Add a scene layer to a scene.
Use case
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
Run the sample to display a scene service with an ArcGISSceneLayer. Pan and zoom to explore the scene.
How it works
- Create an
ArcGISScenehaving aBasemapStyle.ArcGISTopographic. - Create a
SceneViewand set the scene to the view. - Create an
ArcGISSceneLayerusing a data source URI:ArcGISSceneLayer(Uri). - Add the new scene layer to the scene as an operational layer with
scene.operationalLayers.add(sceneLayer).
Relevant API
- ArcGISScene
- ArcGISSceneLayer
- SceneView
About the data
The scene launches with a northward view of the city of Brest, France (SceneServer). A 3D scene layer representing buildings (some textured) is used as an example.
Additional information
This sample uses the GeoViewCompose Toolkit module to be able to implement a Composable SceneView.
