摘要
本文介绍了NURBS曲线、曲面的数学表达,给出了NURBS曲线和曲面的构形原理,在此基础上,推导了过渡曲面,进而获得了产品造型所要求的曲面。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。
Mathematics formulas about NURBS curve and NURBS surface are presented. Forming principle of them are also introduced. Based on these, some blending surfaces are inferenced and required surfaces of product moulding are gained. Practice shows that applying NURBS curve and NURBS surface make designers to be able to achieve product moulding as their pleases.
