There’s nothing in Cesium for Unreal to do that, but CesiumJS has such a function that you could port to C++:
In CesiumJS, a Cartographic is a longitude/latitude/height where longitude and latitude are in radians (not degrees!). Heading is the angle (again, in radians!) from North (I think!). Distance is in meters.
Yeah, that got pretty intense pretty quick. There is a lot to try and digest out of all that, lot of terms that I’m not overly familiar with. Any chance that you guys are going to add this functionality to the UE code base anytime soon?
