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
When launched, this sample displays a scene service with an ArcGISSceneLayer
. Pan and zoom to explore the scene.
How it works
- Create an
ArcGISScene
and set itsBasemap
withArcGISScene.setBasemap()
. - Create a
SceneView
and set the scene to the view withsceneView.setScene(scene)
. - Create an
ArcGISSceneLayer
using a data source URI:new ArcGISSceneLayer(Uri)
. - Add the new scene layer to the scene as an operational layer with
ArcGISScene.getOperationalLayers().add(sceneLayer)
.
About the data
The scene launches with a northward view of the city of Brest, France. A 3D scene layer representing buildings (some textured) is used as an example.
