some quads are not...  think boomarang-like... I think there is a technical
term for that class of quad... also think if a "bowtie", also technically a
quad but potentially having "negative area".

And quadralaterals aren't convex?  I don't get it.

Because triangles are convex they are guaranteed to be rendered correctly.
Every modern graphics system whether hardware or software is based on using
triangles as the basic element.

I'm not Marcus but in finite element analysis the discretization of a 2
dimensional region is always done with triangles. It's much more flexible
than rectangular grids, to oversimplify.

Marcus, 

Can you explain why the basic unit is a triangle?

Any Peircean would LOVE it.

I vaguely remember plot 3d. No one renders today the way it did. Cray was
less than a PC with a decent graphics card.

Let me revise that a little bit.  There was a visualization of the rider's
view of a roller coaster ride that ran on a Cray supercomputer.  The purpose
was to demonstrate the capability and speed of a Lisp-based 3D renderer
called Plot-3D or P3D or something similar.  Do you know what I'm talking
about, Ed?

You should take it seriously but I'm biased.  I don't think PSC let's its
supercomputers be used for eye candy.  They didn't when I worked there and
they were accountable to NSF.
