If your image in place at the world origin, vtkCamera::SetPosition will only change the camera position, but the camera focal point
will stay on the world origin. Use vtkCamera::SetFocalPoint to move the destination seen by the camera.

  Hello vtk user,

  I can't move a camera on a renderer :
  I have an imageActor in my renderer. I can zoom in and out it but the zoom is based on the image center so i can't see image corners.
  I would like to move the camera thanks interaction not to see only the image center. I tried vtkCamera::SetPosition and i refresh the renderWindow but nothing happened.
  Somebody could help me ??

  Thank's
  Ludo
