【摘要】 简述非均匀有理B样条曲线、曲面在车辆外形设计中的应用方法,推导了基于物理模型的曲线曲面构建方法,进而获得了产品造型所要求的曲面,并在CAD领域的工程实际应用中进行了探索。实践表明,应用NURBS曲面使产品造型设计者能随心所欲地实现自己的设计意图。更多还原

【Abstract】 Introducing briefly Non-Uniform Rational B-Spline method of vehicle body curves and surfaces, deducing curves and surfaces construction method based on physical model, achieving required product modeling surfaces, and exploring engineering practical applica- tion in CAD field. The result indicates that product modeling designer can realize freely project intention based on NURBS surfaces.更多还原
