Project description:
"Client App - Full Development Brief
Overview:

This is the official feature specification for the Client App of the 3D Shopping AI project.
The app will allow users to enter a virtual 3D city (already designed in Blender), interact socially, shop, communicate, and manage their orders — all using a mixed system of AR, 3D models, and real-time features.
• The virtual city is already modeled using Blender.
• The city will be integrated with Unreal Engine for navigation, interactions, and avatar control.
• Once integrated, Unreal Engine will be connected to the client mobile app via Unity/Flutter bridges and APIs.
