| 摘 要： | 本文给出一种用圆弧逼近三次平面Beziter曲线的算法,该算法的特点是能保持曲线的整体光滑性,所用圆弧数量少,并可对逼近精度进行控制,该算法稍加变化后也适用于用圆弧逼近其它类型的平面曲线。

| Abstract: | A method on the biarc approximation of cubic Bezier curves is described.It aims at maintaining the smoothness of the resulting curve and reducing the number of arcs required for a given precision.This method can also be adapted to approximate other types of planar curves. |
