如何评估b样条 [英] how to evaluate b-spline

问题描述

大家好.
我对b样条曲线有疑问.我不知道如何从参数给定函数F(t)=(-1-cos(t)，2t-sin(t)-2PI，0)中评估b样条.

我不知道我的控制点应该是什么，或者如何获得它们...
进一步，我不确定如何为这种给定功能获取混合功能...

如果有人知道此主题，请非常感谢您的帮助.
P.S.抱歉语法不好;)

Hello all.
I have a problem with b-splines. I dont know how to evaluate b-spline out of parametricaly given function F(t)=(−1−cos(t),2t−sin(t)−2PI, 0).

I have no idea what should my control points be, or how to get them...
Further on, im not sure how to get blending functions for this kind of given function...

If there is anyone who knows this topic well id be verry gratefull for your help.
P.S. Sry for bad grammar ;)
