From the beginning, I wanted Nexus to be a collaborative visualization system allowing multiple clients in multiple locations to see the same visualizations in real-time.  The issue that arises here is knowing "where" in the 3D semantic web visualization the other clients (people/avatars) are and what direction they are looking at.  In the 3D digital world, you have the concept of a "camera".  This is essentially your point-of-view in a particular 3D simulation.  As the camera moves, your view of the model changes as well.  In order to know where the other clients are in the simulation

It took less time than I thought it would, but here is an updated version of the 3D FOAF graph from my last posting with node sizes determined by the log base 10 of the number of links into a particular node.  The coulombs law for the larger nodes is adjusted so that larger nodes "push" out harder to accomodate the larg
