The function fromDegreesArrayHeights() documentation (https://cesiumjs.org/Cesium/Build/Documentation/Cartesian3.html) does not indicate the unit of measure for height. I am using this to draw an orthogonal location trace from an aircraft’s altitude to the surface, and I would like the trace height to be consistent with terrainProvider effects, What units are used for the height?
By the way, is there a convenient function to get the surface height at a given location (for the ground endpoint of this orthogonal segment)?
Thank you,
