I'm rendering a scene right now that has over 130 million triangles and
the parse time for just the mesh include files is about 8 minutes on my
1 ghz machine. Add in texture computations, radiosity, area lighting,
the trace function and few other things, the total parse time is around
12 min. I would hate to do that for every frame of an animation...!
