Then it might be too exoteric, but it would benice to generalize Interpolation2D to accept a policy (x_first or y_first) and (possibly) different factories for the x and y axis, so that your new Polynomial2DSpline (and the old BicubicSpline, BilinearInterpolation too) would just become typedefs ciao -- Nando |
