## Overview

This Unity project demonstrates Quest passthrough-camera marker tracking: the user opens a sample scene, camera imagery is obtained, and OpenCV-based ArUco or ChArUco tracking supports an AR result. The README documents the scenes, modes, dependency, and configurable marker-to-GameObject pairs, but no source excerpts were provided; internal call order and the camera-adjustment script’s role therefore remain unspecified.

Main entry points: [`QuestMarkerTracking/Assets/Scripts/ChArUcoMarkerTracking.cs`](https://github.com/takashiyoshinaga/questarucomarkertracking/blob/main/QuestMarkerTracking/Assets/Scripts/ChArUcoMarkerTracking.cs) (ChArUco tracker), [`QuestMarkerTracking/Assets/1 - ArUcoMarkerTracking.unity`](https://github.com/takashiyoshinaga/questarucomarkertracking/blob/main/QuestMarkerTracking/Assets/1%20-%20ArUcoMarkerTracking.unity) (ArUco sample scene), [`QuestMarkerTracking/Assets/Scripts/ArUcoTrackingAppCoordinator.cs`](https://github.com/takashiyoshinaga/questarucomarkertracking/blob/main/QuestMarkerTracking/Assets/Scripts/ArUcoTrackingAppCoordinator.cs) (ArUco coordinator), [`QuestMarkerTracking/Assets/Scripts/ArUcoMarkerTracking.cs`](https://github.com/takashiyoshinaga/questarucomarkertracking/blob/main/QuestMarkerTracking/Assets/Scripts/ArUcoMarkerTracking.cs) (ArUco tracker)
