这是常用的ArcGlobe代码。可以拿出来分析一下：

ArcGlobe常用代码:

1.按照适当的顺序绘制ArcGlobe图层

public void GetSetGlobeDrawingOrder(ESRI.ArcGIS.GlobeCore.IGlobe globe)

        {

            ESRI.ArcGIS.GlobeCore.IGlobeDisplay globeDisplay = globe.GlobeDisplay;

            ESRI.ArcGIS.GlobeCore.IGlobeDrawingOrder globeDrawingOrder = (ESRI.ArcGIS.GlobeCore.IGlobeDrawingOrder)globe;

ESRI.ArcGIS.Carto.IEnumLayer enumLayer = globeDrawingOrder.OrderedLayers;

ESRI.ArcGIS.Carto.IEnumLayer baseLayers = globe.get_GlobeLayers(null, true, true, true);

ESRI.ArcGIS.Carto.IEnumLayer floatingLayers = globe.get_GlobeLayers(null, false, false, true);

ESRI.ArcGIS.GlobeCore.IGlobeLayerProperties globeLayerProperties;

ESRI.ArcGIS.GlobeCore.IGlobeDisplayLayers globeDisplayLayers = (ESRI.ArcGIS.GlobeCore.IGlobeDisplayLayers)globeDisplay;

System.Collections.ArrayList DrapedLayers = new System.Collections.ArrayList();

System.Collections.ArrayList ElevationLayers = new System.Collections.ArrayList();

ESRI.ArcGIS.Carto.ILayer layer = baseLayers.Next();

            while (layer != null)

            {

                globeLayerProperties = globeDisplayLayers.FindGlobeProperties(layer);

                if (globeLayerProperties.Type != ESRI.ArcGIS.GlobeCore.esriGlobeDataType.esriGlobeDataElevation)

                {

                    DrapedLayers.Add(layer);

                }

                else if (globeLayerProperties.Type == ESRI.ArcGIS.GlobeCore.esriGlobeDataType.esriGlobeDataElevation)

                {

                    ElevationLayers.Add(layer);

                }

                //获得下一层

                layer = baseLayers.Next();

            }

            ESRI.ArcGIS.Carto.ILayer theDrapedLayer = (ESRI.ArcGIS.Carto.ILayer)DrapedLayers[0];

            globeDrawingOrder.MoveBackward(theDrapedLayer);

            globeDisplay.RefreshViewers();

            //获得浮动图层

            ESRI.ArcGIS.Carto.ILayer theFloatingLayer = floatingLayers.Next();

            while (theFloatingLayer != null)

            {

                theFloatingLayer = floatingLayers.Next();

            }

        }

2.获得BasicMap

public ESRI.ArcGIS.Carto.IBasicMap GetBasicMapFromGlobe(ESRI.ArcGIS.GlobeCore.IGlobe globe)

        {

            ESRI.ArcGIS.Carto.IBasicMap basicMap = globe as ESRI.ArcGIS.Carto.IBasicMap;

            return basicMap;

        }

3.获得Geographic 坐标

public ESRI.ArcGIS.Geometry.IPoint GetGeographicCoordinates(System.Int32 xView, System.Int32 yView, ESRI.ArcGIS.GlobeCore.IGlobeDisplay globeDisplay)

        {

            ESRI.ArcGIS.Geometry.IPoint point;

            object ppOwner;

            object ppObject;

            globeDisplay.Locate(globeDisplay.ActiveViewer, xView, yView, false, true, out point, out ppOwner, out ppObject);

            return point;

        }

4.设置Globe Layer 属性

public void SetGlobeLayerProperties1(ESRI.ArcGIS.GlobeCore.IGlobeDisplay globeDisplay, ESRI.ArcGIS.Carto.ILayer layer)

        {

            ESRI.ArcGIS.GlobeCore.IGlobeDisplayLayers globeDisplayLayers = globeDisplay as ESRI.ArcGIS.GlobeCore.IGlobeDisplayLayers;

            ESRI.ArcGIS.GlobeCore.IGlobeLayerProperties globeLayerProps = globeDisplayLayers.FindGlobeProperties(layer);

            globeLayerProps.Use16ColorBits = true;

            globeDisplayLayers.RefreshLayer(layer);

        }

 

1.向ArcGlobe控件中通过类型来添加图层

public void AddGlobeLayerByType(ESRI.ArcGIS.GlobeCore.IGlobe globe,

ESRI.ArcGIS.GlobeCore.esriGlobeLayerType globeLayerType, ESRI.ArcGIS.Carto.ILayer layer)

        {

            if (globe == null) return;

            if (globeLayerType ==

ESRI.ArcGIS.GlobeCore.esriGlobeLayerType.esriGlobeLayerTypeElevation)

            {

                if (layer is ESRI.ArcGIS.Carto.IRasterLayer ||

                    layer is ESRI.ArcGIS.Carto.ITinLayer ||

                    layer is ESRI.ArcGIS.Carto.ITerrainLayer)

                {

                    globe.AddLayerType(layer, globeLayerType, true);

                }

                return;

            }

            // else if GlobeLayerType is esriGlobeLayerTypeDraped or

esriGlobeLayerTypeFloating

            globe.AddLayerType(layer, globeLayerType, true);

