# geometry

A coarse triangle mesh representing the topology of the detected face.

## Declaration

```swift
var geometry: ARFaceGeometry { get }
```

## Discussion

Discussion This mesh provides vertex, index, and texture coordinate buffers describing the 3D shape of the face, conforming a generic face model to match the dimensions, shape, and current expression of the detected face. You can visualize the face geometry by passing these buffers to your preferred rendering engine. To visualize a face geometry using SceneKit, create an ARSCNFaceGeometry instance and use its update(from:) method to update it to match the face geometry.
