JTS didn't support 3d when I added it to GEOS, so can't really serve as a source of information. The 3d task was added driven by customer needs, so the only working and tested functions was the one the customer needed. If I recall correctly it was mainly Intersection and probably Union. Since other functions are based on the former, there may be side-effects you wouldn't care about if you aren't using 3d features. Paul draw the specs about expected behaviour. Dunno if there's a doc around and I likely lost mine (Oops). --strk; Free GIS & Flash consultant/developer () ASCII Ribbon Campaign http://foo.keybit.net/~strk/services.html /\ Keep it simple! _______________________________________________ geos-devel mailing list geos-devel@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/geos-devel
