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

Nexus is an experiment with Semantic Web RDF data visualized in three dimensiodians that can be done collaboratively amongst many people (and concurrently) at disparate locations.  Nexus also acts as a platform to try out various design ideas, technologies, and methodologies.  The original Nexus

The other year, I developed a molecular visualization system inside of Second Life (see http://www.ebremer.com/monolith) with a demonstration video of it in operation on YouTube for purposes of learning the scripting language LSL of Second Life and for the fact that I found the concept of a 3D collaborative visualization environment with

The trouble with triples (not tribbles ;-), for me, is that there are alot of them.

Here is an image (click on image for larger image) of a model I did earlier with Nexus in Second Life using Tim Berner-Lee and James Hendler's FOAF data linked and visualized in 3D within OpenSimulator with Nexus.  The only code change needed port it over to OpenSimulator from Second Life was the removal of the warppos fu

OpenSimulator is a open-source version of Second Life's server software that emulates much of Second Life's functionality and in some ways, goes beyond it.  Earlier this year, I moth-balled my Monolith project in favor of my Nexus project - it's semantic replacement and then some.  But I decided to vi
