摘要
在船体外板的曲面拟合中,基于NURBS样条曲面的优点,采用NURBS三次样条插值函数方法,针对测量给定的离散数据,建立了相应的数学表达式;并利用在AutoCAD中的VBA编程技术,以某实船的一外板为例进行了曲线、曲面的拟合,得到了比较满意的结果。
Considering the advantage of NURBS spline surface, a method for NURBS interpolation function is introduced to the modeling of ship hull plate surface. With this method, corresponding mathematical expressions can be established with given discrete data. By the use of VBA programming technique in AutoCAD, an example on the curve surface fitting of a ship hull plate is presented, and the result is quite satisfied.
