For examples of camera movement look at

In the next MegaPOV there will be another types of splines available which can
result with more interesting paths.

Thanks for that link. Yes, the POVray scripting language has grown over the
years and I can see the problems here.

My model is simply constructed from a list of explicitly defined primitives,
so there is no looping or anything like that. In this case the problem would
be converting the POV primitives to triangle meshes. I had wondered if a
utility existed to do this, but I do agree that for the more general case it
would be even more difficult.

Thomas Baier has written a few utilities to do this with early versions of Pov.
You might be lucky.

Thanks Steven. Looks promising. This page lists POVRAY 3.5 and MORAY formats
supported:

If you don't have Moray, it can export UDO and RIB files. I've not tried it
though.

TriScan Macro, maybe.

Using a patched povray, you could tesselate and save your objet in gts 
format.
See http://jgrimbert.free.fr/pov/patch/tessel/index.html
in particular gts_save

BTW, have you done (or planning to do) adapting that patch to POV-Ray 3.5
?

No planning for 3.5 so far for me, but you're free to move it to 3.5 and 
even to enhance it (using the functions of 3.5 is propably the most
interesting enhancement). Just beware of the marching-cube patent, if it
apply to you...

It's quite high on my priority list but since it is quite a large patch it
will probably take some time...

I know.  The main problem seems that no one knows how broad these patents
are.  It it's just about disabling one or two of the tesselation methods
that should not be a problem.  If on the other hand the patent owners
could claim all grid based tesselation methods are covered this would
apply to all tesselation methods of that patch.
