THE CUBIC RATIONAL BEZIER CURVE DETERMINED BY TWO POINTS WITH CONVEX HULL PROPERTY AND CONVEXITY PRESERVING PROPERTY
由两点确定的具凸包性和保凸性的三次有理Bézier曲线

This paper shows that under a necessary and sufficient condition, there exists a cubic rational Bezier curve with convex hull property and convexity preserving property which passes two given points inside the control polygon.
