Syntax

public class XRImageTrackingSubsystem : TrackingSubsystem<XRTrackedImage, XRImageTrackingSubsystem, XRImageTrackingSubsystemDescriptor, XRImageTrackingSubsystem.Provider>, ISubsystem

Constructors

Name	Description
XRImageTrackingSubsystem()	Constructs a subsystem. Do not invoke directly; call Create on the XRImageTrackingSubsystemDescriptor instead.

Properties

Name	Description
currentMaxNumberOfMovingImages	The current maximum number of moving images to track. This can be different from requestedMaxNumberOfMovingImages.
imageLibrary	Get or set the reference image library. This is the set of images to look for in the environment.
requestedMaxNumberOfMovingImages	The requested maximum number of moving images to track.

Methods

Name	Description
CreateRuntimeLibrary(XRReferenceImageLibrary)	Creates a RuntimeReferenceImageLibrary from an existing XRReferenceImageLibrary, or an empty library if serializedLibrary is null. Use this to construct the runtime representation of an XRReferenceImageLibrary.
GetChanges(Allocator)	Retrieve the changes in the state of tracked images (added, updated, and removed) since the last call to GetChanges.
OnStart()	Starts the subsystem, that is, starts detecting images in the scene. imageLibrary must not be null.
OnStop()	Stops the subsystem, that is, stops detecting and tracking images.
