## Image Tracking
## Image Tracking — also available on the asset store [here](https://assetstore.unity.com/packages/templates/ar-foundation-demos-image-tracking-164880)
A sample app showing off how to use Image Tracking to track multiple unique images and spawn unique prefabs for each image.
The Prefabs for each number are prefab variants derived from [`OnePrefab.prefab`](https://github.com/Unity-Technologies/arfoundation-demos/blob/master/Assets/ImageTracking/Art/One/OnePrefab.prefab). They use a small quad that uses the [`MobileARShadow.shader`](https://github.com/Unity-Technologies/arfoundation-demos/blob/master/Assets/Common/Shaders/MobileARShadow.shader) in order to accurately show a shadow of the 3D number.
The script [`DistanceManager.cs`](https://github.com/Unity-Technologies/arfoundation-demos/blob/master/Assets/ImageTracking/Scripts/DistanceManager.cs) checks the distances between the tracked images and displays an additional 3D model between them when they reach a [certain proximity.](https://github.com/Unity-Technologies/arfoundation-demos/blob/master/Assets/ImageTracking/Scripts/DistanceManager.cs#L32)

## UX
### Missing Prefab in ImageTracking scene.
If you import the image tracking package or download it from the asset store **without** the Onboarding UX there will be a Missing Prefab in your scene. This prefab is a configured [ScreenSpaceUI prefab](https://github.com/Unity-Technologies/arfoundation-demos/blob/master/Assets/UX/Prefabs/ScreenspaceUI.prefab) from the Onboarding UX. It is configured with the UI for finding an image with the goal of finding an image.
