Biometric City

Real-time 3D city visualization for NYC and Mumbai, overlaid with live biometric and urban data. Buildings pulse with activity. Data streams in over WebSockets. Built as an exploration of what it looks like when a city becomes observable.

A Three.js scene renders a procedurally structured city. A FastAPI backend pushes live data over WebSockets — biometric signals, urban activity metrics, crowd density approximations — and the city reacts in real time. District-level data updates animate across the skyline.

Two cities are modeled: New York and Mumbai. Blender scripts are included for the 3D asset generation so the scenes can be extended or rebuilt.
