This is possible, but you would loose most of the benifit of "caching" the
previously rendered images, since there would be so much freedom. I'll start
with adding larger jump options for the movements. By keeping those factors of
50 it won't create new views. I would also like to have relative controls
(left,right, forward, reverse) instead of n,s,e,w. That would add significant
calculations to the shell script and would probably require moving it to C.

That's actually not that hard to do.

Ok, I'm just learning povray syntax so I'll look at it.
does "amb" work everywhere? even inside closed spaces?
right now I'm using one light source in the "flashlight" position.
That's the only way I know to guarantee ilumination in every space.

Well, you could manually change the hyperlinks to call the appropriate
model name (http://www.brickshelf.com/cgi-bin/mkpov.cgi?model=grnhouse would
call up the green house model).
Currently adding a dat file requires running it through l3p, which only
runs on wintel. After that I strip everything after the object line,
and an entry has to be made in (internal) models.txt with the model name,
starting coordinates and look coordinates, url for linking to source, etc.
That's not exactly an automatic process. I suppose if l3p was ported to
FreeBSD I could automate it with a temporary model name.

It is definately not view dependent. I'm going to go through the povray
source and figure out what if anything can be saved to a binary file after
parsing to bypass those steps in subsequent rendering.