        }

     2.向ArcGlobe中添加Graphics Layer

graphicsLayerName)

        {

            // 创建graphics layer 并添加到 ArcGlobe

            ESRI.ArcGIS.Carto.IGraphicsContainer globeGraphicsLayer = new

ESRI.ArcGIS.GlobeCore.GlobeGraphicsLayerClass();

            ESRI.ArcGIS.Carto.ILayer layer = (ESRI.ArcGIS.Carto.ILayer)globeGraphicsLayer;

           layer.Name = graphicsLayerName;

            ESRI.ArcGIS.Analyst3D.IScene scene = globe as ESRI.ArcGIS.Analyst3D.IScene;  

               

            scene.AddLayer(layer, true);

            // 向graphics layer添加点元素

            ESRI.ArcGIS.Carto.IElement markerElement = new

ESRI.ArcGIS.Carto.MarkerElementClass();

            ESRI.ArcGIS.Analyst3D.ISimpleMarker3DSymbol simpleMarker3DSymbol = new

ESRI.ArcGIS.Analyst3D.SimpleMarker3DSymbolClass();

            simpleMarker3DSymbol.Style =

ESRI.ArcGIS.Analyst3D.esriSimple3DMarkerStyle.esriS3DMSCone;

            // 设置相关属性

            simpleMarker3DSymbol.ResolutionQuality = 1;

            ESRI.ArcGIS.Display.IColor rgbColor = new ESRI.ArcGIS.Display.RgbColorClass();

            rgbColor.RGB = 255;

            ESRI.ArcGIS.Display.IMarkerSymbol markerSymbol =

(ESRI.ArcGIS.Display.IMarkerSymbol)simpleMarker3DSymbol;             markerSymbol.Color =

rgbColor;

            markerSymbol.Size = 100000;

          

            ESRI.ArcGIS.Geometry.IPoint point = new ESRI.ArcGIS.Geometry.PointClass();

            point.PutCoords(-47, 44);

            markerElement.Geometry = point;

            // 添加到 graphics layer

            ESRI.ArcGIS.Carto.IMarkerElement markerElement_2 =

(ESRI.ArcGIS.Carto.IMarkerElement)markerElement;

            markerElement_2.Symbol = markerSymbol;

            globeGraphicsLayer.AddElement(markerElement, 1);

            // 向graphics layer添加线元素

            ESRI.ArcGIS.Carto.IElement lineElement = new

ESRI.ArcGIS.Carto.LineElementClass();

            ESRI.ArcGIS.Analyst3D.ISimpleLine3DSymbol simpleLineSymbol3D = new

ESRI.ArcGIS.Analyst3D.SimpleLine3DSymbolClass();

            simpleLineSymbol3D.Style =

ESRI.ArcGIS.Analyst3D.esriSimple3DLineStyle.esriS3DLSStrip;

            //设置颜色和大小

            simpleLineSymbol3D.ResolutionQuality = 1;

            rgbColor.RGB = 255000;

            ESRI.ArcGIS.Display.ILineSymbol lineSymbol = (ESRI.ArcGIS.Display.ILineSymbol)

simpleLineSymbol3D;

            lineSymbol.Color = rgbColor;

            lineSymbol.Width = 2;

            // 设置geometry

            ESRI.ArcGIS.Geometry.IPolyline polyline = new

ESRI.ArcGIS.Geometry.PolylineClass();

            ESRI.ArcGIS.Geometry.IPoint fromPoint = new ESRI.ArcGIS.Geometry.PointClass();

            fromPoint.PutCoords(-30, 44);

            polyline.FromPoint = fromPoint;

            ESRI.ArcGIS.Geometry.IPoint toPoint = new ESRI.ArcGIS.Geometry.PointClass();

            toPoint.PutCoords(-60, 44);

            polyline.ToPoint = toPoint;

            lineElement.Geometry = polyline;

            // 添加到 graphics layer

            ESRI.ArcGIS.Carto.ILineElement lineElement_2 =

(ESRI.ArcGIS.Carto.ILineElement)lineElement;

            lineElement_2.Symbol = lineSymbol;

            globeGraphicsLayer.AddElement(lineElement, 1);

        }

     3.向ArcGlobe添加 KML 数据

public void AddKMLData(System.String theKmlFile, ESRI.ArcGIS.GlobeCore.IGlobe globe,

System.String kmlLayerName)

        {

            Type kmlType = Type.GetTypeFromProgID("esriGlobeCore.KmlLayer");

            ESRI.ArcGIS.GlobeCore.IKmlLayer kmlLayer = (ESRI.ArcGIS.GlobeCore.IKmlLayer)

System.Activator.CreateInstance(kmlType);

            kmlLayer.DataPath = theKmlFile;

            kmlLayer.Name = kmlLayerName;

            ESRI.ArcGIS.Analyst3D.IScene scene = globe as ESRI.ArcGIS.Analyst3D.IScene;  

         scene.AddLayer(kmlLayer as ESRI.ArcGIS.Carto.ILayer, true);       

         }

    4.向ArcGlobe中添加矢量数据
