[Imstk-developers] Copying Vega data

[Sreekanth Arikatla]

Hi Nick,
            Yes, that can be done (I was under the impression that even
that operation was slow with vtk but haven't looked into that part myself).
The copy could additionally be made conditional since rendering typically
runs faster than the physics.

The mesh needs to be updated though (at least in the case where visual and
physics are the same) since the physics update of future time steps count
on it.
