利用ObjectARX实现B样条船体曲面的造型

B-spline Ship Surface Modeling with ObjectARX

从 B样条的基本理论出发 ,结合船体曲面构造的特点 ,提出了利用 Object ARX开发工具和准均匀有理 B样条理论在 Auto CAD中进行船体曲面造型以及进行后续处理的方法 。

In computer graphics and CAD application,designing complex shapes with free curve and surface is a difficult problem to solve.After making a comparison of the basic theories of free curve and surface and analyzing the characteristics of ship body,this paper provides a method of hull modeling in AutoCAD with objectARX,based on quasi uniform rational B spline.At last,the possibility of improving the quality of model is also talked over.
