Hi,all:

I have four actors(such as vtkActor *m_Actor[4]),they do same rotate.If I should do this.I must write following code:

m_Actor[0]->RotateZ(30);

m_Actor[1]->RotateZ(30);

m_Actor[2]->RotateZ(30);

m_Actor[3]->RotateZ(30);

So,I want add those up to one actor(such as m_ActorNum) that I only to do:

m_ActorNum->RotateZ(30) and can rotate all of m_Actor[4].

Could you tell me how to do so?

thanks a lot!
