[vtkusers] Updating a scene

[Luke J West]

Hi,

when I call actor->SetPosition(x) followed by ren->Render();

The changes are not reflected in the window. I.e. the actor's position has not
chaned in the window. Do I need to call some kind of Update method to reflect
the changes, and of so - on which object.

thanks,
