On linux, I generate .tga files from povray, and make them into a movie
using mencoder, which comes with mplayer (the "do everything" media player
out of Hungary).  

On Windows, I generate .bmp files from povray, and use a free utility called

An advantage of the mencoder route is it'll compress to DivX directly (or is
it MPEG4? -- in any case a very tight/compressed format), whereas on
Windows, the .avi output files are simply huge (like 300 meg), meaning I
need to compress them further with Dr. DivX (comes out about 1.5 meg) --
proprietary and paid for.

Examples of the animations I'm doing with Python + Povray are at
ftp://www.4dsolutions.net/pub (the raw data comes from sensors strapped to
the body of a dancer, who does her moves while a numbers stream to a file --
which files I get, after cleaning, in spreadsheet format).

However, in order to view them, you have to be able to play DivX -- a codec
Windows doesn't come with natively (mplayer on linux should have no
problem).  A solution is to download the (free and open source) VLC player
from Videolan (www.videolan.org <-- .org, not .com).  This will play the
animations at my ftp site.  There's an OSX version of VLC too I think.
