AR Architecture Walkthrough for Building Plans – IT & Computer Engineering Guide
1. Project Overview
The AR Architecture Walkthrough for Building Plans is an augmented reality application designed to visualize 3D architectural models in real-world environments. The solution allows architects, clients, and engineers to walk through a virtual structure on-site using mobile or tablet devices, enabling better spatial understanding, design communication, and revision planning.
2. System Architecture Overview
- AR Visualization Engine: Renders 3D architectural models
over real surfaces
- Model Converter: Translates CAD/BIM files into optimized AR-compatible
formats
- User Interaction Module: Navigation, view controls, layer toggles
- Cloud Backend: Hosts 3D assets, session data, annotations
- Collaboration Module: Real-time shared walkthroughs
