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.
## ImageTracking
This sample demonstrates image tracking. Image tracking is supported on ARCore and ARKit. To enable image tracking, you must first create an `XRReferenceImageLibrary`. This is the set of images to look for in the environment. [Click here](https://docs.unity3d.com/Packages/com.unity.xr.arsubsystems@3.0/manual/image-tracking.html) for instructions on creating one.

At runtime, ARFoundation will generate an `ARTrackedImage` for each detected reference image. This sample uses the [`TrackedImageInfoManager.cs`](https://github.com/Unity-Technologies/arfoundation-samples/blob/master/Assets/Scenes/ImageTracking/TrackedImageInfoManager.cs) script to overlay the original image on top of the detected image, along with some meta data.
Similar to the image tracking sample, this sample detects a 3D object from a set of reference objects in an `XRReferenceObjectLibrary`. [Click here](https://docs.unity3d.com/Packages/com.unity.xr.arsubsystems@3.0/manual/object-tracking.html) for instructions on creating one.

To use this sample, you must have a physical object the device can recognize. The sample's reference object library is built using two reference objects. The sample includes [printable templates](https://github.com/Unity-Technologies/arfoundation-samples/tree/master/Assets/Scenes/Object%20Tracking/Printable%20Templates) which can be printed on 8.5x11 inch paper and folded into a cube and cylinder.
