MEDINA URBAN INNOVATION LAB

A city you can explore.

A Three.js proof of concept with procedurally modelled Medina-inspired architecture, physical-scale roads, detailed utility infrastructure and interactive IoT devices.

This is an illustrative district, not a surveyed replica of Medina. All readings, traffic and incidents are simulated in your browser. No live devices, K3s cluster or private city data are connected.

City view: select a sensor or building to inspect it.
City builder: place buildings and devices on open ground.
Control centre: run scenarios and inspect network events.
Adjust time of day, explore utilities, or follow the coverage layer.

New campuses and drone missions are illustrative designs. Architecture references: Medina courtyard shading by SL Rasch. Three.js r170, MIT licence. Geometry, textures and telemetry fixtures created for this PoC.
