I'm trying to make a Cesium-based 3D web-viewer. At the moment I'm stuck with an error. Let me describe the situation:
I have a PostGIS database, containing the 3D geometry of a building (which I extracted from my main database, containing many more building geometries).
I have entered this database into Geoserver 2.7.2.
I wrote a simple Cesium script calling the WMS which is serving the database.
Error: error occurred in "v": Failed to obtain image tile X : 0 Y : 0 Level : 0.
Now, I read some things on this error, something about missing top level tiles. But all this internet literature seems to be about terrains, but that is not what I am doing.
Is there someone who can explain me what is going wrong?
