You have to store scenes as well. As someone from Pixar recently wrote
in c.g.r.renderman, average scene description size is 500 MB and big
scene is 2 GB (compressed!) per frame!. Add to this texture maps, which
could take even more space. This of course applies to RIB format and 
perhaps POV-Ray will not require such amount of data. 
(I think that you can't avoid texture images, if you want to render fast
and good scenes: ARM describes, how folks in Pixar at first wanted to
create all textures as procedural, but this proved to be too
inefficient).
