Syntax

virtual void CalibrateExternalTrackingSource
(
    const FTransform & ExternalTrackingTransform
)

Remarks

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

Parameters

Description

ExternalTrackingTransform

(in) The transform in world-coordinates, of the reference marker of the external tracking system

Welcome to the new Unreal Engine 4 Documentation site!

We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.

We'll be sure to let you know when the new system is up and running.
