mouthClose

The coefficient describing closure of the lips independent of jaw position.

Declaration

static let mouthClose: ARFaceAnchor.BlendShapeLocation

Discussion

This coefficient describes a closing of the lips without relation to the position of the jaw (the jawOpen coefficient), so some values of the mouthClose coefficient can produce unrealistic facial expressions unless other coefficients are also set to realistic values.

The figure below shows a face geometry (see ARSCNFaceGeometry) in three states:

  1. A neutral face (all ARFaceAnchor.BlendShapeLocation coefficient values at 0.0, including both jawOpen and mouthClose)

  2. Setting only the jawOpen coefficient to 1.0, while keeping all other coefficient values (including mouthClose) at 0.0

  3. Setting both the jawOpen and mouthClose coefficients to 1.0, while keeping all other coefficient values at 0.0
