| Abstract: | 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. |
