[vtkusers] Multiple Views with only one Rederer

[David Gobbi]

Hi Ruben,

As far as I know, there is nothing in VTK to automatically synchronize
renderers in the way that you are talking about.  You will need to
keep your own list of all the actors, and make sure that they are
added to all the renderers.  If you are just starting to write your
program now, this should be an easy thing to do, but if you already
have a program and are trying to "retrofit" it to show multiple views,
this could be a bit difficult.  Ditto for camera synchronization, you
will need to write your own code for doing this.

   David
