If you recorded data which represents some physical value in space (e.g. electron density) and you need to explore this dynamically in 3d (say you have a isosurface and you change the value it represents) what toolkit/program would you use?
Personally I used MayaVi and it has all the all the features I could need. Unfortunately it is sometimes unstable and often slow. So in principle I am looking for equally powerfull alternatives.
Edit: I know this should probably not be in the physics SE but I think the answer to my question could be relevant for many physicists.
