# Camera2D

Camera2D is the physical orthonormal coordinate system for a single camera. There is one instance of such a coordinate system for each camera. The origin of Camera2D is at a position in Home2D that corresponds to the center of the camera's image window. Its X axis is parallel to and points in the same direction as the Raw2D X axis. Its Y axis is perpendicular to the X axis and points in the general direction of the Raw2D Y axis.
