摘要：
In this paper, we give Bn explicit formula for converting a triangular Bezier patch into three nondegenerate rectangular Bezier patches of the same degree. The use of certain operators simplifies the formulation of such a decomposition. The formula yields a stable recursive algorithm for computing the control points of the rectangular patches. We also illustrate the formula with an example.
