Want to plot a surface, graph of f[x, y], and then, on the surface,
draw:
(1) at the actual z-height, the contour curve for that height; and/or
(2) at the actual value x = x0, draw on the curve the section
("slice") of the curve f[x0, y] (and similarly for fixing y = y0).
I know how to do all that, I think. But I want the result to look just
right. To do that, the curves have to be a different color, or possibly
thicker, but -- most important -- be displaced a bit from the actual
surface so as to be distinctly visible.
Somewhere -- in this newsgroup, on the Wolfram web site, in a
Mathematica book, or in one of journals (Mathematica in Research and
Education, The Mathematica Journal) -- I once saw a very cleanly done
implementation that produces very nice results.
Can anyone supply a pointer to that?
