摘要
主要讨论了平面参数曲线求交的迭代算法,提出了迭代过程中迭代可信度的概念,并给出了计算方法.在此基础上,改进了MAF求交算法,给出了曲率圆迭代算法,即使用二次曲线对参数曲线的局部形状进行近似,进行迭代交点和迭代步长的计算.
In the intersections of parametric curves, this paper presents the definition of iteration reliability and its computation. Based on the ideas of iteration reliability, this paper improves the MAF algorithm and present curvature circle iteration algorithm by using the second order approximation of the curves.
