Chinese Abstract

根据曲面的延展量进行曲面分割,对分割后曲面进行控制点的反射对称,得到满足G^2连续的延展曲面。给出了散乱控制点的有序化的方法,有效地防止了拓展曲面产生折叠、起皱,实现了曲面延展设计的算法。

English Abstract

The paper presents the algorithms for NURBS surfaces of the continuous extension and bridge. The extension surface, which satisfies G^2 in continuity with the original surface, can be achieved by segmenting the original surfaces and then getting the mapping symmetric control points for each of the segmented surfaces. The method for regularly ordering the random control points effectively avoid folding and crinkling in the surfaces of extension and bridge. Programs have been developed using VC++ and OPENGL and the successful practical applications have also proved the implementation of the algorithms.
