How to set up a Fish Tank VR system.1. How do I setup a Fish Tank system similar to the one you have in the gfx lab at Brown?
- This is a help document to set up a fishtank system similar
to the one we have in the gfx lab and run the brain application.

HARDWARE / OS
- make sure you're running windows XP (2k or even 98 may work, but XP
is probably best to stay consistent.)
- you'll need a stereo capable graphics card (ATI FireGL 2),
FastTrak tracker, emitter, and stereo glasses
(http://www.i-glasses.com/Store/3dpcinternet.php3 A103614 PC Gaming
System (Cordless)). Alternatively, you can use NuVision's
60GX (www.nuvision3d.com) stereo glasses that are more ergonomic and
apparently have larger lens viewing area.
- plug VESA-3 standard cable (attached to IR emitter) into back of gfx
card (you will not need any of the adapters unless you are using the
- put emitter on top of monitor
- turn glasses on with small button above left eye
STEREO (details completely depend on which gfx card)
- get FireGL card into machine
- download driver and install (enough detail?)
- run supplied graphics program to make sure it's working
- right click on desktop, goto properties, goto settings, goto
advanced, find a tab that says something about "GL", check the enable
"quad-buffered stereo" box
- run supplied stereo demo program to make sure it's working
- attach fasttrack hardware to COM1 serial port
* if the mouse starts jumping all over the screen, boot computer with
polhemus turned off and unplugged from the serial port, then when done
with the boot, connect to serial port and turn it on
- run polhemus-supplied airplane demo program to make sure it's
bdif: DT-MRI Brain Visualization Application.
- Extract 'bdif.tar.gz' in a directory. If you have
cygwin installed on your pc, you can extract it
entering the following from the cygwin command line.
'gunzip < bdif.tar.gz | tar xvf - '
PowerArchiver 6.1 (freeware) or Winzip (commercial) would also
do the same job.
- Replace the word 'tuna' with the name of your computer
in the file 'share/vrpn/bin/vrpn_cs_tuna.cfg'.
- run 'share/vrpn/bin/vrpn_server.bat' (vrpn server)
- run one of 'share/bdifglue/bin/bdif_*.bat' files each of which
represents a different brain data-set.
- G, H rotate the brain around y(vertical) axis
- J, K move 2D slices in either direction
- F cycles through between the three orthogonal slice orientations
- S switch to stereo mode (default)
- M switch to mono mode
- T start tracking (default)
- R stop tracking
- N bring the command line menu (use <alt-tab> to switch to the command
- UP, DOWN move the brain up and down.
