Vincent:
Thank you very much for your time to answer my question
about our ACITC floor plan for the Visualization and
Animation Laboratory. I will pass on your recommendation
to my colleagues here at Virginia Tech. If you are
interested in reviewing our progress on the design of our
lab, our plans can be viewed at ...
http://www.sv.vt.edu/future/vt-cave/VT/acitc.html .
For the last 6 years Virginia Tech has enjoyed our
partnership with NCSA and now most recently as CAVE partners
and the NCSA-SGI Power Grid Alliance members. I hope that
this relationship will also continue under NSF-PACI.
We look forward to the day we can return the favor, but for
now we very much thank you for helping us get started.
Please send my regards to Tom, Bill and John.

Bill asked me to get you the iwall dimensions, since he's away for awhile.
First, some comments on the lab layout you have online.
Iwall room:
Leave room for a small rack of electronics like audio mixer, tracker
gear, wand pc, rgb router or patch bay, vhs vcr, dvc vcr, betacam vcr, etc.
This is best put right up front next to the wall.
You may also have many requests for PC and Mac presentations on Wall. Good
to have permanent ones in the room, hooked into rgb router.
Cave room:
Regarding the idea of a separate control room: Users like to have the
main console(s) right near the mouth of the cave, as they may be walking
back and forth, or controlling something from keyboard and need to look in
cave, or want to hear sounds from audio system.
Console user may be talking actively with people in cave.
Demoers need to walk to console often.
Be careful of the lighting in the "observatory". Don't want it to spill
into cave area.
Careful what large electrical/magnetic things are next door or above any
trackers, so as not to interfere.
IWall dimensions
Our screen is 142" wide by 107" tall. This includes 1.5" aluminum frame all
around, so image area is smaller. Screen size was dictated by height of our
ceiling. Make as big as you like, but not too big that screen brightness
is diminished.
At that size, projectors are placed 102" away from screen. That is the
front of the lens. This gave good range on the projector "size" adjusters
to make image 1/4 of the screen. Physical lens focused there too. (may not
focus if any closer though.)
Scaffolding holding the projectors:
Overall 120" wide, 73" tall, 37" deep. Plus the feet stick out about 5".
The shelves are 16" and 64" off the ground.
The front of the scaffolding is even with front of lenses. The back of
scaffolding is about 140" from screen.
You saw where the tracker transmitter box was. About 6' from screen, and
low. Too low for my tastes, but you have to think about range of
transmitter.
Let me know if you'd like anything else.
