摘要
本文给出了一个保证m×n次参数Bezier曲面为凸的确定控制网格的简单方法,同时讨论了平面n次Bezier曲线的凸性控制问题.
In this paper, a simple method for determination control net of a parametric Bezier surface of degree m × n is presented, the control net that we obtained is not limited to the convexity of the control net, but the Bezier surface which is decided by the control net is convex. By the way, we discuss how to control the convexity of a planar Bezier curve of degree n simultaneously.
