1)convexity preserving property保凸性
1.This paper shows that under a necessary and sufficient condition, there exists a cubic rational Bezier curve with convex hull property andconvexity preserving property which passes two given points inside the control polygon.但由两点确定的三次有理 Ｂｚｉｅｒ曲线的权因子不一定非负，从而不能保证曲线具凸包性和保凸性，而无论从理论还是实用角度看，曲线的这两个性质都是很重要的。
