An augmented reality navigation app that helps students and visitors move around campus efficiently.
The system overlays **AR arrows** for turn-by-turn guidance and integrates a playful **Tap-to-Plant** function where users can place virtual plants along their route.
## Overview
Develop a WebAR application using **Three.js** that allows users to design their own urban planning scenarios directly in AR.
The system should provide a **library of 3D models (GLTF/GLB)** such as trees, benches, lamp posts, or small buildings.
Users can **select, place, and arrange models** in outdoor AR space through an interactive interface.
The app should also support **saving and retrieving scenes**, either locally (browser storage) or via a simple cloud service.
The focus is on creating a **working MVP in 2 days**: clear AR navigation + a small add-on for engagement.
**Goal**: Create a working **MVP in 2 days** with model placement, scene saving, and retrieval.

## Targets
-**AR arrows for navigation** between selected campus POIs (classrooms, labs, cafeteria, library).
-**Smooth transitions** between outdoor navigation (GPS) and indoor areas (simple building model).
-**Tap-to-Plant feature:** users can tap the ground to add a virtual plant/tree at a POI.
-**Info pop-ups (optional):** show POI name or basic info when approached.
## Targets
- WebAR interface with **model library** (GLTF assets for urban furniture, greenery, etc.)
-**Interactive placement**: users can tap to position, rotate, and scale objects
-**Scene management**: save and load scenes (local storage or cloud)
-**Simple UI** for browsing and selecting models
- (Optional) allow users to **share their designs** (export JSON or scene link)
