 This repository shares the assets I used in the Unity Project to build the app. They can be use for reference to build apps with a similar scope.
 
 
-1. **Scripts** stored the C# scripts for the app. The most important piece of code is _ImageTracking.cs_, which is added on top of the AR Tracked Image Manager API to allow it to track multiple images and spawn prefabs according to the filenames. _resets.cs_ reloads the AR session and scene, and is helpful for refreshing the tracking system.

+3. **Prefabs** stores the building model prefabs that will spawn on top of the building once they are detected. It also stores the _reference image library_ for the image tracking system.
+
+4. **Shaders** stores the shaders created for the grayscale filter visualiztion. _grabpass.shader_ is the grayscale filter used for the background and contexts. _StencilFilter.shader_ is for the buildings model to be left out of the grayscale filter rendering.
+
+5. **Materials** stores the materials that wrap the shaders mentioned above.
