I've thought about this also. A while back we discussed adding a feature
that would remember the file and line number for each pixel in an
LDLite-created image.
You could use this information to strip out non-visible lines
before exporting to POV, assuming camera angles were the same.
It would probably help a lot on huge scenes, and would not be too
much of a processing hit in an L3P-style program where the files
are all stored in memory and could easily have a "in-use" bit added.
LDLite 1.6 will have a new "trivial rejection" optimization, where I check
to see if the closest vertex of a triangle is closer than the farthest away
zbuffer values in that region, and if not the triangle is skipped over
before many of the computations are done. There are a lot of polygons
that fall into that cataegory in your typical LDRAW image.
