General questions for a thesis work

I’m a student at “Università di Napoli Federico II”. I’m working on a thesis, regarding surgical simulation. I would be very grateful if you could give me some informations about PhysX.

Which kind of models for deformable object are available in PhysX? (Mass-Spring Model, Finite Elements, linear finite elements, co-rotational finite elements, non-linar finite elements, Boundary element or others)

What are the main PhysX applications? (videogame, animation, physical simulation, surgical simulation or others)

Does PhysX use any graphic libraires? If yes, which one?

I hope you can answer my questions. Thanks.

Kind regards.
