Degree of the B-spline surface

[Jiahao-Ma]

Hi Jinhui,

I find that you provide us with the coefficient matrices. Could you please tell us the degree of the B-spline surface (two degrees in u and v direction)? As you know, the degree of the B-spline surface is important for us to calculate the coefficient matrices.

Cheers,
Jiahao

B-spline surface is a 4-by-4 patch spam in u and v direction. Cubic itself is a 4-th order representation.
