<div dir="ltr"><div>Hi All,</div>
<div> </div>
<div>I want to get the center fo the vtkbox widget at the beginning of moving it and at the end of moving it</div>
<div> </div>
<div>I tried adding two observers one at interaction event and the second at the Endinteraction event , but unfortunatly the center result from both of thoses are the same </div>
<div> </div>
<div>any suggestion to solve that </div>
<div> </div>
<div> public static void InteractionEvent(vtk.vtkObject obj, uint eventId, Object data, IntPtr clientdata)<br>        {<br>            vtkBoxWidget widget = vtkBoxWidget.SafeDownCast(obj);<br>            widget.GetPlanes(planes);<br>
            selectActor.VisibilityOn();</div>
<div> </div>
<div><br>            vtkPolyData before = new vtkPolyData();<br>            widget.GetPolyData(before);<br>            center_Before = GetBoundsCenter(before.GetBounds());</div>
<div><br>            //maceActor.VisibilityOff();<br>            ///////////// Test writting /////////////////////////////////////////////<br>            //Write the file</div>
<div><br>            /*vtkXMLPolyDataWriter writer = new vtkXMLPolyDataWriter ();<br>            writer.SetInputConnection(clipper.GetOutputPort());<br>           writer.SetFileName(&quot;disk.vtp&quot;);<br>           writer.Write();*/</div>

             widget.GetPolyData(after);<br>             center_After = GetBoundsCenter(after.GetBounds());</div>
<div><br>             ModifyData();</div>
<div> </div>
<div><br>        }</div>
<div><br>        private static double[] GetBoundsCenter(double[] bounds)<br>        {<br>            double[] center = new double[3];</div>
<div><br>            center[0] = (bounds[0] + bounds[1]) / 2.0;<br>            center[1] = (bounds[2] + bounds[3]) / 2.0;<br>            center[2] = (bounds[4] + bounds[5]) / 2.0;</div>
