Adding a scene layer from a URL 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 Runtime. Loading a scene layer from a URL 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 an AGSScene with a topographic basemap.
Apply the scene to an AGSSceneView.
Create an AGSArcGISTiledElevationSource with a URL and add it to an AGSSurface.
Apply the surface to the scene.
Create an AGSArcGISSceneLayer with a URL and add it to the scene's operationalLayers array.
