[vtkusers] when the actorCollection is filled up?!

[Giancarlo Amati]

Hello everybody,

I have this piece of  code:


    this->_ren->AddActor(imgAct1);
    this->_ren->AddActor(imgAct2);
    this->_ren->AddActor(imgAct3);

    _ren->Render();
    _ren->ResetCamera();

where imgAct# are objects of vtkImageActor. Now,

Just after these statements, I call _ren->GetActors() to retrieve the actorCollection but it returns an empty collection.......why?

Kind regards.
Giancarlo
