摘要
介绍了非均匀有理B样条(NURBS)曲面模型,并分析船体型值表中数据的特点,利用NURBS曲面插值算法,提出了对船体曲面进行NURBS表达的方法.对节点矢量计算及边界条件构造进行了研究,并利用OpenGL函数实现了船体曲面的三维显示.取得的效果具有较好的光顺性.
This paper introduced Non-Uniform Rational B-Spline (NURBS)surface model, and analyzed the characteristic of ship mold data.Taking advantage of NURBS surface interpolation algorithm, it put forward the method of expressing ship hull with NURBS surface and researched how to construct the knot vectors and end conditions. Finally,the paper realized the ship 3-D display using OpenGL function and the results had good fairness.
