The use of a programmable filter is perhaps more than you actually needed, now that you know how to get the range of the input. I would start simply with the Python shell, create a contour and create its representation like this:
SetActiveSource(Input) # set your input here, if not already selected as "active" c1 = Contour() c1.Isosurfaces = [max - 0.1] Show(c1) # this will create the geometry and add it to your view Render() Otherwise, if you still want to do it with a programmable filter, you're probably missing the last two lines: c = vtk.vtkContourFilter() c.SetInput(pdo) c.SetValue(0, 0.01) c.Update() self.GetOutput().ShallowCopy(c.GetOutput()) The Update and the ShallowCopy() are the most important. ----------------- Jean M.
