Oh, good lord, no! Please use JTS, a mature library for your needs. The plugin/geometry module is pioneering/experimental work and will not work correctly. It will move to unsuppported/ as soon as I take the hour or two to make sure that's done right. Plugin/geometry was pioneering work. Unfortunately, they set out with the idea in mind "the hard thing is 3D" when my read of the spec is more "the hard things are allowing for different implementations of ISO geometry, i.e. implementations which want different rules for boundary intersections, correctly handling geometry CRS's, dealing with curved geometries which violate the core assumptions of JTS, and only then 3D". I'm only now just starting to come to grips with *what* needs to be designed in the library, next is *how*, then the actual design, and finally the coding. So today, go with JTS. cheers, adrian ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
