Andrzej, Just to make sure I understand:
vtkCpCutter calculates slices aka contours on surface and also outputs an array of "max-distance"s. You want the user to be able to see these values on the panel for this filter and then change them which in turn affects some execution logic in vtkCpCutter. Is that correct?
