# mouthFunnel

The coefficient describing contraction of both lips into an open shape.

## Declaration

```swift
static let mouthFunnel: ARFaceAnchor.BlendShapeLocation
```

## Discussion

Discussion 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.
