I just sent a similar question in last week. This is basically the functionality I'm looking for too. In MATLAB this can be done with the trisurf plotting function. Matplotlib has a plot_trisurf method for an axis provided by loading the mplot3d module, but as far as I can tell, you can either give a surface a constant color or you can choose a cmap and have it color the surface according to the Z values of surface points.
If anyone knows of a way to make Philippe's plot with Matplotlib, I'd love to know.
