Then I applied vtkContourFilter to generate iso surface from the mask dataset. And then I tried to visualize the surface and found that the surface were discontinuous stairs. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>So I tried vtkImageReslice to resample the mask dataset and set the outputspacing to be (inputspacing[0], inputspacing[1], 1.0).
