arcglobe二次开发实习指导书

二次开发实习指导书掌握Globe场景数据导入、不同图层类型的控制方掌握Globe工 管理控件及右键控制图层功能的添加方法掌握更改图层属性、、高程设置等Globe图层属性的设置方法掌握在Globe场景中添加三维注记与三维模型的方实习环软ArcEngine10.0硬实习方数据导入了解Globe场景图层类型数据导入分类的基本流程：加载数据Globe图层分类其C#函数使用方法如下。其中TLayer为添加的数据图层，GlobeLayerType则为该图层指基于上面知识，现在进行编程开发。启动VisualStudio2008，文件->新建->项目，在项目类型中，选择VisualC#语言，在ArcGIS中选择ExtendingArcObjects，然后在VisualStudio已按照的模板中，选择GlobeControlApplication，可选填自定义名称，如下图中privatevoid加载栅格文件到漂浮图层{Item_Click(objectsender,EventArgsprivatevoid加载栅格文件到漂浮图层{Item_Click(objectsender,EventArgsOpenFileDialogFilePath=newOpenFileDialog();FilePath.FileName="";FilePath.ShowReadOnly=false;FilePath.FilterIndex=1;FilePath.Title="打开栅格文件if(FilePath.ShowDialog()=={IRasterLayertempRaster=new//IRasterLayer需要 GlobeLayerTypeFloating, }}如何加入Shp要素文件如何查看效果？（提示：缩放到图层 IToolbar接口：其作用为可支持Command,Tool,ToolControl,MultiItemand添加新建项ArcGISExtendingArcObjectsBaseCommad，新建名称ZoomToLayer，确定后弹出来的界面为选择ArcGlobeorGlobeControlCommand，建立ZoomToLayer.cs。basem_caption"缩放到图层";//localizablepublicbasem_caption"缩放到图层";//localizablepublicoverridevoidOnCreate(object{}publicoverridevoid{在ZoomToLayer.cs中的如下函数中实现缩放到图层控制。注意添publicoverridevoid{ yer=.ArcGIS.Carto.ILayeryst3D.ISceneViewersceneViewer= yst3D.ICamera= .ArcGIS.GlobeCore.IGlobeCameraglobeCamera }在完成ZoomToLayer控件定义后，接着在MainForm.cs中，定义全局私有变 //用//用于TOCControl右键菜privateITOCControl2m_tocControl;private 然后在MainForm.cs的MainForm_Load函数中初始化，添加右键菜单privateprivatevoidMainForm_Load(objectsender,EventArgs{… 栏控 Layernew Class();//}//{if(e.button!=2)TOCControlItemitem{if(e.button!=2)TOCControlItemitem=IBasicMapmap=null;ILayerlayer=null;objectother=null;objectindex=m_tocControl.HitTest(e.x,e.y,refitem,refmap,reflayer,refother,refif(item== m_tocControl.SelectItem(map,null);=;(if(item{}(ex,e.y,m_tocControl.hWnd);//弹出右键菜}} “选择重定义菜单类型”publicvoidSetTextureLayer(IGlobeControlm_pGlobeControl, {IGlobeLayerPropertiespublicvoidSetTextureLayer(IGlobeControlm_pGlobeControl, {IGlobeLayerProperties yLayers yLayers= pGlobeLayerPropertiespGlobeLayerProperties= pGlobeLayerProperties.Type }新建Command接口：工程添加新建项ArcGISExtendingpublicoverridevoid{ yer= publicoverridevoid{ yer= _3DFunctionGisFunction=new_3DFunction(); }privatevoidMainForm_Load(objectsender,privatevoidMainForm_Load(objectsender,EventArgs{……}Layer.AddItem(newSetTextureLayer(),-1,1,IGlobeDrawingOrderpublicoverridevoid{ yer= _3DFunctionGisFunction=new_3DFunction(); publicoverridevoid{ yer= _3DFunctionGisFunction=new_3DFunction(); }privatevoidMainForm_Load(objectsender,EventArgs{……}添privatevoidMainForm_Load(objectsender,EventArgs{……}三维文字IText3DElementIRgbColor接口：使用RGBIGradientFillSymbol,ISimpleFillSymbol,IPictureFillSymbol。publicvoidDraw3DText2(IGlobeGraphicsLayerpGL,IGlobepGlobe,doublethisx,doublepublicvoidDraw3DText2(IGlobeGraphicsLayerpGL,IGlobepGlobe,doublethisx,doublestringtext,intFsize,intred,intgreen,int{IPointpoint=newPointClass();point.PutCoords(thisx,thisy);Ptext3DElement.AnchorPoint=point;Ptext3DElement.Text=text;Ptext3DElement.Alignment= Ptext3DElement.AxisRotation= Ptext3DElement.ZAxisScale=1;Ptext3DElement.Justification= Ptext3DElement.Height=Fsize;Fcolor.Red=red;Fcolor.Blue=blue;pFillSymbol.Color=Fcolor;IFillShapeElementpFillShapeElement=Ptext3DElementasIFillShapeElement;pFillShapeElement.Symbol=pFillSymbol;IGraphicsContainer3DpGC3D=(IGraphicsContainer3D)newGlobeGraphicsLayer();pGC3D=(IGraphicsContainer3D)pGL; }在工程中，右键选择MainForm.cs，视图设计器privatevoid添加三维注记{Item_Click(objectprivatevoid添加三维注记{Item_Click(objectsender,EventArgsIGlobeGraphicsLayerm_globeGraphicsLayer2newGlobeGraphicsLayerClass();((ILayer)m_globeGraphicsLayer2).Name="动态图层";IScenescene= scene.AddLayer((ILayer)m_globeGraphicsLayer2,false); _3DFunctionGisFunction=newGisFunction.Draw3DText2(m_globeGraphicsLayer2,axGlobeControl1.Globe,-82,30,"地理信息系统2010年级 ,255,0,}(.3ds),or(VRML*)等格式外部模型作为一个点符号。3） cement接口：用于三维标记符号的空间位置属性设置。其QueryRotationAngles和SetRotationAngles设置或获取在X、Y、Z上的旋转角度publicvoidAddModel(IGlobeGraphicsLayer{IMarker3DSymbolpMarker3DSymbolnewMarker3DSymbolClass();publicvoidAddModel(IGlobeGraphicsLayer{IMarker3DSymbolpMarker3DSymbolnewMarker3DSymbolClass(); cement cement=pMarker3DSymbolas IGeometrytempGeometry=pMarker3D IEnvelopetempEnvelop=tempGeometry.Envelope;cement.Size=tempEnvelop.Depth*500000;cement.Depth=tempEnvelop.Height*500000;cement.Width=tempEnvelop.Width*cement.MaintainAspectRatio=cement.SetRotationAngles(0,0,cement.XOffset=cement.YOffset=cement.ZOffset=//cratethegraphicIElementtrackElement=newMarkerElementClass();((IMarkerElement)trackElement).Symbol=pMarker3D //createanewpointatthegivenpositionIPointpoint=newPointClass();((IZAware)point).ZAware=true;point.X=110.0;point.Y=point.Z=trackElement.Geometry=pointasIPoint;globeGraphicsLayer.FindElementIndex(trackElement,globeGraphicsLayer.FindElementIndex(trackElement,out}privatevoid添加三维模型{Item_Click(objectprivatevoid添加三维模型{Item_Click(objectsender,EventArgsIGlobeGraph
