WTTrackingMapRecorderDelegate Protocol Reference

Conforms to	NSObject
Declared in	WTTrackingMapRecorder.h

Overview

@Brief WTTrackingMapRecorderDelegate provides methods that inform about an active 3d tracking map recording session.

`– trackingMapRecorder:didChangeTrackingMapRecordingQualityFrom:toQuality:`

@Brief Called whenever an active 3d tracking map recording session changes it’s quality.

- (void)trackingMapRecorder:(WTTrackingMapRecorder *)trackingMapRecorder didChangeTrackingMapRecordingQualityFrom:(WTTrackingMapRecordingQuality)oldTrackingQuality toQuality:(WTTrackingMapRecordingQuality)newTrackingQuality

Parameters

`trackingMapRecorder`	The WTTrackingMapRecorder object that changed it’s traching quality
`oldTrackingQuality`	The previously tracking quality before the new value was registered internally
`newTrackingQuality`	The new tracking quality

Discussion

The new recording quality might be worse than the previous one, meaning that a new value doesn’t has to be better than a previous one.

`– trackingMapRecorder:didUpdateTrackingMapRecordingState:`

@Brief Called whenever the state of a active recording session changes.

- (void)trackingMapRecorder:(WTTrackingMapRecorder *)trackingMapRecorder didUpdateTrackingMapRecordingState:(BOOL)isRecording

Parameters

`trackingMapRecorder`	The WTTrackingMapRecorder object that changed it’s recording state
`isRecording`	Indicates if the recording is running or not

Discussion

This method can be used to detect interruptions (tracking got lost) during a recording sessions. Once the recording was interrupted, -isRecording will return NO and -stopTrackingMapRecording/-startTrackingMapRecording has to be called in order to start a new tracking map recording session.

`– trackingMapRecorder:didUpdateTrackingMapRecording:`

@Brief Called whenever an active 3d tracking map recording session changed it’s tracking information.

- (void)trackingMapRecorder:(WTTrackingMapRecorder *)trackingMapRecorder didUpdateTrackingMapRecording:(WTTarget *)trackingMap

Parameters

`trackingMapRecorder`	The WTTrackingMapRecorder object that updated it’s recording data
`trackingMap`	An object that represents the current recording state. This can be used to already draw augmentations while the recording is running.

Discussion

The new tracking map recording information can be used to already place objects in 3D space to e.g. visualize the recording process.
