VT-Mak's VR-Vantage product is OpenSceneGraph-based, and it does in fact
support CIGI... They told us we'd have better luck using DIS or HLA (their
specialties), and weren't in a position to demo CIGI capabilities to us...
It's actually a pretty great product, otherwise, and we told them if they'd
of showed up with it five years ago we never would have developed our own
solution. :)

As far as a multitude of IGs supporting CIGI... Well, here's hoping. As I
said before, our experience was that the vendors we spoke w/ had CIGI on
their buzzword list in the product literature, but when it came down to
actually using it they'd get kind of cagey and direct us towards their own
protocols... More competition should help that attitude a lot. :)

That reminds me, when we wrote the OSG-based our deferred renderer for our
Image Generator, we got FAA sign-off for releasing it to the community. If
other people are looking to work on IGs, a solution for massive amounts of
dynamic lights might be helpful. It's a little outdated, and needs a lot of
cleaning up, but it's a starting point... Does anyone think it'd be worth
my time to clean up (the curse words in) the code and improve the
documentation so it could be released?
