Fred,
>… you could build ANYTHING out of triangles, so it may be better to work on
an engine thet ONLY draws fast triangles. Or maybe also fast squares.
From my rudimentary knowledge of integral calculus, the statement about
triangles is true. This is a method used to calculate area and volume of odd
shapes. As to the use os squares, that doesn't really sound practical to me. I
could be wrong though, I frequently am! <G> Seriously, you could use
rectangles, and make them sufficiently small, but you would still have an
inherant error (actually, +- [(upper riemann sum – lower riemann sum) /2].

This I guess would depend on the hardware. For instance I know that
some SGI models have hardware acceleration for this kind of thing and
some do the same thing but emulated in software. overall, i would
guess that if would come down to how complex the thing you are trying
to represent is. Im thing that with a 'simple' enough model then
triangles would be fine, but if the model were 'complex' then any
gain you might get in comptation would be offset by the task of
calculation and keeping track of so many triangles. Just a thought.
