Method Detail

onStateChanged

void onStateChanged(InstantTracker tracker,
                    InstantTrackingState state)

Will be called when the state of the tracker was changed internally. It is called after a call to InstantTracker.setState(com.wikitude.tracker.InstantTrackingState)

Parameters:

tracker - The tracker whose state was changed internally

state - The state to which the tracker changed

onStateChangeFailed

void onStateChangeFailed(InstantTracker tracker,
                         InstantTrackingState failedState,
                         WikitudeError error)

Will be called when changing the Instant Tracking state was not successful.

Parameters:

tracker - The tracker causing this error.

failedState - The state that was not able to be set.

onInitializationPoseChanged

void onInitializationPoseChanged(InstantTracker tracker,
                                 InitializationPose pose)

Called repeatedly during the initialization phase with information about the tracking plane

Parameters:

tracker - The instant tracker who is being initialized

pose - Information about the tracking plane

onTrackingStarted

void onTrackingStarted(InstantTracker tracker,
                       InstantTarget target)

Will be called when tracking is started. This is called first when switching from initialization phase to tracking phase, as well as later, when the tracking scene is recognized again after being lost.

Parameters:

tracker - The instant tracker that started tracking

onTracked

void onTracked(InstantTracker tracker,
               InstantTarget target)

Called repeatedly during the tracking phase.

Parameters:

tracker - The instant tracker that is tracking the scene

target - The tracked instant target that contains information about the scene

onTrackingStopped

void onTrackingStopped(InstantTracker tracker)

Will be called when tracking of the scene is lost

Parameters:

tracker - The instant tracker that lost tracking of the scene

onPlaneRecognized

void onPlaneRecognized(InstantTracker tracker,
                       Plane plane)

Called whenever an instant tracker recognized a new plane that was previously unknown.

Parameters:

tracker - The instant tracker that recognized the plane.

plane - The plane that was recognized.

onPlaneLost

void onPlaneLost(InstantTracker tracker,
                 Plane plane)

Called whenever a previously known plane is not found anymore.

Parameters:

tracker - The instant tracker that lost the plane.

plane - The plane that was lost.

onPlaneTracked

void onPlaneTracked(InstantTracker tracker,
                    Plane plane)

Called whenever a previously known plane was tracked again.

Parameters:

tracker - The instant tracker that tracked the plane.

plane - The plane that was tracked.
