Hi,
I'm a Master's student using FME Workbench for my thesis project, and I'm using the Cesium 3D Tiles writer to convert CityGML files into Cesium 3D Tilesets. I am curious how the writer determines which features should go into which tiles? The Cesium 3D Tiles spec states that tiles are loaded roughly by distance to the camera; however, when I convert a large CityGML dataset to a 3D Tiles dataset, the writer scatters features over a large geographical area rather than clustering them together based on spatial location. I was also wondering how the writer calculates the bounding volume property of 3D tiles, as the bounding volume shows up as a very large box tilted at an angle. I would appreciate any insight anyone might have on how the 3D Tiles writer determines bounding volumes and how it determines which features are assigned to which tile.Thanks!
