Very impressive.. I know this is a bit of an old post, but would you mind
explaining a bit how the rendering was done? I have been looking at doing
realisting raytracing rendering on numerical simulations we run here...
We're able to do some volume rendering, but *nothing* that looks as good as
what one would get from a 'real' raytracer.

I am a POV-Ray newbie, however, so any pointers as to where to
look (i.e. data format, etc) would be MUCH appreciated.

Thanks, and congrats. Very good work.
