Mattes (traveling and otherwise)

Yes - I seem to remember back in the spring when the subject
of "Reboot" and "Bump in the Night" came up, someone mentioned
that they had made a stereo pair of "Bump" via the dolly method, and
the backgrounds were *very* flat - they must have been painted
"backdrops" for the "Claymation" type figures...

I can see how worrying about 3D matte paintings would be a major
pain - I'm *presuming* that Toy Story used a fully modeled world
(to coin a phrase) but I don't know that for sure...I have to admit,
though, that occasionally I have laid a 2D image onto a 3D surface
to give a pseudo-3D effect (as in texture maps). Those fail 
pretty badly when rendered in stereo. On the other hand, if you
are dealing with a matte used to insert a "far off" visual plane
you might be able to get by using just one. But the matte used in
the Star Wars "death star hanger deck" (to mention one) probably would
not work very well in that situation.
