C Specification
The xrSetMarkerTrackingTimeoutVARJO function is defined as:
// Provided by XR_VARJO_marker_tracking
XrResult xrSetMarkerTrackingTimeoutVARJO(
XrSession session,
uint64_t markerId,
XrDuration timeout);
Parameters
Description
The xrSetMarkerTrackingTimeoutVARJO function sets a desired lifetime
duration for a specified marker.
The default value is XR_NO_DURATION.
Negative value will be clamped to XR_NO_DURATION.
It defines the time period during which the runtime must keep returning
poses of previously tracked markers.
The tracking may be lost if the marker went outside of the trackable field
of view.
In this case the runtime still will try to predict marker’s pose for the
timeout period.
The runtime must return XR_ERROR_MARKER_ID_INVALID_VARJO
if the
supplied markerId
is invalid.
