Check out the NVIZ tutorial.
http://grass.baylor.edu/gdp/nviz/nviz_tut.html

especially: Basic Animation and Key frame Animation sections.

This has been updated for GRASS 5.3 & 5.7.

Also try compiling "d.nviz" in src.contrib/GMSL/


If you make a symlink from 'ppmtompeg' to 'mpeg_encode' somewhere in 
your $PATH, r.out.mpeg will work, but this is MPEG-1 and not that great. 
For more MPEG-1 and MPEG-2 support you can use The GIMP; or for high 
quality & modern MPEG-4 and others try mplayer's mencoder or the ffmpeg 
encoder. For high quality animations you can play in any web browser 
(limited to a few hundred frames) use "gifsicle".

The netpbm programs are useful and will be needed between steps...

If anyone knows how to do animated PNGs I'd be interested in how that 
is done..?
