[vtkusers] Multiple render windows on a single data set

[Eugene Kim]

Hi everyone,

 	I know this question has been asked and answered before, but the 
best answer I could find is that this is only possible at the level 
between dataset and mapper.  That is, for every new render window 
representing the data, we need a copy of the entire pipeline from the 
mapper up.
 	Now, we have discovered otherwise here.  We have been able to do 
this between the actor and the renderer.  That is, for every new render 
window we need seperate copies of the renderer and render window only. 
This is contradiction to what has been previously said.  I was wondering 
if I could get a more definitive answer from someone who might know more. 
I would ideally like to only have one copy of the data all the way up to 
the renderer, having only the render windows instantiated on their own. 
Anyone have any clues/answers?

Thanks,
Eugene Kim
