1. A concise explanation of the problem you're experiencing.
Using the cesiumWorldTerrain, runways in Taiwan looks bumpy, i'd like to put an overlay with flat tiles.
I know it's possible because the project https://cesiumjs.org/demos/GEFSonline/ does this, I'd just like to know if there's any way i can accomplish this, i've looked at 3dtiles and some other stuff but i didn't find anything really relevant to my problem, or if I did I simply didn't understand.
3. Context. Why do you need to do this? We might know a better way to accomplish your goal.
I'm working on a flight simulation project, everything works fine, my plane flies in the 3D world Terrain, however, for a flight in Taiwan, the runway looks really bumpy and i'd like to have a proper flat runway,
4. The Cesium version you're using, your operating system and browser.
Cesium 1.45, Microsoft Windows 7 Enterprise, Version 6.1.7601 Service Pack 1 Build 7601. Browser: Chrome 66.
Thanks in advance,
