We are talking about Non-uniform rational B-spline. We have some simple 3 dimensional array like

{1,1,1} {1,2,3} {1,3,3} {2,4,5} {2,5,6} {4,4,4} 

Which are points from a plane created by some B-spline

How to find control points of spline that created that plane? (I know its a hard task because of weights that need to be calculated but I really hope it is solvable)
