Jaco,
I tried the shade_surf, but only before the 2d plot, which
results in "transparency" ---- doing it after works, but not
perfectly. Looks kindof shady. Heh heh. I think I'm going to
make a separate graph, though the editor will have a fit. I
am trying to jam too much in one graph, I think... Thanks for
the help.
Liam,
Thanks for that URL. Interesting stuff.
Cheers,
Andrew

Drawing a wire mesh is not supposed to have an opaque
effect, I suppose... I haven't tried, but SHADE_SURF should
do the trick, with the keyword SHADES set to an array of
!p.background (so that it just erases, without light source
shading).
So first set up the transform, then do your plot on the wall, then
erase the surface, then draw a wire mesh again.
No doubt you will run into yet another problem, but it should be
fun. I find it hard to believe, though, that all this will lead to a plot of
outstanding clarity... :-)
