Detailed Description

Base class for all camera controllers, acting on a Camera node (abstract).

A typical CameraController offers actions for camera movement and rotation, and potentially for continuous flight of camera. It may further be possible to toggle between fly mode (free camera movement in space) and examine mode (camera movement relative to center point).
