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 Wink | ;)

Don't hit me if I say something stupid, but what in the name of all that is good do these two commas separating the three expressions mean?
Curiosity levels are rising.

Look here:

Bspline in C#[^]

That should help you.

Close Valery, but no cigar yet. OP needs to draw a spline for some (not precisely defined) parametric function.

Manfred has a good eye for details...
And thats (any parametric function) exactly the biggest problem for me...
