Convert the signal from the servo by some means (you choose) into a
camera/actor position vector, or even a motion direction vector. Subclass
vtkInteractorStyle and drive your system directly - by forcing updates
within the interactor after each motion step. Alternatively, create a
camera object and do the same thing by forcing the renderwindow to render
after a certain time. Both options would allow you to either setup a timer
and automatically update or update when motion has occurred.
