Each scene layer added to a scene can assist in performing helpful visual analysis. For example, if presenting the results of a shadow analysis of a major metropolitan downtown area in 3D, adding a scene layer of 3D buildings to the scene that could be toggled on/off would help to better contextualize the source of the shadows.
How to use the sample
When launched, this sample displays a scene service with an ArcGISSceneLayer. Pan and zoom to explore the scene.
How it works
Create a Scene and set its Basemap.
Create a Surface and add an elevation source to it.
Add the created surface to the scene.
Create a SceneView and set the scene to the view.
Create an ArcGISSceneLayer using a data source URL.
Add the new scene layer to the scene as an operational layer.
