摘要
综合目前NURBS插值与拟合技术，给出了完整的NURBS曲线生成方法，将权因子优化与反求控制点有机地结合起来，并且对权因子的选取与边界条件的确定进行了有益的讨论。利用此方法生成的NURBS曲线可控性强，灵活简便，同时为NURBS曲面的生成奠定了坚实基础。
The systematic method of creating the NURBS curve is presented on the basis of the technique of interpolation. The optimization of weights and searching control points are integrated organically, and the selection of weights and definition of boundary conditions are explored. The NURBS curve created by this means can be controlled easily, flexibly and conveniently. At the same time, the method can be viewed as the fundamental step of the NURBS surface.
