The Hunt for Red Octangles is a 3D blimp-reconnaissance game using Three.js that turns real-world locations into 'Grid' type maps from the movie Tron. You can jump to almost any city in the world (Manhattan, Paris, London, or even your own neighborhood) and the game will procedurally generate the 3D buildings and road networks using the Overpass API.

The Tech Stack:

Three.js: For the 3D rendering and searchlight effects.

Overpass API (OSM): For fetching building footprints and road vectors.

Photon API (Komoot): For the geocoding/search functionality.

Drone view is so high it's unusable. How about an inside-the-blimp view?

Rural areas are trivially easy. May not be anything to do about that.

how about labelling famous locations like Times Square or the Louvre?

Anomaly is misspelt on home page.

Is it possible to make a version with a simplified geonetry? My computer gets too slow rendering the city.

The geometry is already simplified. It is possible to make a version with rendering that runs at reasonable speed, though.

Congrats on your release! That said, please stop posting AI slop to Hacker News.
