Those are interesting pics (and very neat, too).

Your experience with complex scenes is
of great help in this discussion.

I'm curious as to what the memory usage
is like on your computer when rendering
these scenes, and how you would handle
getting previews of such scenes
(either stills or test animations)
and how long they would take.

I should also clarify that I'm not
necessarily beholden to scanline rendering
as the goal per se, but rather to just
find the best way to handle complex scenes
and achieve fast previews (and also to
shorten render times for scenes that
don't need global illumination effects).
I think getting fast animation previews
was the driving factor behind Renderman,
for example, because for any given
film scene one has to rehearse it
a few times.

When you say that your triangles are
non-instantiated, are you saying that
they are merely pointers to a master triangle?
If so, do I assume correctly that their
transforms are also in common (because
if they weren't, then each triangle would
have to store a 16 element matrix)?
