In this example, the color of each surface of the 3D Tiles models is based on the CityGML class of the surface. CityGML classes of all surfaces are stored in the Batch Table.
The tileset was created with Py3DTilers, an open source toolkit to create 3D Tiles out of various geometrical formats (OBJ, GeoJSON, IFC or CityGML), using the CityTiler.
CityGML models are from open data and can be found online: Lyon 1 CityGML (year 2018) of Data Grand Lyon.
To install and use Py3DTilers, see online documentation: installation & usage.
The command used to created the tileset is:
citygml-tiler -i py3dtilers/CityTiler/CityTilerDBConfig.yml --type building --add_color --split_surfaces -o Lyon-1_2018_CityGML_ColorsThe tileset is available online here
