Working with a 3D view is much like working with a 2D view. For example, both views share the same implementation for layers, renderers, tasks, geometry, symbology, popups, and navigation, but 3D adds 3D-specific concepts such as environment (atmosphere and lighting) and the camera. This extra 3D capability is what we'll cover in this section.
A scene is symbolized 3D geospatial content that includes a multiscale basemap, a collection of 2D and 3D layers, styles, and configurations that allow you to visualize and analyze geographic information in an intuitive and interactive 3D environment. You can author these scenes either in the ArcGIS Online or Portal Scene Viewer software, or on the desktop using ArcGIS Pro.
