摘要
针对目前小波曲线曲面造型技术中几何约束条件难以保证的问题,提出小波信号分离的解决办法,将原始控制点分为与约束相关和不相关两部分分别加以处理,并给出其数学说明。在此基础上对曲线曲面造型技术中常见几种几何约束给出了较为详细的应用分析。从应用实例上看,这种方法取得了良好的效果。
In order to solve the problem of constraint condition changing with the application of wavelet techniques to curve-surface modeling, a method of wavelet signal separation, treating control points contacting or noncontact with constraint condition separately, is presented, and so has the mathematic analysis. Basing on the method some examples of constraint condition in curve-surface modeling are solved, and from the examples could be learned the method well done.
