I have lod2 building models loaded into 3dcitydb. What I would like to achieve is to export these buildings into tiles that are compatible with iTowns (https://www.itowns-project.org/itowns/examples/). So I think best would be .b3dm tiles and a correct tileset.json.
I have already tried to use the export-vis script of 3dcitydb. Which gives me glb files of each building separately and kml files. They are organized in a folder structure which represent tiles. However no actual glb tiles with multiple buildings on it (Each glb only contains one Building).
What is the best way to get to a tileset compatible with iTowns (or Cesium)?
