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

[vtk at scil.sinp.msu.ru]

Hi!
So, we have several actors added to the assembly.
(assembly->AddActor(actor1); etc)
We have renderer, and:
renderer->AddActor(assembly);

one actor became inactive (actor0, for example).
how can I delete it and render the scene without it?

Thanx!
