Select features in scene layer

Identify features in a scene to select.

Use case

You can select features to visually distinguish them with a selection color or highlighting. This can be useful to demonstrate the physical extent or associated attributes of a feature, or to initiate another action such as centering that feature in the scene view.

How to use the sample

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

How it works

1. Create an instance of ArcGISSceneLayer, passing in the URL to a scene layer service.
2. Use the onSingleTapGesture on the SceneView to get the screen tapped location.
3. Use SceneViewProxy.identify(layer:screenPoint:tolerance:maximumResults:) to identify features in the scene.
4. From the resulting IdentifyLayerResult, get the list of identified GeoElements.
5. Get the first Feature in the list and use ArcGISSceneLayer.selectFeature(features:).
