Check out the NVIZ tutorial.
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
