X-Core is a collection of programs to help integrate marine geologic data with OpenInventor and the Web. It integrates data from core photos, paleomagnetic studies, microscopic photos, seismics and multibeam bathymetry with an OpenInventor viewer. The scene models then have hyper links to addition scenes and to traditional 2D web data bases. This software is available under the GNU Public License. © 2004 Kurt Schwehr
