I've been using DelaunayWatson( set of two dimensional vertices) quite
effectively for awhile. However just recently I found a case it's failing
on. The data is not fundamentally different (at least in any way obvious
to me) for this failing case, so I'm wondering what's going on. Attached
is the list of x y points. There are no duplicates. The failure message
doesn't help too much, just
visad.SetException: Delaunay.finish_triang: error in triangulation!
at visad.Delaunay.finish_triang(Delaunay.java:592)
at visad.DelaunayWatson.<init>(DelaunayWatson.java:318)
Any ideas?
BTW "jiggling" the points is really not an option for me, as for other
reasons I need them to be their original values. I'd rather remove
offending points than change any.
