C#操作Styline二次开发实现画线功能

1：鼠标点击模型事件

 ListIPOsITion66>
     pos = new ListIPosition66>
    ();
        PRivate bool Sgworld_OnLButtonClicked(int Flags, int X, int Y)        {
                           VAR sgworld = new SGWorld66();
                var postioninfo = sgworld.Window.PixelToWorld(X, Y);
                IPosition66 ss = postioninfo.Position;
                ss.X = postioninfo.Position.X;
                ss.Y = postioninfo.Position.Y;
                pos.Add(ss);
                 return false;
        }
    　

2：操作画线

  string tMsg = String.Empty;
                ILinearRing cRing = null;
                IGeometry cPolygonGeometry = null;
                ITerrainPolyline66 cpolyo = null;
            //创建实例            //MessageBox.Show(String.Format("X:{
0}
\r\nY:{
1}
    ", posl[i].POSX, posl[i].PosX));
                var sgworld = new SGWorld66();
                ListIPosition66>
     posl = pos;
                int sin = 0;
                sin = posl.Count*3;
                double[] cVerticesArray = new double[sin];
                //获取坐标值            for (int i = 0;
     i  posl.Count;
 i++)            {
                     cVerticesArray[i*3] = posl[i].X;
                    cVerticesArray[i*3+1] = posl[i].Y;
                    cVerticesArray[i * 3 + 2] = posl[i].Altitude;
            }
             {
                    cRing = sgworld.Creator.GeometryCreator.CreateLinearRingGeometry(cVerticesArray);
                    cPolygonGeometry = sgworld.Creator.GeometryCreator.CreateLinearRingGeometry(cRing);
            }
             {
                    uint nLineColor = 0xFF00FF00;
     //颜色样式                AltitudeTyPECode AltitudeType = AltitudeTypeCode.ATC_ON_TERRAIN;
                    // D2. Create polygon                cpolyo = sgworld.Creator.CreatePolyline(cPolygonGeometry, nLineColor, AltitudeType, string.Empty, "Polygon");
                    ///注意坐标                sgworld.Window.PixelToWorld(sgworld.Window.Rect.Left, sgworld.Window.Rect.Top, WorldPointType.WPT_TERRAIN);
            }
