I have some "sparse" 3D data in the form of X, Y and Z vectors, X and Y are plane coordinates and Z is the elevation. Like in the mathcad help example about quick 3D data plotting, I can obtain a scatter plot of that points fine. I can then convert that plot in a surface plot and also add interpolation on the displayed mesh (both over- or sub-sampling actual data). My question is, is there a way to export that interpolated data for further use? Or is there an easy way to fit my 3D data to a regularly spaced XY grid?
