I really want to know what their using for the FX; Houdini's particles? Something else? Something totally new?
I read on CG Society I think that they actually did write new physical simulation software to give the Enterprise and other debris a more realistic feel.
EDIT: Yep, here it is:http://www.cgsociety.org/index.php/CGSF ... /star_trek
ILM developed a special tool called "Fracture."
I bet you can't guess what it does.
