Ah, mustn't neglect the blog.

David and I visited the VR lab at ACAD together last week, where we found to our relief that my webcam is supported without the driver disc (which I had forgotten). In fact, since our tour of the facilities with Alan Dunning, the lab has been equipped with its own (face-tracking!) webcam, and also ample USB extension cords which we will definitely be needing if we place the camera in front of the participants. David may wish to say more about this experience, but basically it was an important and somewhat painful first step where we familiarized ourselves with the equiptment and tried to get each thing working independently -- with middling success. One thing we have yet to determine is whether it will be possible to use infrared illumination with the webcam -- we tried using the IR lights in the lab, but it seems that at least those frequencies are blocked by both cameras.

So far I've gotten Python OpenGL rendering working on a linux platform, and python networking (server/client) betweem remote machines. Python is a fine programming system and I've no regrets about abandoning initial Java plans in favour of it! Also, Chromium is written in python which should make our interactions with it that much easier. Chromium is a system for distributed rendering on multiple workstations, capable of targeting multiple displays or projectors. This site also refers to a SIGGRAPH paper which should be in our reading list; Figure 2 illustrates the configuration appropriate for our system.

We aim to have the basic system (I hope David will post the image of our system diagram from his MADT proposal), sans any sophistocated multi-agent ecosystem, functioning before we adjourn for Christmas break.
