Unsafe version of: SnapshotMarkerDetectorML

xrSnapshotMarkerDetectorML

public static int xrSnapshotMarkerDetectorML(XrMarkerDetectorML markerDetector,
 XrMarkerDetectorSnapshotInfoML snapshotInfo)

Request a snapshot from the marker detector.

C Specification

The SnapshotMarkerDetectorML function is defined as:

 XrResult xrSnapshotMarkerDetectorML(
     XrMarkerDetectorML                          markerDetector,
     XrMarkerDetectorSnapshotInfoML*             snapshotInfo);

Description

Collects the latest marker detector state and makes it ready for inspection. This function only snapshots the non-pose state of markers. Once called, and if a new snapshot is not yet available a runtime must set the state of the marker detector to MARKER_DETECTOR_STATUS_PENDING_ML. If a new state is available the runtime must set the state to MARKER_DETECTOR_STATUS_READY_ML. If an error occurred the runtime must set the state to MARKER_DETECTOR_STATUS_ERROR_ML. The application may attempt the snapshot again.

Once the application has inspected the state it is interested in it can call this function again and the state is set to MARKER_DETECTOR_STATUS_PENDING_ML until a new state has been snapshotted. After each snapshot, only the currently detected markers are available for inspection, though the same marker may repeatedly be detected across snapshots.

Valid Usage (Implicit)

• The XR_ML_marker_understanding extension must be enabled prior to calling SnapshotMarkerDetectorML

nxrGetMarkerDetectorStateML

public static int nxrGetMarkerDetectorStateML(XrMarkerDetectorML markerDetector,
 long state)

Unsafe version of: GetMarkerDetectorStateML

xrGetMarkerDetectorStateML

public static int xrGetMarkerDetectorStateML(XrMarkerDetectorML markerDetector,
 XrMarkerDetectorStateML state)

Get the current state of the marker detector.

C Specification

The GetMarkerDetectorStateML function is defined as:

 XrResult xrGetMarkerDetectorStateML(
     XrMarkerDetectorML                          markerDetector,
     XrMarkerDetectorStateML*                    state);

Description

GetMarkerDetectorStateML is used after calling SnapshotMarkerDetectorML to check the current status of the snapshot in progress. When XrMarkerDetectorStateML::state == MARKER_DETECTOR_STATUS_READY_ML, the detector is ready to be queried, while MARKER_DETECTOR_STATUS_PENDING_ML indicates the snapshot is still in progress. MARKER_DETECTOR_STATUS_ERROR_ML indicates that the runtime has encountered an error getting a snapshot for the requested detector, which may require user intervention to solve.

 @Nullable LongBuffer markers)

Examine marker detection snapshot.

C Specification

The GetMarkersML function is defined as:

 XrResult xrGetMarkersML(
     XrMarkerDetectorML                          markerDetector,
     uint32_t                                    markerCapacityInput,

     XrMarkerML*                                 markers);

Description

Get the list of current snapshotted marker atoms, must only be called when the state of the detector is MARKER_DETECTOR_STATUS_READY_ML.

If GetMarkerDetectorStateML has not been called and returned MARKER_DETECTOR_STATUS_READY_ML since the last invocation of SnapshotMarkerDetectorML, the runtime must return ERROR_CALL_ORDER_INVALID.

The returned atoms are only valid while in the MARKER_DETECTOR_STATUS_READY_ML state. The runtime must return the same atom value for the same uniquely identifiable marker across successive snapshots. It is unspecified what happens if the detector is observing two markers with the same identification patterns.

Assuming the same set of markers are in view across several snapshots, the runtime should return the same set of atoms. An application can use the list of atoms as a simple test for if a particular marker has gone in or out of view.

Note that XrMarkerML atoms are only usable with the XrMarkerDetectorML that returned them.

This function follows the two-call idiom for filling the markers.

Valid Usage (Implicit)

• The XR_ML_marker_understanding extension must be enabled prior to calling GetMarkersML
• markerDetector must be a valid XrMarkerDetectorML handle
• markerCountOutput must be a pointer to a uint32_t value

     XrMarkerML                                  marker,
     float*                                      reprojectionErrorMeters);

Description

Get the reprojection error of a marker, only available for certain types of markers. must only be called when the state of the detector is MARKER_DETECTOR_STATUS_READY_ML.

If GetMarkerDetectorStateML has not been called and returned MARKER_DETECTOR_STATUS_READY_ML since the last invocation of SnapshotMarkerDetectorML, the runtime must return ERROR_CALL_ORDER_INVALID.

A high reprojection error means that the estimated pose of the marker does not match well with the 2D detection on the processed video frame and thus the pose may be inaccurate. The error is given in meters, representing the displacement between real marker and its estimated pose. This means this is a normalized number, independent of marker distance or length.

The runtime must return ERROR_MARKER_INVALID_ML if the marker atom is invalid.

Valid Usage (Implicit)

• The XR_ML_marker_understanding extension must be enabled prior to calling GetMarkerReprojectionErrorML

     const XrMarkerSpaceCreateInfoML*            createInfo,
     XrSpace*                                    space);

Description

Creates an XrSpace from a currently snapshotted marker. The space may still be used even if the marker is later not in the FOV, or even if the marker detector has been destroyed. In such a scenario, the SPACE_LOCATION_ORIENTATION_TRACKED_BIT and SPACE_LOCATION_POSITION_TRACKED_BIT must be false, but SPACE_LOCATION_POSITION_VALID_BIT and SPACE_LOCATION_ORIENTATION_VALID_BIT may be set as appropriate to the last known location.

Once an application has created a space, it may stop calling SnapshotMarkerDetectorML, and the position of the marker must still be updated by the runtime whenever it is aware of a more up to date location.

If a runtime is unable to spatially locate a snapshotted marker, it may return ERROR_MARKER_DETECTOR_LOCATE_FAILED_ML. This is most likely to happen if significant time has passed since the snapshot of markers was acquired, and the marker in question is no longer in the user’s FOV. Thus, an application should call CreateMarkerSpaceML immediately after examining a snapshot, but should also be prepared to try again if needed.

must only be called when the state of the detector is MARKER_DETECTOR_STATUS_READY_ML.

If GetMarkerDetectorStateML has not been called and returned MARKER_DETECTOR_STATUS_READY_ML since the last invocation of SnapshotMarkerDetectorML, the runtime must return ERROR_CALL_ORDER_INVALID.

session must be the same session that created the XrMarkerSpaceCreateInfoML::markerDetector, else the runtime must return ERROR_HANDLE_INVALID.

The runtime must return ERROR_MARKER_INVALID_ML if the marker atom is invalid.

The XrSpace origin must be located at the marker’s center. The X-Y plane of the XrSpace must be aligned with the plane of the marker with the positive Z axis coming out of the marker face.

Valid Usage (Implicit)

• The XR_ML_marker_understanding extension must be enabled prior to calling CreateMarkerSpaceML
• session must be a valid XrSession handle
• createInfo must be a pointer to a valid XrMarkerSpaceCreateInfoML structure
• space must be a pointer to an XrSpace handle
