Hi all, Matt asked me to share some recent volume renderings that I've made, along with the scripts to go with them. I've posted one such example here: http://casa.colorado.edu/~skillman/research_and_codes/files/0c4c670cea1660ae... Beware the movie is about 260 MB. This is a fairly small simulation but is a good example of what the volume renderer can do. I've implemented an "embarrassingly" parallel script that allocates one datadump/viewpoint to each processor. Here each of the 1717 frames can be partitioned and rendered in about a minute for a 1024^2 image, meaning that on 16 processors this took about 2 hours. If you have questions about how the script works, please let me know. Cheers, Sam -- Samuel W.

Wow, awesome work, both of you! I enjoyed your other renderings on your website, too. And thanks for sharing your parallel script! I looked through the ray tracing code, and saw that it could only supports one field. Would it be easy to support separate fields for opacity and color? i.e. density for opacity and temperature for color. Then we can re-create those "photo-realistic" renderings ... http://www.astro.princeton.edu/~jwise/movies/FirstStarLighting_CLASSIC_HD_MO... http://www.astro.princeton.edu/~jwise/movies/FirstStarLighting_RedBlue_MONO_... with yt!

Hi John,
Thanks for your kind words -- and as for the rho & T, it's
*definitely* possible. I'd put work on the backend on hold for a
while, but this has always been in my head -- I think it's very
important to have multi-variate transfer functions. Actually, if you
have a multiple variable transfer function in mind you could hand off
to me, I'd be eager to give a go at extending the machinery to support
multiple variables!
As a side note, those movies are absolutely gorgeous. I'm honored to
even hear you broach the subject.

Hi Matt, Great news. I can cook up a multi-variable transfer function over the weekend and send it over. Anyways I'm trapped in with the 2 feet of snow falling tonight and tomorrow! John On 5 Feb 2010, at 20:02, Matthew Turk wrote:

Nice looking movies, are we looking at star forming or blowing up?:-) Been using VisIt to do rendering, need to learn a new toy to play with now heh From G.S.

Thanks. The "RedBlue" movie shows the radiative feedback during the main sequence, and then the ensuing supernova. I've used VisIt before for multi-variable volume renderings but was never happy with the results. But seeing the quality (i.e. sharpness) of the density volume renderings makes yt a good candidate on reproducing these renderings. John On 5 Feb 2010, at 21:25, gso@physics.ucsd.edu wrote:
