I came across this webpage 
http://www.cs.cornell.edu/~tedkim/WTURB/source.html the other day.

The authors of the paper are distributing their source code for free. I have 
downloaded the package since it purports to export to df3 format. I got it 
to compile using MSVC after adding zlib and libpng and making a few small 
changes to the png output in image.h. It runs fine but the output goes black 
(0 in the density files) after 3 or 4 frames. Nothing like the images on the 
website. I was hoping someone else would be interested in taking a crack at 
this and seeing if it works with a different compiler.

aanxious to get this to work...

Mike

Well, I finally gave in and installed cygwin and compiled the source using 
the included makefile and it works! I am at a loss for why the output is 
completely different using a build made with Visual Studio compared to one 
made with GCC. I looked through the code for hours and couldn't find 
anything that wasn't standard C++, at least as far as I could tell. I will 
post a test render once it finishes its run and can get the df3 files to 
work.
