You might look into something called the minimum norm network (MNN), which I
know nothing about except that it is used to do fit locally smooth surfaces
to scattered data such as you describe. It may have some relationship with
B-splines, but it is not the familiar B-spline representation and it does
not require uniform spacing. Search the web!
