Thank you for your reply
yes I know the mathematical relationship of the control points to the interpolation points, but to resolve the system i need more equations to find control points, for example if i have 3 interpolation points i need more equation sto be able to find controle points, please if you can give me a quick description of the solution then i can implement it my self or giving me a peace of code will also help me :)
Best...

Hi everybody,
i wish i will get an answer here i was looking for so long to find a solution to my problem this is it :
i have a grid of interpolation data points (x, y, z) and i want to know how to find control points for a cubic b-spline that passes exactly on all my interpolation points.
please help me
if you can also give me an algorithm in c++ for doing this
with best regards
