I don't know if I got what you mean, but you can use the standard VTK
interactor, if I understand right... see documentation for
vtkRenderWindowInteractor.
If you want to implement an user-defined interaction style, you can use the
vtkInteractorStyleUser and provide your user-defined functions to be called
whenever the user press a button or moves the trackball and so on...

(If you want, email me in private! I think we are working on the same
project...)
