You mean something like:

Syntax may be subject for a new discussion.
So, if (camera is positioned above the lower edge of the object && !(32 < colour < 47) ), interior can be skipped.
Pardon my bad pseudo-code.
Whether studs can be skipped or not, well that's a tough one...

It sure is. What about viewing a scene where all parts of one kind, say all 3001's are red, and all the rest gray? Then
you get a list wher you can uncheck those that need to be completely drawn. And the unchecked turn green. Uhm well...
Maybe.
Despite TLC's part specialization mania and the fact that only 57 of the 1583 parts in my LDraw\Parts directory are
standard bricks/plates/tiles, those parts still dominate at least my projects. I think very much could be won by just
simplifying those 57.
