Detailed Description

Object Trackers are used to recognize and track objects defined in .wto files by using a TargetCollectionResource

When Object Trackers are created at runtime, make sure that all the relevant properties are set before the OnEnable method is called by Unity. At OnEnable, the native tracker is created and all information needs to be available.

Member Function Documentation

void Wikitude.ObjectTracker.StopExtendedTracking ( )

inline

Stops and immediately restarts extended tracking with a new tracking map. It is useful when tracking was lost and the user would like to return to the target to reinitialize extended tracking.

void Wikitude.ObjectTracker.UpdateAlignmentPose ( Matrix4x4  pose )

inline

Sends an update of the alignments pose to the SDK if alignment initialization has been chosen as the recognition type by setting ObjectTracker.UseAlignmentInitialization.

Parameters

pose	The pose of the alignment should contain its location, rotation and scale. The inputted scale should be set to 1 on all axes and the translation - or better said, the distance from the camera - should be adjusted for scaling purposes.

Member Data Documentation

OnExtendedTrackingQualityChangedEvent Wikitude.ObjectTracker.OnExtendedTrackingQualityChanged = new OnExtendedTrackingQualityChangedEvent()

Called whenever the quality of extended tracking changes. During a tracking session, the extended tracking quality might get better or worse, depending on the scene that is captured. This method is also called when extended tracking processed the first frame.

Property Documentation

TargetCollectionResource Wikitude.ObjectTracker.TargetCollectionResource

getset

The Target Collection Resource that will load the .wto file that contains the objects that should be tracked.

string Wikitude.ObjectTracker.TargetNameForAlignmentInitialization

getset

Defines the name for the target of the object tracker to be used for alignment initialization.

TrackerEfficiencyMode Wikitude.ObjectTracker.TrackerEfficiencyMode

getset

Defines the efficiency mode for the tracker. Has to be set before OnEnable is called, otherwise it will have no effect.

bool Wikitude.ObjectTracker.UseAlignmentInitialization

getset

Defines if alignment initialization should be used as the recognition type of the object tracker.
