摘要
B样条曲线、曲面是计算机辅助汽车车身造型的一个重要工具。对目前常用的几种B样条曲线插值方法进行了讨论，并提出了一种新的B样条曲线描值方法──构造曲率法。设计者可通过调整该方法中引入的曲率参数K，灵活地改变端部形状，使之合乎设计要求。最后，给出了应用实例。
The Be' zier curve and surface are important means in computer aided car body surface styling. The article discusses the interpolation method of Be' zier curves frequently used nowadays and put forward a new interpolation method of Be' zier curve-the constructional curvature method. Designer may modify flexibly the end form by adjusting the curvature parameter K introduced in this method to meet the design requirament. Application example is finally given in the article.
