[vtkusers] AddActor - Help

[Nasos Iliopoulos]

Calude, 
if you change the properties of any actor that has been added to the renderer, those changes will appear in the next render call. 

i.e:
disk->SetScale(2.0);
 ren->GetRenderWindow()->Render();
Also keep in mind that it is better to have a mechanism to keep a pointer to your actor, so that you can modify it outside the function it was created. 

Can you also please clarify:when you say you modify the disk, this means you modify the actor, or your source or maybe filter?
