Yep, looks like a bug. Martin Davis will want to look at this, but he's away until Monday.

Subject: [jts_discussion] Difference Problems.


Hi, all,

I have two geometries, and I want to do a difference on these two
polygons.

If I run it against "JTS test builder", it is ok and gives me back
correct result.

However , if I run it in my code.

do something like this:
Geometry geomDiffWKT1=3Dnew WKTReader().read("MULTIPOLYGON
(((1665830.62....)))")

Geometry geomDiffWKT2=3Dnew WKTReader().read("MULTIPOLYGON
(((1668033.7441322226 ....)))").

It gives me a "no outgoing dirEdge found" exception.

Any idea..

Thanks,

J.W.
