准均匀B样条曲线的局部多分辨编辑

Multi-Resolution Denotation and Edition of Quasi-Uniform B-Spline Curve

论文通过节点插入算法,首先对原始的B样条曲线进行分裂,把想要修改的那一部分曲线段单独表示出来;然后,对此曲线进行多分辨编辑,给出了局部多分辨编辑后各曲线段C1或C2连续性拼接条件。最后给出了图例。

Based on node-inserting algorithm,this article splits the original B-spline curve and denotes independently the portion of the curve that needs to be modified.Then ,multi-resolution edit the curve and discuss the continuity join of curve,a C^1 or C^2 continuity join condition of curve segments is given after local multi-resolution edition.
