Well, it probably confirms that the surface algorithm
used in the direct graphics surface command was state
of the art 30 years ago. Personally, I don't think it
was designed to display the kind of surface you appear
determined to display. Time to learn about object
graphics, I'd say. :-)
Cheers,

P.S. Have you tried the iSurface tool? No one will be
able to help you program the darn thing, but maybe it
will do your display correctly.
