AR face manager
The face manager is a type of trackable manager.
The face manager creates
GameObjects for each face detected in the environment. The system only detects human faces.
In some implementations, face tracking requires a different camera (for example, front-facing vs rear-facing) and might be incompatible with other features, such as plane or image tracking. Consider disabling other AR managers which manage trackables. These include:
Responding to faces
Faces can be added, updated, and removed. Once per frame, if the application detects a face, the AR face manager invokes the
facesChanged event. This events contains three
Lists of faces that have been added, updated, and removed since the last frame.
When a face is detected, the AR face manager instantiates the Face Prefab to represent the face. The Face Prefab can be left
null, but the face manager ensures the instantiated
GameObject has an
ARFace component on it. The
ARFace component only contains data about the detected face.
The face provider might provide a mesh that represents the face. The
ARFace component exposes
uvs (texture coordinates). Some or all of these can be available.
ARFaceMeshVisualizer component generates a
UnityEngine.Mesh and updates the
MeshFilter on the same
GameObject based on the data that the
