Dear all,<br><br>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. <br><br>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?<br>
<br>Thank you very much for your help. I extremely appreciate it.<br><br>Best wishes<br>Long<br><br>
