IIRC, Exluna was formed by two people who left Pixar,
so it is not unreasonable to believe they actually took
some techniques with them. Probably fast anti-aliasing
algorithms that they wrote, but Pixar "owned". This is
a real problem in academia too. If you invent something
while you are a grad student or post-doc at a university,
the University owns it. So wait till you're on your own
before you publish it!

I find that this is the most important part of this thread.

Larry Gritz is hardly just someone at Pixar, he is the author of the
Renderman shading language. Without him, Pixar would have been nowhere
near where they are today.
I find such legal issues particularly appalling and driven by green.
No wonder Al Pacino had a layer's company in "Devil's Advocate".

I guess you meant "lawyer", cause "laying" someone
is a totally different matter... ;-)

"Advocate" also comes from the same root as "lawyer" in a number of
languages, including Spanish (abogado).

Yes, the language many other languages inherited it from is Latin.
