A procedural 3D Tokyo simulation in Three.js

Opus 5.5 helped me build Tokyo in the browser with @threejs by compiling open data - PLATEAU's 3D city model, OpenStreetMap and GSI elevation and aerial photos into streaming tiles, with procedural shader facades, generated road markings, signal-obeying traffic and trains. Also added @Takram's volumetric clouds which cast shadows on the streets.
