Cutter.py

    # A simple script to demonstrate the vtkCutter function
    import vtk

    #Create a cube
    cube=vtk.vtkCubeSource()
    cube.SetXLength(40)
    cube.SetYLength(30)
    cube.SetZLength(20)
    cubeMapper=vtk.vtkPolyDataMapper()
    cubeMapper.SetInputConnection(cube.GetOutputPort())

    #create a plane to cut,here it cuts in the XZ direction (xz normal=(1,0,0);XY =(0,0,1),YZ =(0,1,0)
    plane=vtk.vtkPlane()
    plane.SetOrigin(10,0,0)
    plane.SetNormal(1,0,0)

    #create cutter
    cutter=vtk.vtkCutter()
    cutter.SetCutFunction(plane)
    cutter.SetInputConnection(cube.GetOutputPort())
    cutter.Update()
    cutterMapper=vtk.vtkPolyDataMapper()
    cutterMapper.SetInputConnection( cutter.GetOutputPort())

    #create plane actor
    planeActor=vtk.vtkActor()
    planeActor.GetProperty().SetColor(1.0,1,0)
    planeActor.GetProperty().SetLineWidth(2)
    planeActor.SetMapper(cutterMapper)

    #create cube actor
    cubeActor=vtk.vtkActor()
    cubeActor.GetProperty().SetColor(0.5,1,0.5)
    cubeActor.GetProperty().SetOpacity(0.5)
    cubeActor.SetMapper(cubeMapper)

    #create renderers and add actors of plane and cube
    ren = vtk.vtkRenderer()
    ren.AddActor(planeActor)
    ren.AddActor(cubeActor)

    #Add renderer to renderwindow and render
    renWin = vtk.vtkRenderWindow()
    renWin.AddRenderer(ren)
    renWin.SetSize(600, 600)
    iren = vtk.vtkRenderWindowInteractor()
    iren.SetRenderWindow(renWin)
    ren.SetBackground(0,0,0)
    renWin.Render()
    iren.Start()
