•	AR-Powered Learning: Bring 3D models to life using Augmented Reality. Students can interact with these models in real-time, rotating and annotating them for better understanding.
•	Collaborative Learning Spaces: With unique room IDs, multiple students can join the same room, view the same 3D models, and engage in discussions or collaborative problem-solving.
•	Real-Time Chat: Chat with other room participants using an integrated chat feature powered by Firebase Firestore.
•	Intuitive Room Setup: Teachers or admins can easily set up rooms with custom 3D models and reference images, providing an easy-to-navigate interface for students.
•	Annotation Feature: Tap and hold on any 3D model to add annotations. This enables real-time feedback and collaboration on shared learning content.

	Admins, authors, or teachers can create a new room with a unique room ID and upload the necessary assets (3D models and reference images).
•	The assets are managed on the web portal and are stored on a file server with the corresponding room ID.
•	Admins can edit or delete the assets as required, and all files are ready for student use upon submission.

1.	Room Entry: Students enter the unique room ID provided by their teacher to access the associated learning materials.
2.	Download of Assets: The app automatically downloads the required assets (3D model, reference image) when a valid room ID is entered. These assets are cleared once the student exits the room.
3.	Interactive Room Home: After entering the room, students are taken to the room’s home screen, which includes options for:
•	Chatting with other room participants.
•	Accessing the AR scanner to scan reference images.
•	Viewing and interacting with the 3D model.
4.	Engaging 3D Visualization: Once a reference image is scanned, the associated 3D model is loaded, allowing students to view, rotate, and interact with it.
•	Annotation Feature: Students can tap and hold on specific areas of the 3D model to add annotations or comments, fostering collaborative learning.

•	iOS App: Built using Swift and UIKit, with ARKit integration for AR functionality.
•	Web App (Frontend): Built with React for a seamless and dynamic user experience.
•	Backend: Java-based backend to manage user authentication, room setups, and asset management.
•	Database: MySQL is used for storing user data, room details, and asset metadata.
•	Firebase Firestore: Real-time chat feature is powered by Firebase Firestore, enabling instant messaging between users in the same room.
•	NGROk: Used for API web hosting during the development phase.
