This may be superfluous, but anyone not having visited the Orion flythrough at http://vis.sdsc.edu/research/orion.html yet, should really do so.
It is awesome.

Awesome indeed!

Thanks for the link Paul.

Wow. That's dead cool!!

This is well worth looking at. Don't let the large (21MB or 29MB) download file sizes for the movie put you off!

All the best for 2004.

Amazing! I just wish they had mentioned how they came to know the 3D stucture of the nebulae. Can this voxel thing be done with OpenGL?
Is there any other way to render volumetric fog in OpenGL?

One way I have thought of (I'm not a programmer, so this may sound stupid) is to have a function with three parameters f(x,y,z) that produces a cloud like pattern (f is the opacity of each coordinate) and make several slices, so that you have a few layers of two dimensional billboards laying upon each other, perpendicular to the point of view.

Nice link, thanks

You might like this one too: http://www.goat.com/universe.html. It's a whistle-stop tour of the Galaxy lasting 60 seconds, beautifully rendered, ending in Chicago (I think - my North American geography isn't very good).

Yes, very nice as well. Thank you Adam.
I just wish the movie were a bit more down-tempo...
