[vtkusers] Error executing probeFilter pipeline

[Jothy]

Hi Guys!

I am trying to probe a imageData with probe filter

and here is the bit of that, but it throws the error following the dose.

Could you find out anything wrong?



self.LineA.SetInteractor(self.frameA.GetRenderWindow().GetInteractor())
        self.LineA.On()
        probe=vtk.vtkProbeFilter()
        line = vtk.vtkPolyData()
        probe.SetInput(self.LineA.GetPolyData(line))


        probe.SetSource(ImageData)

        tuber = vtk.vtkTubeFilter()
        tuber.SetInput(probe.GetPolyDataOutput())
        tuber.SetRadius(0.1)
        lineMapper = vtk.vtkPolyDataMapper()
        lineMapper.SetInputConnection(tuber.GetOutputPort())
        lineActor = vtk.vtkActor()
        lineActor.SetMapper(lineMapper)

        xyplot = vtk.vtkXYPlotActor()
        xyplot.AddInput(probe.GetOutput())


        ren = vtk.vtkRenderer()
        ren2 = vtk.vtkRenderer()
        renWin = vtk.vtkRenderWindow()
        renWin.AddRenderer(ren)
        renWin.AddRenderer(ren2)
        iren = vtk.vtkRenderWindowInteractor()
        iren.SetRenderWindow(renWin)

        ren.AddActor(lineActor)
        ren.AddActor2D(xyplot)

        iren.Initialize()
        renWin.Render()
        iren.Start()



ERROR: In ..\..\vtk-5.4.2\Filtering\vtkExecutive.cxx, line 757
