Display an ArcGIS scene layer from a URL.
Use case
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 ArcGIS Maps SDK. Loading a scene layer from a URL also permits the layer source to change dynamically without updating the code. 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
Pan and zoom to explore the scene.
How it works
- Create an
ArcGISSceneLayerpassing in the URL to a scene layer service. - Create a
Sceneand add the scene layer to its operational layers. - Create a
Surfaceobject and add anArcGISTiledElevationSourceto it. - Set the surface to the scene's base surface.
- Create a
SceneViewwith the scene.
Relevant API
- ArcGISSceneLayer
- ArcGISTiledElevationSource
