绘制3维文字标注（IText3DElement ）

         发一个如何在ArcGLobe中绘制三维文字标注的程序，呵呵，希望和大家交流一下~~

  static  IGraphicsLayer m_GraphLayer  =   null ;
         public   static   void  Draw3DText(IGlobe pGlobe,  double  thisx,  double  thisy,  string  text,  int  Fsize,  int  red,  int  green,  int  blue)
         ... {
            if (m_GraphLayer != null)
            ...{
                IGraphicsContainer3D pGC3Da = (IGraphicsContainer3D)m_GraphLayer;
                pGC3Da.DeleteAllElements();
                 pGlobe.GlobeDisplay.RefreshViewers();
            }            

           if (m_GraphLayer == null)
            ...{
                m_GraphLayer = (IGraphicsLayer)new GlobeGraphicsLayer();
                ILayer thisilayer = (ILayer)m_GraphLayer;
                thisilayer.Name = "zapzqc";

                pGlobe.AddLayerType(thisilayer, esriGlobeLayerType.esriGlobeLayerTypeUnknown, true);
            }
            IGlobeGraphicsLayer pGL = (IGlobeGraphicsLayer)new GlobeGraphicsLayer();
            pGL = (IGlobeGraphicsLayer)m_GraphLayer;
            IPoint point = new PointClass();
            point.PutCoords(thisx, thisy);
            point.Z = 300;//控制字距离该坐标点的高度，zapzqc
            IText3DElement Ptext3DElement = new Text3DElementClass();
            Ptext3DElement.AnchorPoint = point;
            Ptext3DElement.Text = text;
            Ptext3DElement.BoldFont = true;
            Ptext3DElement.Alignment = esriT3DAlignment.esriT3DAlignHorizontal;
            Ptext3DElement.AxisRotation = esriT3DRotationAxis.esriT3DRotateAxisZ;
            Ptext3DElement.ZAxisScale = 1;
            Ptext3DElement.Justification = esriT3DJustification.esriT3DJustifyCenter;
            Ptext3DElement.Height = Fsize;
            //改变字体颜色，zapzqc
            IRgbColor Fcolor = new RgbColorClass();
            Fcolor.Red = red;
            Fcolor.Blue = blue;
            Fcolor.Green = green;
            IFillSymbol pFillSymbol = new SimpleFillSymbol();
            pFillSymbol.Color = Fcolor;
            IFillShapeElement pFillShapeElement = Ptext3DElement as IFillShapeElement;
            pFillShapeElement.Symbol = pFillSymbol;
            IGraphicsContainer3D pGC3D = (IGraphicsContainer3D)new GlobeGraphicsLayer();
            pGC3D = (IGraphicsContainer3D)m_GraphLayer; //让m_GraphLayer获得Container
            pGC3D.AddElement(pFillShapeElement as IElement);
            pGlobe.GlobeDisplay.RefreshViewers();
        }  

 这个应该还算比较简单的~~
