In Cesium it is possible to digitise a complex polygon (with re-entrant angles) and this displays correctly on the terrain.
These coordinates can then be stored in a database as geographic (lat-long).
However if these coordinates are later loaded into Cesium and an entity is created, the polygon is not correct (polygon display has “short-cuts” and there are sometimes artefacts not tied to the terrain).
The same type of polygon loaded into Cesium ion assets as GeoJSON is OK.
Could anyone advise or make any suggestions.
Thanks,
Solved - My mistake - the polygon was loading multiple times …
