摘要
提出了点集Bézier曲线的概念,给出了点集Bézier曲线的性质及细分算法.按照点集算术的定义,当点集是长方形闭域或圆盘时,点集Bézier曲线就是区间Bézier曲线或圆盘Bézier曲线,因此,点集Bézier曲线是对区间Bézier曲线和圆盘Bézier曲线的推广.
The definition of point set Bézier curves is put forward. The properties and subdivision of point set Bézier curves are given. When the point set is rectangular close field or disk, the point set Bézier curve is interval Bézier curve or disk Bézier curve, according to the definition of the point set. Therefore, point set Bézier curve is generalization of interval Bézier curve or disk Bézier curve.
