[vtkusers] assembly, actors, add/remove and rendering

[Andres Barrera]

Hi,

    Try    "( (vtkActor*) 
renderer->GetActors()->GetItemAsObject(actorNumber) )->VisibilityOff() ;"

    i.e.
        assembly->AddPart( ball    );
        assembly->AddPart( cube );
        assembly->AddPart( cone );

        renderer->AddActor( actor1);      // 0
        renderer->AddActor( actor2);      // 1
        renderer->AddActor( assembly);  // 2-4
        renderer->AddActor( actor3);     // 5

    then
           ( (vtkActor*) renderer->GetActors()->GetItemAsObject( 3 ) 
)->VisibilityOff() ;

          will hide "cube"
