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 loaded, the sample will display a scene. Pan and zoom to explore the scene.
How it works
- Create a
Scene
object witharcGISImageryStandard
basemap style. - Create a
Surface
object. - Add an
ArcGISTiledElevationSource
object to the surface. - Set the surface to the scene's base surface.
- Create a
SceneView
instance with the scene.
Relevant API
