Syntax

public class ARCoreFaceSubsystem : XRFaceSubsystem

Methods

CreateProvider()

Creates the ARCore-specific implementation which will service the XRFaceSubsystem.

Declaration

protected override XRFaceSubsystem.Provider CreateProvider()

Returns

Type	Description
XRFaceSubsystem.Provider	A new instance of the Provider specific to ARCore.

GetRegionPoses(TrackableId, Allocator, ref NativeArray<ARCoreFaceRegionData>)

Get all the available ARCoreFaceRegions.

Declaration

public void GetRegionPoses(TrackableId trackableId, Allocator allocator, ref NativeArray<ARCoreFaceRegionData> regions)

Parameters

Type	Name	Description
TrackableId	trackableId	The id associated with the face to query.
Allocator	allocator	The allocator to use if regions requires a resize. C# Jobs are used, so the allocator must be either Allocator.TempJob or Allocator.Persistent.
NativeArray<ARCoreFaceRegionData>	regions	An array of ARCoreFaceRegionDatas. If regions is allocated and the correct size, then its memory is reused. Otherwise, it is reallocated.

Exceptions

Type	Condition
InvalidOperationException	Thrown if allocator is Allocator.Temp.
InvalidOperationException	Thrown if allocator is Allocator.None.
