I think that parametric plot could work in this simple example.
r,phi,y=var('r phi y')
A=parametric_plot3d([r*cos(phi)+2,r*sin(phi)+3,(r*cos(phi)+2)^2+(r*sin
(phi)+3)^2],(r,0,2),(phi,0,2*pi),opacity=0.9)
B=parametric_plot3d([r*cos(phi)+2,r*sin(phi)+3,0],(r,0,2),(phi,
0,2*pi),rgbcolor='red')

Robert and Jason,
1. Thanks for the ideas and suggestions. I can probably do something
useful with Robert's parametric plot suggestion for the moment.
2. Yes, Jason, Mathematica's RegionFunction is exactly what I had in
mind and would be an extremely useful addition to plot3d(). But I
know n

Still thinking on this problem. Trying to plot a function which is

Hello,
William forwarded this thread to me. I've been working on the
parametric_plot3d code under his guidance, and I think I could
implement this feature, the option to specify points for exclusion
from a plot. Last night I investigated an implementation that simply
removes all faces whose verti
Bill,
Thanks for working on this! I realized today that such a feature will
be indispensable when I start talking about multiple integrals in
class. I'd be happy to test out anything you get working.

Ooops. ;-)
Took Robert's work with cylindrical coordinates and shamelessly
adapted it for class in the morning. Robert's example verbatim, then
a second example with a function from the textbook having a min and a
saddle point. Placed a circle in the domain in bet
