The 3D algorithm depends quite a bit on the CAD structures used in Gmsh,
so it will probably take some work to extract a stand alone version. But
feel free to do so, of course. You can use the code any way you want, as
long as you comply with the terms of the GNU General Public license.

Have a look at tetgen: http://tetgen.berlios.de/

Best,
