It is possible to specify the distance between camera and object, and the number of revolutions around the object during the simulation. With "orientation" the camera's rotation can be clockwise or counter-clockwise.
The script is for Y-based axis setups. If you have a Z-based axis setup go to → "Camera Operations (Z-Setup)"
