Camera rotation - which way is easiest?

[Zlobnyi Serg]

I need to rotate camera around some point (camera.lookAt(somepoint)) in worldspace. Is there embedded routines to implement this action, or which way is easiest to rotate camera around?

Thank you!

One way is to place the camera at "somepoint", do the rotation and move the camera backwards. Something like

Code Select Expand

camera.setPosition(somepoint);
camera.rotateCameraY(0.1f);
camera.moveCamera(Camera.CAMERA_MOVEOUT, 20f);
camera.lookAt(somepoint); //Maybe not needed in this case...depends on the application

Another solution would be to create a dummy object that rotates around "somepoint" and set the camera to its position every frame. In this case, the lookAt() is definitely needed.
