Animation Dashboard - Camera

Animation dashboard -> Camera tab
Lets you change your viewing or camera perspective. For example, you can change the perspective to always look at a particular part as it moves or to always look from a particular vantage point, such as one that moves with a part. Setting different camera perspectives is particularly helpful when parts undergo large motions and move off your screen during an animation, such as with vehicle simulations.
A good example of setting the camera perspective is when you simulate a vehicle driving through a slalom course on a test track. By default, you view the simulation as a bystander alongside of the road whose gaze is fixed in one direction. As the vehicle moves forward, it quickly moves out of your field of view. You can, however, set the camera perspective to mimic the movement of your head as it moves to follow the vehicle. Furthermore, rather than observe the vehicle as a bystander alongside a road, you can also set the camera perspective to mimic what the driver sees as he or she looks out the front windshield of the vehicle.
