[vtkusers] Animation in an interactive window

[Vardhman Jain]

Hi,
   I am trying to write a program which requires some kind of
animation of the actors, for which I am currently using a simple for
loop. I was to enable some mouse/keyboard interaction to be able to
the camera, AFAIK I have to do

  vtkRenderWindowInteractor *iren = vtkRenderWindowInteractor::New();
  iren->SetRenderWindow(renWin);
 and then iren->Start();

How do I mix the for loop and this function call together? In
OpenGL/Glut I would have used a glutTImer to get the animation and
glutKeyboardFunc to do the interaction, can some one suggest how to
achieve this in VTK.

Thanks in anticipation.
