I have created a program in MATLAB that creates a b-spline surface from a set of (x,y,z) points. I would like to see if my program works before I develop it into a full program (user interface plus lots of options). Here's what I'm asking... Could someone generate a b-spline surface of degree 2 in both the u and v direction. Let's make the number of (x,y,z) control points 4 in both the u and v direction. I'm not sure what software will make a b-spline surface for you with the option to change the degree. This would be very helpful. I would like to finish this so that I can post this program here.
