Open-source open-world game of real Vilnius in the browser: streamed 3D city, OSM roads, car physics — building toward a quest-based crime sandbox

First open-source workflow for converting 3DCityDB-based CityGML to Esri I3S Scene Layer Packages (SLPK). Developed at HFT Stuttgart. Paper submitted to 3DGeoInfo 2026.

Cut a neighbourhood out of a web 3D city map (I3S / 3D Tiles) and keep it as a GLB: real metres, one object per building, with names and attributes.
