Enum ARKitBlendShapeLocation

Enum values that identify the face action units affecting the expression on the face.

Namespace: UnityEngine.XR.ARKit

Assembly: Unity.XR.ARKit.FaceTracking.dll

Syntax

public enum ARKitBlendShapeLocation

Remarks

Each action unit corresponds to a facial feature that can move. A coefficient of zero for the feature represents the neutral position, while a coefficient of one represents the fully articulated position.

 Call <xref href="UnityEngine.XR.ARKit.ARKitFaceSubsystem.GetBlendShapeCoefficients(UnityEngine.XR.ARSubsystems.TrackableId%2cUnity.Collections.Allocator)" data-throw-if-not-resolved="false"></xref> to get the current coefficients of each
 blend shape location for the current facial expression.
