Global Variable

ARBlendShapeLocationMouthClose

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

Declaration

const ARBlendShapeLocation ARBlendShapeLocationMouthClose;

Discussion

This coefficient describes a closing of the lips without relation to the position of the jaw (the ARBlendShapeLocationJawOpen coefficient), so some values of the ARBlendShapeLocationMouthClose 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 ARBlendShapeLocation coefficient values at 0.0, including both ARBlendShapeLocationJawOpen and ARBlendShapeLocationMouthClose)

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

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