三维数据点列的拟圆柱螺线样条插值
INTERPOLATING 3D DATA WITH QUASI-HELIX SPLINE
-
摘要: 提出了用拟圆柱螺线来插值三维空间有序数据点列的一种方法,该方法对数据点列没有任何限定性要求.分两步求解,先求空间曲线在固定平面上的投影曲线,再求整体空间曲线.无论是闭曲线还是开曲线,都能达到整体G1连续.Abstract: A method for interpolating 3D data with quasi-helix spline is introduced．The approach is very robust for handling any 3D data set．Global G1 continuity can be attained no matter whether the spline is open or closed．
