Not sure I'm following.
Are you looking for ray tracing efficiency?
If after a result, in addition to Alain's suggestion I'd add the
clipped_by mechanism where only surfaces inside the clipped_by shape
show up.
Underneath today everything is textured - carries that overhead - no
matter.
I've been playing with the idea of independent
containers/shapes/surfaces and bounding structures for textures,
interiors and so on rather than hanging everything off the shape
surfaces. Only a few experiments in that direction thus far (the maze
isosurfaces posted months back was one in part).
