Scene layer selection

Identify GeoElements in a scene layer.

screenshot

How to use the sample

Click on a building in the scene layer to select it. Deselect buildings by clicking away from the buildings.

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.
