How about substituting Band for Isosurface? Ideally, you would then get solid colored bands demarking regions of data values instead of lines.
Is this blade incredibly thin (like one tiny tetrahedron thick)? That still doesn't tell me why the lines should do what they do, but I'm just wondering if you are approaching the resolution limit of the camera; that is if the difference between front and back drops below the resolution of float (or double, can't remember what the camera uses internally) at that distance from the lens. When you zoom in, this apparent difference is larger and you may be crossing the threshold back to something thick enough for camera to figure out which is front and back.
For yucks, try switching to perspective camera (Image:View Control pull-down menu).
How big is the data file? If emailable, I would be intrigued to take a look at it with the net you are using, as well as this would test it on completely different hardware (OS X and G5), unless one of the new suggestions fixes things. (Warning: I'm out of the office for the next 4 days).

Ok, some light started to shine! Thanks for the suggestions!_______________________________
As you probably can see from
http://www.fm.vok.lth.se/Staff/Priv/DM/water-turbine.html
the problem still persists. The light that I mentioned was about the fact that
I noticed with the connections. If the picture is small they start to mix
front with back, but not as much as in the case with isolines. Anyway, when I
zoom in, the the triangles start to be cristal clear. Following this, I have
zoomed in also the picture with the isolines and the interferences
dissapeared.
Now my problem is what can I do to have nice isolines?
I tested the net on two different machines, one with nvidia graphic card and
another with i810 graphic card, and the result was the same. I run linux on
both machines but one is debian woody with 2.4.26 kernel and second with
slackware 10.0 with 2.6.10 kernel.
The option that you mention for the Isosurface control, I did not set, to be
onest I did not know there is such an option before.
Can you give me other hint to what I can do, or how to present this picture in
order to look nice? I tried to put an AutoColor directly after the
ShowBoundary, and the result is what you see in the first picture. It is nice
and is not mixing again the two surfaces but it is no longer as clear as it
would be with the isolines.
Thank you,
