ArcGlobe开发中常用代码

Code
 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

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

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();

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 =

            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

ESRI.ArcGIS.GlobeCore.esriGlobeLayerType globeLayerType, ESRI.ArcGIS.Carto.ILayer layer)
        {
            if (globe == null || layer == null ||
                globeLayerType ==

ESRI.ArcGIS.GlobeCore.esriGlobeLayerType.esriGlobeLayerTypeElevation ||
                globeLayerType ==

ESRI.ArcGIS.GlobeCore.esriGlobeLayerType.esriGlobeLayerTypeUnknown)
            {
                return;
            }

            ESRI.ArcGIS.GlobeCore.IGlobeDisplay globeDisplay = globe.GlobeDisplay;
            ESRI.ArcGIS.GlobeCore.IGlobeDisplay2 globeDisplay2 = globeDisplay as

ESRI.ArcGIS.GlobeCore.IGlobeDisplay2;
            globeDisplay2.PauseCaching = true;
            globe.AddLayerType(layer, globeLayerType, true);
            ESRI.ArcGIS.GlobeCore.IGlobeDisplayLayers globeDisplayLayers = globeDisplay as

ESRI.ArcGIS.GlobeCore.IGlobeDisplayLayers;
            ESRI.ArcGIS.GlobeCore.IGlobeLayerProperties globeLayerProperties =

globeDisplayLayers.FindGlobeProperties(layer);
            globeLayerProperties.IsDynamicallyRasterized = false;
            globeDisplay2.PauseCaching = false;
        }


经过几天的忙碌,又除去了网站程序中的一些Bug ,现在总结出ArcEngine三维开发控件ArcGlobe的一些常用代码,张贴出来以飨大家,其中疏漏之处,恳请指正!
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);
        }
