Calibrate External Tracking to HMD |
Called to calibrate the offset transform between an external tracking source and the internal tracking source (e.g. mocap tracker to and HMD tracker). This should be called once per session, or when the physical relationship between the external tracker and internal tracker changes (e.g. it was bumped or reattached). After calibration, calling UpdateExternalTrackingPosition will try to correct the internal tracker to the calibrated offset to prevent drift between the two systems Target is Head Mounted Display Function Library |

Update External Tracking HMDPosition |
Called after calibration to attempt to pull the internal tracker (e.g. HMD tracking) in line with the external tracker (e.g. mocap tracker). This will set the internal tracker's base offset and rotation to match and realign the two systems. This can be called every tick, or whenever realignment is desired. Note that this may cause choppy movement if the two systems diverge relative to each other, or a big jump if called infrequently when there has been significant drift Target is Head Mounted Display Function Library |
