Syntax

public class XRFaceSubsystem : TrackingSubsystem<XRFace, XRFaceSubsystem, XRFaceSubsystemDescriptor, XRFaceSubsystem.Provider>, ISubsystem

Remarks

Use this class to access face tracking features in your app via accessing the generic API. You can also extend it to provide an implementation of a provider which provides the face tracking data to the higher-level code.

Constructors

Name	Description
XRFaceSubsystem()	Constructs a face subsystem. Do not invoked directly; call Create on the XRFaceSubsystemDescriptor instead.

Properties

Name	Description
currentMaximumFaceCount	Get the maximum number of faces the provider will simultaneously track.
requestedMaximumFaceCount	Get or set the maximum number of faces to track simultaneously.
supportedFaceCount	Get the number of faces the subsystem is able to track simultaneously in its current configuration.

Methods

Name	Description
GetChanges(Allocator)	Get the changes to faces (added, updated, and removed) since the last call to GetChanges(Allocator).
GetFaceMesh(TrackableId, Allocator, ref XRFaceMesh)	Get the mesh data associated with the face with faceId. The faceMesh is reused if it is the correct size; otherwise, it is disposed and reallocated using allocator.
