He redefines and extends some graphics functions, and his ListSurfacePlot3D should do what you want. In cases where the surface height is supposed to be some simple function of the, but you have noisy, irregularly spaced data, a two-dimensional Fit[] could work for you. I'm not sure whether Interpolation would work for this kind of data set.
