be ´zier surfaces is presented.

Using the same technique as for the C-B-splines, two other forms of C-Bézier curves and a reformed formula for the subdivisions are proposed. With these new forms, C-Bézier curves can unify the processes for both the normal cases, and the limiting case (α → 0) with precise results. Like the C-B-spli
