This code sample is available for these platforms:
View Sample on GitHub

Display an ArcGIS scene layer from a URL.

screenshot

How to use the sample

Pan and zoom to explore the scene.

How it works

  1. Create an ArcGISSceneLayer passing in the URL to a scene layer service.
  2. Wait for the user to tap with the sceneView.GeoViewTapped event and get the tapped screen point.
  3. Call sceneView.IdentifyLayersAsync(sceneLayer, screenPoint, tolerance, false, 1) to identify features in the scene.
  4. From the resulting IdentifyLayerResult, get the list of identified GeoElements with result.GeoElements.
  5. Get the first element in the list, checking that it is a feature, and call sceneLayer.SelectFeature(feature) to select it.
