Namespace: UnityEngine.XR.ARFoundation
Syntax
public sealed class ARFace : ARTrackable<XRFace, ARFace>
Remarks

Generated by the ARFaceManager when an AR device detects a face in the environment.

Properties

indices

The indices defining the triangles of the face mesh. Check for existence with indices.IsCreated. The are three times as many indices as triangles, so this will always be a multiple of 3.

Declaration
public NativeArray<int> indices { get; }
Property Value
Type Description
NativeArray<Int32>

normals

The normals representing the face mesh. Check for existence with normals.IsCreated. This array is parallel to vertices and uvs.

Declaration
public NativeArray<Vector3> normals { get; }
Property Value
Type Description
NativeArray<Vector3>

uvs

The texture coordinates representing the face mesh. Check for existence with uvs.IsCreated. This array is parallel to vertices and normals.

Declaration
public NativeArray<Vector2> uvs { get; }
Property Value
Type Description
NativeArray<Vector2>

vertices

The vertices representing the face mesh. Check for existence with vertices.IsCreated. This array is parallel to normals and uvs. Vertices are provided in face space, that is, relative to this ARFace's local position and rotation.

Declaration
public NativeArray<Vector3> vertices { get; }
Property Value
Type Description
NativeArray<Vector3>

Events

updated

Invoked when the face is updated. If face meshes are supported, there will be updated vertices, normals, indices, and uvs.

Declaration
public event Action<ARFaceUpdatedEventArgs> updated
Event Type
Type Description
Action<ARFaceUpdatedEventArgs>
