基于小波的B样条曲线多分辨表示及编辑

Wavelets-Based Multiresolution Representation and Edit of B Spline Curves

多分辨表示方法为曲线提供了更为灵活的表达方式 ,使得我们可以在不同分辨率下对曲线进行编辑 .小波技术是实现曲线多分辨表示的一种新颖方法 ,已有许多论文从理论上论述了这项技术 .文中从几何概念出发 ,由浅入深地论述了基于小波的准均匀三次 B样条曲线多分辨表示的原理及其实现 ,并通过实例描述了

Multiresolution representation provides a more flexible approach to edit curves and surfaces in different resolution levels. The paper describes, from the viewpoint of geometry, the principles and methods of realizing wavelets based multiresolution representation of quasi uniform cubic B spline curves. An example is given to illustrate the editing of B spline curves in multiresolution level.
