The code in unsupported/isogeometry is a "fork" of JTS ... why you ask? JTS is an implementation of the Simple Feature for SQL definition of Geometry unsupported/isogeometry is an implementation of the ISO 19107 definition of Geometry
Why do we need two definitions? The JTS one is focused on a "flat world" geometry; everything is straight lines on a plane. The ISO 19107 definition is more complicated (curves on a sphere, 3d structures, etc...). For now (ie the next couple of years) use JTS; and help round up funds/volunteers for the ISO19107 work.
