The omnidirectional treadmill (ODT) is a cool concept. Many connected belts rotate in one direction, then the whole set rotates in the perpendicular direction. This gives users the ability to walk in any direction. It was invented by Virtual Space Devices.
DISOLISS was my full time project at University of Lousiana at Lafayette. We collaborated with the Army Research Laboratory's Human Research and Engineering Directorate (HRED) to develop a distributed simulation framework for dismounted soldier cognitive research, in CAVE-like environments with omnidirectional treadmills interconnected together. University of Louisiana at Lafayette was the first non-military institution to have an ODT! We officially inaugurated it during IEEE VR 2009, which we organized and hosted in March 2009.
I was in charge of programming the event management, collaborative session and physics modules. The immersive application is programmed with VRJuggler, using OpenSG as the renderer. It runs on a graphics cluster, so part of my responsibilities was the data synchronization. The system integrates the IEEE Distributed Interactive Simulation protocol. And Bullet is the physics engine.

Open-DIS is an open source implementation of the DIS protocol. Its nicest feature is the code generation of DIS Pdus from XML files, which avoids having to manually write the classes for each message. I needed to add the Live Entity family which was not originally implemented, and all I had to do was modify the XML describing the protocol.
I have contributed the implementation of C++ DIS Enumerations back to the open-DIS developers.

- DM6111 - GENGA: Games engine architecture [specialist diploma] (Jan-Feb 2007)
Second Life® at NYP
Because my research area has been collaborative virtual reality, one of my main focuses as a lecturer was work on 3D worlds for games education and development, with Second Life® as the platform. My SL avatar's name is Chica Digital.
Final year projects (FYPJ) using Second Life
12-week projects developed for industry clients. I was the technical supervisor for development teams consisting of senior design and programming students.
Latest projects (Sep-Nov 2007):
- Showcase island for a Singapore government body
- Interactive island for a private corporation
- Customization of the interface and 3D interaction of the open source viewer
