In a completely unrelated search on google, I stumbled upon this site
http://www.csit.fsu.edu/~beason/
Since I’m leaving for the movies in 10 mins I really can’t say more about it, other than - check out the gallery! :ba:
Also, I saw that the sourcecode is available, but I didn’t see under which license.
Anyway, have fun looking at his site, I know I will once I get home again 
wow that looks nice. How easy would this be to use?
Not at all, Pane has been out for a while now (like two years). Its source code is avalible for those who can program, but the render times are harsh and the code complex, anyone up for the challenge is welcomed to try and port it.
I’m most impressed with his smoke/fluid simulations. Check out the videos of volumetric smoke he created with his software!
If that could be integrated into Blender, I think I’d die from elation! :o
We should recruit that guy to code for Blender development.
He has some pretty neat stuff.
if this guy has released in open source pane,maybe he would developp integratet their project if someone write him to ask.
the smoke looks very promising.
Oh god! I would die if Ton recruited this guy for blender!
Hey everyone he’s out for hire, he’s got his resume up on there!
Somebody should give Ton a ring to check this guy out.
though Im sure he could help with Blender’s rendering engine, Blender isnt a raytracer like Pane, Yafray, Povray etc - and its designed to be fast.
As an example, it may not be workable to include features from pane, into blenders internal rendering engine even if one wanted to. - pane features would better be ported to yafray or another raytracer.
Im not sure how intergrated blenders built in raytracer can be, f00f was working on GI for blenders rendering engine a while ago and had some nice renders so maybe Im wrong.
Is this open source? wow!
Check the fluids simulation: http://www.csit.fsu.edu/~beason/fluid/
Werry impressive. If this is opensource, will can be added into Blender? Will be great! The 3D fluids for smoke and fire and the 2D part for Compositor.
Gosh, I guess then Ton would be held liable for manslaughter. 
He does look like a talented programmer though.
this guy is open source fan,maybe if someone ask him he could help.
i think this mail is in this website.
