Comment(by wcauchois):
Here's an implementation of region_function that simply removes all faces
which do not satisfy the predicate. It looks pretty bad unless you use a
high plot resolution, but it works!
Yesterday William brought to light some issues that made me realize the
task of creating a better looking region_function is frought with some
subtlety. Since region_function can be any Python callable, we cannot make
any assumptions -- it could, for example, return a random boolean.
However, I would like to implement some kind of heuristic that at least
smooths the edges around the excluded region. In any case, we are not
really responsible for the accuracy of the region beyond the plotting
resolution.
Cheers,
Bill
