摘要
根据作者采用重节点非均匀Ｂ样条方法进行汽车车身计算机辅助几何造型初步实践，介绍了实现车身ＣＡＧＤ的主要技术即车身表面曲线曲面的构造方式，并给出了基于该技术的造型实例。由于Ｂ样条的局部性、直观性和保凸性等优点，引入了重节点技巧，使作者基于该方法所研制的软件具有较强的曲面造型功能。
Based on the authors initial practice in applying the multi-knot nonuniform B-spline method to computer aided geometric modelling of automobile bodies, this paper introduces the main techniques of designing the car body computer-aided geometric design system, i.e.the methods of modelling car body curve and surface. The software system designed by the authors had strong functions of surface modelling.
