Hello, I'm new in this hole API world, so I really don’t have a clue of what to do, doing a little research I see that there are several languages to program an API, I personally want to do it in C++, because I'm also learning how to program in this language.

So ok... What I’m trying to do, is creating a program, witch creates a parametric surfaces using nurbs, but for doing this I need to give to the program a .txt, this file contains the information of the point in x, y and z normal coordinate, in a Nx3 data set, I also have to give to the program how many points are there in a MxN way...

What I'm looking for is some guidance, not a complete program!

Thanks for giving me some attention and sorry for being such a noob!
