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
- Create a
Scene
object with a topographic basemap style. - Create a
Surface
object and add anArcGISTiledElevationSource
to it. - Set the surface to the scene's base surface.
- Create an
ArcGISSceneLayer
with a URL and add it to the scene's operational layers. - Create a
SceneView
with the scene.
Relevant API
- ArcGISSceneLayer
- Scene
- SceneView
