This set of samples relies on five Unity packages:
* ARSubsystems
* ARCore XR Plugin
* ARKit XR Plugin
* ARKit Face Tracking
* ARFoundation
* ARSubsystems ([documentation](https://docs.unity3d.com/Packages/com.unity.xr.arsubsystems@3.0/manual/index.html))
* ARCore XR Plugin ([documentation](https://docs.unity3d.com/Packages/com.unity.xr.arcore@3.0/manual/index.html))
* ARKit XR Plugin ([documentation](https://docs.unity3d.com/Packages/com.unity.xr.arkit@3.0/manual/index.html))
* ARKit Face Tracking ([documentation](https://docs.unity3d.com/Packages/com.unity.xr.arkit-face-tracking@3.0/manual/index.html))
* ARFoundation ([documentation](https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@3.0/manual/index.html))
ARSubsystems defines an interface, and the platform-specific implementations are in the ARCore and ARKit packages. ARFoundation turns the AR data provided by ARSubsystems into Unity `GameObject` s and `MonoBehavour` s.
