c#操作styline模型左键点击模型获取坐标，完成画线操作。
1：鼠标点击模型事件
List pos = new List(); 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(); List 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); }
