I’m trying to develop a function that can pan the actor in the render window without changing its coordinates(I can not use the transform filter), just like drag the object in the window using your mouse. So I think maybe change the position of the camera is the solution? After some research, I figure out I need to change the position and focal points of the camera, which is not straightforward in my opinion. I’m wondering if there is other way to do it? Thank you very much for your help!
