摘要：

A theorem regarding the termination criterion for subdivision of triangular Bezier patch is presented with detailed proof. As the number of times for subdividing a triangular Bezier patch can be a determined prior, according to the given tolerance, the subdividing process can be conduced consecutively without checking for linearity after each subdivision. The theorem has potentiais in various CAD/CAM applications. (C) 2002 Published by Elsevier Science Ltd.
