I understand that. But the question specified that the number of triangles
(actually polygons, but feel free to assume triangles) is fixed.

So size of the polygons doesn't matter. Hmm. I'll have to remember that.

| (...) Well, it can matter, but isn't likely to in a LDraw renderer. It would matter if the program ever became fill-rate limited, but that usually won't happen, except with very simple models. --Travis Cobbs (tcobbs@REMOVE.halibut.com) (23 years ago, 4-May-02, to lugnet.cad.dat.parts.primitives)
