Declaration
static let mouthRollLower: ARFaceAnchor.BlendShapeLocationDiscussion
The figure below shows a face geometry (see ARSCNFaceGeometry) in two states, demonstrating values of 0.0 and 1.0 for this coefficient. In both states, the values for all other ARFaceAnchor.BlendShapeLocation coefficients are set to 0.0.
