Finding a polynomial least-squares surface fit is mathematically straighforward, but there is a huge tendency to "over fit" the data. For an irregular mesh you would probably need to re-intepolate to a regular mesh (Delaunay triangulation, followed by re-interpolation to a quadratic grid) I already have code for all this, as engine maps and geographical maps need many of the same tools. -- atp The idea that there is no such thing as objective truth is, quite simply, wrong. ------------------------------------------------------------------------------ Learn Windows Azure Live!
