[vtkusers] Multiple actors using discretemarchingcubes

[Thommen Korah]

I am able to use vtkDiscreteMarchingCubes to generate differently colored and labeled volumes. At the end of the visualization pipeline, I get a single vtkActor representing each labeled volume. How can I get separate vtkActors for each component.
I understand that I can call discrete marching cubes on each label separately and store the resulting actor. I was wondering if there was a more correct way to extract the actors separately.
Thanks.
