clamp cityjson object to the ground

[RAFAMATANANTSOA]

Hello everyone,
I have a CityJSON file containing buildings that is stored in my 3DCityDB database. When I display the city objects in Cesium by retrieving the geometry objects from the database, the buildings float. I would like to clamp the 3D objects to the ground, which is the ellipsoid WGS84 terrain in Cesium. Are there any tools or methods that can do this?

Thank you.

Hi @RAFAMATANANTSOA , there might be a way to fix the floating buildings in the viewer, without changing the data. I suggest that you ask on the Cesium forum https://community.cesium.com/.
