Does VTK support modifying VTK pipelines in real-time?

Say I have a source S, I add a filter F1, I add mapper M and an actor A. Finally I add A to a renderer linked to a window.

Can I add a filter F2 on/in demand/real-time between F1 and M: does VTK supports this kind of things?

Yes, you can change properties of filters and connections between filters anytime as long as you execute and modify them on the same thread.
