摘要
本文讨论四次 Bézier曲线的保形性 ,对不保形的四次 Bézier曲线构造了一类四次有理 Bézier曲线的调整方法 ,论述了保形性定理 。
In this paper we disscuss the shape preserving of Bézier curve of degree 4.For shape preserving,a kind of rational Bézier curve of degree 4 is constructed.Then we prove some shape perserving theroms and give the algorithm and examples.
