I am currently working on a java prog that generates Povray files from a
digital elevation map of our little planet. Now I usually end up with a
mesh containing several millions of triangles and it takes REALLY long
for povray to parse one of these. 
Is it possible to declare triangle strips instead of individual
triangles? That would reduce the size of the povray-files and it could
also help with increasing parsing speed/decreasing memory requirements.
I would also like to render animations without having povray parse the
mesh for each frame. Is there anything I can do to make povray just keep
the mesh in memory instead?
Are there any 'unofficial' povray versions out there that could help?

thanx a lot
 Edmund

  You should use the mesh2 format of MegaPov (and povray 3.5). Check

  Yes, MegaPov can do that.

Thanx, thanx, thanx!
I'll take a closer look at MegaPov....
