sampleHeight
fun sampleHeight(position: Cartographic, objectsToExclude: ReadonlyArray<Any>? = definedExternally, width: Double? = definedExternally): Double(source)
Returns the height of scene geometry at the given cartographic position or undefined if there was no scene geometry to sample height from. The height of the input position is ignored. May be used to clamp objects to the globe, 3D Tiles, or primitives in the scene.
This function only samples height from globe tiles and 3D Tiles that are rendered in the current view. Samples height from all other primitives regardless of their visibility.
const position = new Cartographic(-1.31968, 0.698874);

Return
The height. This may be undefined if there was no scene geometry to sample height from.
Parameters
position
The cartographic position to sample height from.
objectsToExclude
A list of primitives, entities, or 3D Tiles features to not sample height from.
width
Width of the intersection volume in meters. Default value - 0.1
