I'm visualizing a vtkUnstructuredGrid box (opacity 0.3), and inside the 
norm of the coordinate field by contour surface.
I do no understand why the faces of the vtkUnstructuredGrid produced by 
the contour filter are not well oriented, because  when I assign to this 
grid an opacity of  0.5, I get an horrible view, where the order of 
display seems to be corrupt. You can see that in the attachment
What can I do. Is there a filter that re orient the faces of a grid ? Is 
there a link with face culling ?
Thanks for help
