Hello Totte,

Interactors are now changed by setting the interactor style of a render
window interactor.  One of the interactors styles is a trackball
(vtkInteractorStyleTrackball) and it has the method you want.


Something like this will do it:
vtkInteractorStyleTrackball *tball = vtkInteractorStyleTrackball::New();
tball->SetTrackballModeToTrackball();
RenderWindow->GetInteractor()->SetInteractorStyle(tball);

Good luck,
Hank Childs
