Add scene layer from service

View on GitHub

Display an ArcGIS scene layer from a service.

Use case

Adding a scene layer from a service allows you to author the scene layer elsewhere in the platform, say with ArcGIS Pro or CityEngine, and then add that scene layer to a scene in ArcGIS Maps SDK. Loading a scene layer from a service also permits the layer source to change dynamically without updating the code.

How to use the sample

Pan and zoom to explore the scene.

How it works

  1. Create a Scene object with a topographic basemap style.
  2. Create a Surface object and add an ArcGISTiledElevationSource to it.
  3. Set the surface to the scene's base surface.
  4. Create an ArcGISSceneLayer with a URL and add it to the scene's operational layers.
  5. Create a SceneView with the scene.
