[vtkusers] Aim Camera to Actor

[Wenlong Wang]

Dear all,

I'm trying to aim my camera to my acotr. By aim, I mean remain camera focal
distance the same, and set the focal point to the centre of the actor.

I know there are ways like manipulating vtkCamera::SetDistance and
vtkCamera::SetFocalPoint, but, is there any other automatical way to do
that? Such as I set an actor as input parameter and then the camera keep
tracking and focus on this actor?

Thank you very much for your help. I extremely appreciate it.

Best wishes
Long
