Billboard on terrain

How can I add a billboard on top of terrain? I assume I can get terrain height somehow?

Found it. http://cesium.agi.com/Cesium/Build/Documentation/sampleTerrain.html?classFilter=&show=all

Does anyone have a snippet of code to do the call back needed to return the height value?

Hey Todd,

There’s a snippet of code in the documentation you linked that shows how to attach a callback to the promise. Let me know if anything is unclear.
