Dear all,

I'm a new user of POVRAY.

Now I'm gonna use POVRAY for visualizing ground motion on the surface of the
Earth. The computation results give us a 3-D volume of ground motion amplitudes,
and I want to show these amplitudes on topography and subsurface. I found the
figures on the internet and these are exactly what I want:

For 2-D array:

For 3-D volume:

Now I can draw topography and sea floor, but I have no idea for visualizing the
seismic wave. My question is, which functions should I use for this purpose,
including visualizing 2-D and 3-D datasets?

Thank you.
Best Regards,

M.-C. Hsieh
