摘要
介绍了直线逼近和圆弧逼近2种NURBS曲线逼近算法,并在两者的基础上,提出对NURBS曲线进行混和逼近的新算法,最后,通过实例验证了该算法的正确性与可行性。
Introduced two kinds of arithmetic of approaching to the NURBS curve i.e. beeline approaching and circular arc approaching. Based on the both, present a new mixed approaching method which synthetizes them. At last, the method is proved to be correct and feasible with an example.
