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 with Scene::setBasemap().
  2. Create a Surface and add an elevation source to it: surface::elevationSources()::append(arcGISTiledElevationSource).
  3. Add the created surface to the scene: Scene::setBaseSurface(surface).
  4. Create a SceneView and set the scene to the view with SceneView::setArcGISScene(scene).
  5. Create an ArcGISSceneLayer using a data source URL: new ArcGISSceneLayer(URL).
  6. Add the new scene layer to the scene as an operational layer with ArcGISScene::operationalLayers()::append(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.
