[vtkusers] multiple actor/renderer pairs connectable to single mapper?

[Roland Schwarz]

I am plannig to use MFC with VTK, and I am wondering whether it is *correct*
to have multiple actors that belong to different renderwindows  added to a
single mapper.

As I digged into the mail archive I found a somewhat dated statement:

Is this still true, or have things changed in vtk 4.0 times?

If I need to have mapper/actor/renderwindow aggregates may I connect
multiple mappers to a single dataset?

So much questions....

hopefully someone can give me a hint.

Thank you,
