Camera ID - ID string of the tracker to be used for the camera tracking. The tracking systems can send data for multiple physical trackers at the same time and this ID can filter them. For stYpe, this should always be "0".

Protocol – The tracking system (protocol) to use.

Port – The UDP port on which to listen for tracking data. Required for stYpe, FreeD, EZtrack, LONET 2, not used for OptiTrack and Vicon.

FOV – Horizontal field of view override in degrees. This option is used to override the FOV value from the tracking system or the scene. By default, it's 0.0, which means that the override is disabled and the value from the tracking system or the scene is used. When disabled, the FOV is taken from the tracking system if it supports FOV tracking and currently provides a valid positive value or from the main camera exported in the scene.

Recording Directory – A directory for the recorded camera tracking Alembic files. By default, it's the Windows %TEMP% directory.

Sync Recording to Animation – When enabled, tracking samples are recorded only during the first animation playback with the exact animation times as rendered. This ensures that the exported Alembic file matches the scene animation when imported to the same scene. When disabled, all received samples are recorded with uniform time sampling based on the average FPS of the received data.

Unit Scale – Scaling factor for the position data received from the tracking system. Can be used for the correction of incorrectly calibrated tracking systems or scenes with a wrong scale. Normally it should not be needed.

1 button – Reset the scaling factor to 1.0.

Uniform Scaling – If enabled, the scaling is uniform on all dimensions; otherwise, it can be specified for each dimension separately.

Horizon Shift – Horizon shift effect for the camera inner frustum. Similar to a vertical lens shift effect.

Tracking Origin Offset 

...

Position and rotation offset of the tracking system relative to the current tracking origin in the configuration (the projection geometry or the tracking origin node if specified).

Тhis is the distance between the Camera Tracking System Origin (usually somewhere on the floor) on one hand and the Tracking Origin Node (if included in the .vrscene containing the geometry of the LED wall) or the pivot point of the wall geometry (if there is no Tracking Origin Node). If the Tracking Origin Node matches the actual tracking system origin perfectly, these offsets should be zero.

Camera Offset

...

Position and rotation offset of the camera's entrance pupil and orientation from the tracker's center point and orientation.

Тhis is the distance between the lens nodal point (usually inside the lens in front of the sensor) and the pivot point of the tracker which depends on the camera tracking solution (stYpe, Mo-Sys, Vicon, etc.)


Auto-Apply – If enabled, changes to the offsets, FOV, or camera ID are applied immediately during rendering without having to press the Apply Configuration button.

In the example below, using the Vive Mars tracking system, the center of the tracker occurs at the base of the Vive tracker, that is why the measurements start from there.

In the example below you can see how the Tracking Origin Offset is used.

The Tracking Origin offset is the distance between the Tracking Origin Node (if included in the .vrscene containing the geometry of the LED wall) and the Camera Tracking System Origin (usually somewhere on the floor). This example assumes that the tracking system's forward direction is pointing towards the screen.
