EllipsoidTerrainProvider Class
A terrain mesh provider that produces geometry that represents a smooth ellipsoid without any height perturbations. The area within the project extents are represented as planar tiles and other tiles are facetted approximations of the WGS84 ellipsoid. This is the terrain provider used when the background map is enabled but 3d terrain is disabled.

Methods
| Name | Description | |
|---|---|---|
| constructor(opts: TerrainMeshProviderOptions): EllipsoidTerrainProvider | Construct a new terrain provider. | |
| getChildHeightRange(_quadId: QuadId, _rectangle: MapCartoRectangle, _parent: MapTile): undefined | Range1d | Implements getChildHeightRange to return an empty range, because the ellipsoid is smooth. | |
| requestMeshData(): Promise<TileRequest.Response> | Implements requestMeshData to return an empty string because the mesh can be generated |
