I did a little hunting and found the main website for Rome Reborn 1.0, at the Institute for Advanced Technology in the Humanities at the University of Virginia. Here is a blurb from the website about the history of Rome Reborn:
"From 1997 to 2007 the UCLA Cultural Virtual Reality Laboratory (CVRLab), the UCLA Experiential Technology Center (ECT), the Reverse Ingineering (INDACO) Lab at the Politecnico de Milano, and the Institute for Advanced Technology in the Humanities (IATH) of the University of Virginia collaborated on a project to crate a digital model of ancient Rome as it appeared in late antiquity...."
