Mostly used for XR project, this camera simulate the optical distorsion of a real one.
By default, the physical camera is setted in Link To Tracker placement type.

Model and Resolution

The Model parameters defines the type of camera you simulate and how the radial distorsion will be calculated.
If the Tracker used to place this camera also sends optical information (focus, zoom, etc), those datas can be applied directly as the physical camera model using the "use tracker model" option.
Pick a model in the type list to access to its parameters. The types refers directly to the following Control Device tracking protocols (except for pinhole):

• Control Device
• OpenCVControlDevice
• Pinhole
• Stype Device
• TrackmenControlDevice

Change the resolution of the camera: If you want to change the resolution of the physical camera, you need to select in the first Stage Element group. That can be a Stage Elements Group or the Stage itself. Then in advanced parameter change the Default Camera Resolution to the wated value.

XR Calibrator

In case of XR project projects, you'll need to calibrate your setup. The physical camera is the only one that accept the XR Calibrator
to create a XR Calibrator, right click on the physical camera -> Tool -> Calibrator -> XR Calibrator
