Using dv3d to display 2D flying carpets?

[chaosphere2112]

@ThomasMaxwell , one of our users told me yesterday that he wanted to use paraview to use 3D to display a 2D field with the surface elevation he his using in his model. He works on very very very ancient climates, with continents very different from now, and he would like to be able to show them easily to other people

So I guess it would be useful to be able to plot some kind of flying carpet from a 2D field with DV3D. Kind of the following matplotlib example

http://matplotlib.org/examples/mplot3d/trisurf3d_demo.html

Some potentially useful options to be considered:

• determine how far above the dv3d earth map the surface should be plotted
• determine the height of the surface (map from the actual surface data range to the displayed height in the dv3d window)
• display the 2D field in shaded or wireframe mode
• color of the surface can be: constant, based on the 2D field itself, based on another 2D field

There may be some other things from the matplotlib 3D examples that could be useful for climate data users (people having a 2D cdms2 variable)
