Oh, I see - to be able to define various stationary camera-views of a scene.
I could see how that would be useful - might save a little time since setting a camera graphically is somewhat easier than doing it programatically.
I was thinking, without a 3DS camera loader, you could do something similar by placing a seperate object into the 3DS model in the position and orientation that you would like the camera to be. It could consist of a right-triangle with three vertices ("position", "up", and "look"). Using the vertice positions you could define a camera position, look-direction, and up-direction, and use the Camera.setOrientation() method to move the camera to that view.
