OpenDX www.opendx.org My choice... You don't have to limit what you visualize
with it. This thing is just plain amazing. Matlab {amongst others {Scilab} can
do file conversions for you {take a look at h5 for conversions... maybe Cactus
if you really decide to get into it...}
Mayavi {If you're into Python...}
Grass {I've not used it in years... It was excellent in the late '9os though
and it looks like it's gotten "popular".}
{maybe vxl... It's a language for "computer vision" ....I'm just setting it
up. I'm not quite sure what functionality it might add to your system {s}.
...It looks as though it's got potential though. There *is* a lot of stuff
here: http://www-2.cs.cmu.edu/afs/cs/project/cil/ftp/html/vision.html {One of
my favorite web pages. :}} Don't blame me if you download it and it's useless.
It *seems* really similar to:
VTK/ITK
http://public.kitware.com/VTK/
http://www.kitware.com/case/vtkinuse.html
{Do take a look at what they're doing with some of their projects.}
Oh... thanks for the hint about the above... I was at the page the other
night and decided I didn't have time to mess with it... after reading a bit
more it looks as though it could be excellent though....
