If I understand the question correctly, and from my understanding of how a ray-
tracer works, Pov-ray must keep all polygon data while it renders since it
"traces" all the light rays, even those that you can't see (inside of a brick).
It doesn't clip the top/bottom/left/right or eliminate backsides, or z-buffer
until it has done all the lighting calculations.

Ldraw has a ton of extra polygons compared to Unreal or Quake. It would be
possible to optimize a model by writing a utility that does it's own "ray-
tracing" and eliminates all polygons that don't see the light of day. However,
this is a big project, and is way over my head.
Just my 2 cents.
