改进的有理Bézier曲线离散终判准则

Rational Bézier Curves and Improved Discrete Termination Criterions

利用一些基本的不等式,按照求导法则,对Bézier曲线和有理Bézier曲线的高度估计进行改进,同时对有理Bézier曲线的离散终判准则进行了优化,最后利用极值问题验证了改进准则的有效性.

In this paper,some basic inequalities are introduced,the height estimation of Bézier curve and rational Bézier curve is improved according to the derivation rule,and the discrete final criterion of rational Bézier curve is optimized.At last,the improved criterion in this paper is validated by using the extreme value problem.The validity of the proposed method is verified by experiments.
