                                     NurbsPatch

NurbsPatch describes rational and non rational Bezier surface.
It is defined by two degrees n and m and a matrix of control Points Pi,j
and using the parametric equation S(u,v) = Sum(i=0,n)Sum(j=0,m)(Ri,n(u)Rj,m(v)Pi,j) with u and v in [0,1]
where Ri,n(u) and Ri,m(v) are classical n and m-th degree rational basis function.
