基于NURBS的曲面造型技巧

NURBS-based Surface Modeling Techniques

随着产品外型越来越向＂流线型＂方向发展,因此在整个CAD的建模过程中,自由曲面造型所占的比例越来越重。同时,要求自由曲面的造型必需能够局部地自由加以变更,使其符合各式设计需求。结合曲面造型的工作实践,对利用NURBS进行曲面造型有关的理论与技巧和经验进行探讨。

With the direction of the product becoming more and more similar to the streamline,in the CAD modeling process,the proportion of the free surface modeling becomes more and more important.Meanwhile,it is required that the free-form surface modeling must be able to change the freedom of local and meet all kinds of design requirements.In this essay,I use the working experience of surface modeling practice,to do a study for the use of NURBS surface modeling theory and related skills and experience.
