VROverlayError GetOverlayTransformAbsolute( VROverlayHandle_t ulOverlayHandle, TrackingUniverseOrigin *peTrackingOrigin, HmdMatrix34_t *pmatTrackingOriginToOverlayTransform )

Sets the overlay to use an absolute transform or gets the current absolute transform.

• VROverlayHandle_t ulOverlayHandle - Handle of the overlay to set/get absolute transform for
• TrackingUniverseOrigin eTrackingOrigin - Tracking origin to set transform relative to
• TrackingUniverseOrigin *peTrackingOrigin - Receives tracking origin that the transform is relative to
• HmdMatrix34_t *pmatTrackingOriginToOverlayTransform - Transform relative to the specified tracking origin

Description

Sets the overlay to use an absolute transform or gets the current absolute transform. Get will return an error if overlay transform is not VROverlayTransform_Absolute.
