Add a scene layer to a scene.

Use case

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

  1. Create a Scene and set its Basemap.
  2. Create a Surface and add an elevation source to it.
  3. Add the created surface to the scene.
  4. Create a SceneView and set the scene to the view.
  5. Create an ArcGISSceneLayer using a data source URL.
  6. Add the new scene layer to the scene as an operational layer.

About the data

The scene launches with a northward view of the city of Brest, France. A 3D scene layer representing buildings (some textured) is used as an example.
