[vtkusers] How to display each actor in the real-time?

[ye.yuanzhi]

hi,all:
    I have a object  is made up of some surfaces  of some unstructured planes. I want to control each part to display in real time. How to control it? I used the AddActor and
the RemoveActor in my project,but if the actor was been added , the RemoveActor don't have any effect.Help me, thanks in advance!
    				if(this->m_bDem == true)
					this->ren1->AddActor(this->m_nTINActor[i]);//
				else
					this->ren1->RemoveActor(this->m_nTINActor[i]);
