説明

Represents the tracking origin whereby 0,0,0 is on the "floor" or other surface determined by the XR Device being used. The pose values reported by an XR Device in this mode will include the height of the XR Device above this surface, removing the need to offset the position of the camera tracking the XR Device by the height of the user (VR) or the height of the device above the floor (AR).
