  1. 1.in brief

    a live 3D model of a city district

  2. 2.in general

    A city block that keeps updating while you are looking at it.

  3. 3.in particular

    A 3D city map fed by a server that can hold ten thousand simultaneous connections.


note

A 3D map of Shibuya with live data streaming (hexagon heatmaps, custom GLSL effects, and per-building data), fed by a Rust5/Tokio6 WebSocket backend with 10–100× lower latency than a Python equivalent and room for 10k+ concurrent connections.

note

A 3D map of Shibuya with data arriving continuously: heat maps, custom visual effects, and figures attached to individual buildings. The server behind it is written in a fast systems language, which makes it between ten and a hundred times quicker to respond than the same thing written in a scripting language, and leaves room for ten thousand people connected at once.
