Visible geographic extent of Globe sphere.
[Visual Basic .NET] Public Sub QueryVisibleGeographicExtent ( _ ByVal Extent As IEnvelope _ )
[C#] public void QueryVisibleGeographicExtent ( IEnvelope Extent );
[C++]
HRESULT QueryVisibleGeographicExtent(
IEnvelope* Extent
);
[C++] Parameters Extent
Extent is a parameter of type IEnvelope*
The following code allows you to get the current visible geographic extent.
public void Get_VisibleGeographicExtent(IGlobe globe)
{
ESRI.ArcGIS.GlobeCore.IGlobeDisplay globeDisplay = globe.GlobeDisplay;
ESRI.ArcGIS.Analyst3D.IScene scene = (ESRI.ArcGIS.Analyst3D.IScene)globeDisplay.Scene;
ESRI.ArcGIS.Analyst3D.ISceneViewer sceneViewer = globeDisplay.ActiveViewer;
ESRI.ArcGIS.Analyst3D.ICamera camera = sceneViewer.Camera;
ESRI.ArcGIS.GlobeCore.IGlobeCamera globeCamera = camera;
ESRI.ArcGIS.GlobeCore.IGlobeViewUtil globeViewUtil = globeCamera;
ESRI.ArcGIS.Geometry.IEnvelope extent = new ESRI.ArcGIS.Geometry.EnvelopeClass();
globeViewUtil.QueryVisibleGeographicExtent(extent);
}
