Display a scene with a terrain surface and some imagery.
Use case
Scene views are 3D representations of real-world areas and objects. Scene views are helpful for visualizing complex datasets where 3D relationships, topography, and elevation of elements are important factors.
How to use the sample
When opened, the sample will display a scene. Pan and zoom to explore the scene.
How it works
- Create an
AGSSceneView
object to display the map. - Create an
AGSScene
object with the.imagery()
basemap. - Set the scene to the scene view.
- Create an
AGSArcGISTiledElevationSource
object using a URL and add it to the scene's base surface.
Relevant API
- AGSArcGISTiledElevationSource
- AGScene
- AGSSceneView
