摘要
本文研究了连续的双二次曲线 ,给出双二次曲线样条的构造方法 .本方法适用在一些特定点上给定相对曲率并要求整个样条曲线 GC2连续的一类问题 ,采用双二次曲线样条得到的样条曲线具有较好保凸性能 .
In this paper, GC 2 dual quadric curve were studied. A construct scheme of dual quadric spline with GC 2 was given. It improved biarc interpolation and dual quadric interpolation. The method could use to solve to the problem of the special point with given curvature and other point with C 1 . The spline curve of convexity preservig was very good, since it used dual quadric spline.
