Thank you Karl for some explan- and clarifcation.
Still I have some problems. The stated example was given since my results
in real data, say 128x128x99 or 512x512x99 volumes with greyvalues
overpowdered with some noise will produce and have produced quite
arbitrary results since this example situation with values at the border
of the (expected) surface appears arbitrarily often.
My solution was then to generate first a binary volume and then apply
ISOSURFACE or anything else. The result was of course disastrous,
following this lt/le dichotomy.
However that was not the starting point: We tried to apply transparency to
generated mesh surfaces. The transparent objects appeared very often
rippled depending on the isosurface value chosen (For this I have still to
generate a handy example.)
I am leaving now into weekend, thank you again,
Regards
