ArcGlobe开发中常用代码

ArcGlobe的强大与魅力深深地吸引着许多3DGIS初学者和开发者,现总结部分常用代码,贴出来以备大家参考,不妥之处请各位指正,
    
   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();
          
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

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

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);
        }
