Add a scene layer to a scene.

Image of scene layer

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 an ArcGISScene and set its Basemap with ArcGISScene.setBasemap().
  2. Create a SceneView and set the scene to the view with sceneView.setScene(scene).
  3. Create an ArcGISSceneLayer using a data source URI: new ArcGISSceneLayer(Uri).
  4. Add the new scene layer to the scene as an operational layer with ArcGISScene.getOperationalLayers().add(sceneLayer).

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.
