ArcObjects Library Reference (3DAnalyst)

SceneGraph CoClass

A container for recording data and events that occur in a scene.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server. Requires 3D Analyst Extension.

Supported Platforms

Windows, Solaris, Linux

Extended Error Information

Use the ISupportErrorInfo method InterfaceSupportsErrorInfo to determine if the object supports extended error information. If the object supports extended error info, VC++ developers should use the OLE/COM IErrorInfo interface to access the ErrorInfo object. Visual Basic developers should use the global error object Err to retrieve this extended error information.

Remarks

SceneGraph is to Scene what MapDisplay is to Map. It's associated with a Scene object, either in ArcScene or in a scene viewer control (or a later version scene control). It handles most of the 3D rendering operations and makes the drawing more efficient.
