rational interpolation curves的意思|示意

The error estimation of rational cubic spline with linear denominators is given, and then the interpolation of a kind of space closed curves under cylindrical coordinate system is investigated.

给出了具有线性分母的有理三次样条函数的误差估计，并在柱面坐标系下对一类空间闭曲线的插值问题进行了研究；

A local interpolation method is presented by using the cubic non-uniform rational B-spline curves. The generated interpolation curves can be C2 continuous and have a local shape parameter.

利用三次非均匀有理b样条，给出了一种构造局部插值曲线的方法，生成的插值曲线是C2连续的。
