you can run that on a Linux box?

had not known of this either.

self prefers small, dedicated tools.  the source linked ('gts2pov'[*]) builds a
small and reasonably quick executable, used for these:
<http://news.povray.org/povray.text.scene-files/thread/%3Cweb.5e1881adbbdf84bb8c662f470%40news.povray.org%3E/>

to compile:

  $ cc -std=c99 -pedantic -Wall -Wextra -O2 -fPIC -o gts2pov gte2pov.c

edit line 40 to raise the maximum vertices per mesh, default 1M.

that does sound, um, a little masochistic.  :-)

the user ought to have choice of 'mesh' or 'mesh2', imo.
