I have a perspective camera that moves around looking for objects. I would like to be able to rotate the camera maintaining the same angle down. Just like a person turning in a circle looking down.
I cannot rotate on Y since Y is not up because of the tilt. Rotation on the true up is needed.
LookAt(TransForm) will not work because the camera is not looking at anything.
Maybe I could have a point travel around the camera and have LookAt(Vector3)follow it.
