public sealed class Viewpoint

Public NotInheritable Class Viewpoint

This class allows you to store a geographic location. The ArcGIS Explorer application supports viewing a map in 2D or 3D:

• A 2D Viewpoint can be instantiated using an envelope object with optional rotation.
• A 3D Viewpoint can be instantiated using a pair of points, representing the observer and target locations. Together the observer and target determine the current view of the globe.

A Viewpoint cannot store a 2D envelope alongside 3D observer\target locations; you must choose the type of location to store when you instantiate the Viewpoint.

All MapItem types have a Viewpoint property; double clicking a MapItem in the ArcGIS Explorer contents window will go to the location defined by the MapItem.Viewpoint. The MapDisplay class also has a Viewpoint property which reflects your current view onto the map or globe.
