[vtkusers] Please help me to reset the camera. (reset the rotation)

[Cory Quammen]

If you want to reset your camera to an initial state (or view, however you
want to look at it), why not just save the camera state and restore it when
you reset the camera? You can use vtkCamera.GetPosition(), GetFocalPoint(),
and GetViewUp() to get the basic camera state and there are corresponding
methods SetPosition(), SetFocalPoint(), and SetViewUp() that you can use to
restore the camera state.

Hope that helps,
Cory
