车身外形曲面CAGD系统的开发与应用

The development and application of CAGD system of curve shape of bodywork

在分析车身外形曲面设计规律的基础上 ,从NURBS方法的原始定义出发推导了具有实用意义的算法 ,并建立了用于车身外形曲面几何造型的CAGD系统 ,最后给出了设计实例。

Based on the analysis of the design law of curve shape of bodywork,an useful calculative method is derived from NURBS defintion,and CAGD system that is used in the geometrical sculpt of curve shape of bodywork is set up.
