Hi all, I came across the work of Bin Nguyen from Rensselaer Polytechnic Institute, that has worked on the development of a physics simulator nicknamed dVC3d. He integrated this simulator within Blender : very nice videos can be seen at http://cgi2.cs.rpi.edu/~nguyeb2/doku.php?id=dvc3d Cheers, Simon Lacroix (LAAS)
