Hello,
As a first pass, just surround the evaluation with a try/except, as
you would in Python. Perhaps you could set the value in the except
clause to nan.
For the 2d-plot, I test if a result is a real number by theses tests :
#
# The real number without infty nor NaN=NotANumber
Would all these ideas for testing deal with the triangulation issue,
Bill? Your original post seems to imply this.

I thought that, during triangulation, we could test for NaN values and
delete those faces.

I thought that, during
relatively simple, but when you remove a point in a 3D plot you could
be affecting several faces. There is also the matter that evaluation
is separate from triangulation, so you have to find out how to
communicate the fact that a vertex doesn't exist between the two
stages (since

I was looking into this issue this afternoon, and its more complicated
than it might appear at first. Removing a point in a 2D plot is
relatively simple, but when you remove a point in a 3D plot you could
