-osgVisual provides several approaches to control the camera (point of view). Independent from the selected driver the cluster modul transfer this camera position to all slaves, which modify their field of view according to the master view and their configured camera offset. All camera control mechanismd are implemented as camera manipulatord. This way it is easy to switch between them during runtime.

  * Auto homing camera position: Always returns to the standart viewpoint if the spacemouse is released. Spacemouse represents camera position.
- * Static camera position: The spacemouse input is added to camera position. The camera remains on the last position if the spacemouse is released.

 == Camera attached to object ==
 
 Another approach of camera control is the attachment to objects in the scene. Every object has a free configurable camera offset to specify offsets between object's and camera's position/attitude.
-This way the view out of an objects window (like the cockpit in a car or aircraft) can be represented. To move the camera view, the object hast to be repositioned, usually by connection the object to the externalLink.

 While the view out of the cockpit is the same like in other camera control methods, this way directly moves the objects to the right place, wich make's it easy to add a 3rd person viewer, collision detection etc. to the scene.
