NAME: How to set up a Fish Tank VR system. QUESTION: 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.

Alternatively, you can use NuVision's 60GX (www.nuvision3d.com) stereo glasses that are more ergonomic and apparently have larger lens viewing area. GLASSES * 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 GeForce3 card) * put emitter on top of monitor * turn glasses on with small button above left eye STEREO (details completely depend on which gfx card) o get FireGL card into machine o download driver and install (enough detail?) o run supplied graphics program to make sure it's working o 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 o run supplied stereo demo program to make sure it's working TRACKING o 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 o run polhemus-supplied airplane demo program to make sure it's working DEMO bdif: DT-MRI Brain Visualization Application. Install: - 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: - 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. Use: Keyboard:: - 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 to switch to the command prompt) - UP, DOWN move the brain up and down.
