Display a scene | ArcGIS Maps SDK for Qt

View on GitHub Sample viewer app

Display a scene with a terrain surface and imagery.

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.

When loaded, the sample will display a scene. Pan and zoom to explore the scene.

1. Create a Scene object with a basemap using the BasemapStyle::ArcGISImagery BasemapStyle.
2. Create an ArcGISTiledElevationSource object and add it to the scene's base surface.
3. Create a SceneView object to display the map.
4. Set the scene to the scene view.
