Hi,  
I'm trying to load GML files into Cesium. I read that we can do it using 3D tiles. Cesium 3D tiles have separate branch, as its not yet merged with Cesium yet.

I couldn't find enough samples to implement above. 3D tiles with CityGML.  
I Also found some conversion tools, which converts GML files into KML/COLLADA file and then we can render them in Cesium.

Let me know if anyone tried to use GML files in Cesium.

I’m not aware of any public CityGML/GML to 3D Tiles converters, however COLLADA can be converted to glTF with [COLLADA2GLTF](https://github.com/KhronosGroup/COLLADA2GLTF) which is the primary component of a b3dm tile.
