The tiling scheme defines how tile based data is rendered. The tiling scheme property is used by the SceneView to determine how to render tiled data.

This property is determined during GeoModel.load(). The SpatialReference of the first tiled elevation source (ArcGISTiledElevationSource) or tiled layer in the basemap or operational layer (see ArcGISTiledLayer) determines whether the value is SceneViewTilingScheme.Geographic or SceneViewTilingScheme.WebMercator.

If you create a new scene, you can set this value before adding the base surface, basemap or operational layers. The SceneViewTilingScheme must correspond to the SpatialReference of the layers to ensure they render correctly.

The default value is SceneViewTilingScheme.WebMercator.
