What programs are most successfull for visualization physical processess?
what kind of physical processes?
REALTIME or static images?
static images-> maple/matlab/mathematica should all suffice
realtime->mmm depends, you can use a game engine to try some simulations
but you'lll be looking for code in fortran or c/c++. Oh wait VTK or PTC are open source so you can try to learn them.VTK might be your best choice, unless your willing to learn a game engine.
Processes of deformations of falling objects into the black hole or olaso may be deformations in solid physics. Just thinking to compare deformation visualizations in Solid Physics and deformations near stong gravity sources.
