Please, tell me how to do it. There are at least three methods. Firstly, you can use functions in DiscreteMath`ComputationalGeometry`. In V4, it comes with the online help. For V2.2, Shaw & Tigg's book runs through the gory details. The second method is to use functions in Wickham-Jones' ExtendGraphics` package. This is on MathSource. If neither of these appeals, try ListSurfacePlot3D. This one lives in Graphics`Graphics3D.
