Trees in Cesium from point Shapefile > CityGML > Cesium

Hi Cesium Team,

I read the last comment from this thread.

Instanced 3D Tiles

Can you tell me a bit more about that? If there’s a missing feature or an issue you ran into we’d love to know. Cesium ion automatically chooses the tile format to give you the best performance. What format is your source data? If you’re using CityGML or KML/COLLADA, and you have one model repeated in many different locations, that’ll be instanced in the final 3D Tileset. This is how this Switzerland government portal set up its viewer with 70 million trees/houses etc: https://www.swisstopo.a…

I want to visualize trees that are originally from points in a shapefile format. I also have an fbx file of a tree. I want to use this fbx model repeatedly to visualise all the trees. I am still researching on how to convert the sahpefile into CityGML and finally visualize it with CesiumJS. I am thingking to use the 3DCityDB Importer/Exporter tool to export the CityGML to 3D Tiles format so that it can be visualised in CesiumJS.

Do you have any idea or sources that I can read about how to generate CItyGML file from a shapefile and then use the file for the visualisation CesiumJS ?

Thanks
