The ISU press release does not mention it, but the new C6 will be driven by open source technologies such as VR Juggler, OpenSG, and of course, Linux.

Does Hewlett-Packard actually make GPUs? I would think they would go with some off the shelf chips from Nvidia or ATI, surely those can push more pixels than anything else and they would have the advantage of a relatively standard API (opengl for example). Is there some very specialised requirement I'm not seeing here?

I can only comment about the API - we're using something that is a standard (for us) and that fills in as nice middleware: VRJuggler. It sits atop (among other things) OpenGL.

The Virtual Reality Application Center at Iowa State University is kind of a testbed for open source, being used as a trial to see if this type of development can really work.

Our largest project, VRJuggler, is a development environment for virtual reality apps and is absolutely open sourced.

We've had great success using the open source academic model, particularly in getting interest and support for the project from people outside the university.

Are there any other labs out in academia that are also promoting the use of open source?

And we musn't forget about Iowa State University's free (LGPL'd) software for developing immersive environments, VR Juggler.

The "VRAC team" is actually about 150 people. the VR Juggler team (the one that writes the software that runs the C6, and many other VR devices), is actually about 4 grad students (allen,chris,patrick,kevin), the original inventor of the CAVE (Dr. Cruz-Neira), and a few others...

VR Juggler is an opensource virtual reality platform. It is the next generation of CAVE software. It runs caves, c6, HMD, powerwall, desktop VR, etc... highly configurable and highly extensible.

For background info: Dr. Cruz wrote the original CAVElib (closed source) at EVL for the original CAVE system she designed. NOTE: that all CAVE(tm) systems are only 4 walls! The C6 at VRAC is the worlds first 6 sided cave-like device.

VR Juggler is her next endeavor, it doesn't suffer from the problems that CAVElib does, and whats best is that VRJuggler is completely open source (LGPL).
