[vtkusers] Get actors and volumes from vtkRenderer in Tcl

[Magnus Gedda]

Hi,

Is there a way to get information on which actors/volumes are added to a
vtkRenderer (using Tcl)?

I need to remove actors/volumes added to a vtkRenderer, but since I
don't keep track which actors/volumes I have added I cannot just use
"RemoveActor/RemoveVolume".

"GetActors/GetVolumes" looks like the way to go, but how do I extract
the actors/volumes from the returned collections?

This only seems to print the name of the returned collection (vtkTemp0).
$renderer is a vtkRenderer with some actors attached to it:
----------------------------------------
set renderActors [$renderer GetActors]

foreach actor $renderActors {
   puts $actor	
}

=> vtkTemp0
----------------------------------------
