i didn't know that there still exist so many CAVE_people in this technology
age :)
and thanks for all the response
for those interested in performer/CAVELib examples (i certainly am)
i have been guided to the following URL by:
Bill Sherman: http://www.freevr.org/
Brian Corrie: http://www.evl.uic.edu/pape/CAVE/prog/examples/
ok, we have a curved (150 degree, 3 screen) display setup, sgi powered
i have my scene application written in Performer,
i rewrote a small library using performer to handle stereo display.
then i changed it so that CAVELib would handle the stereo display
instead of me doing it manually through performer,
and input is via keyboard/mouse.
now, i am phasing out keyboard and mouse input to replace
it with headsensor, wand and spaceball via trackd.
yesterday i was working on a simple config script file for trackd &
trackdserver to read a head_track_sensor
with trackd/trackdserver running on the same machine.
but i still can't seem to access the data, moving the sensor does not change
coordinate value printout.
is the problem with the script file?
-------------------- trackdserver.conf -----------------------------

thanks again

Hi Tien,
Are you trying to use the pfCAVELib? Or are you trying to run a CAVE simply
with Performer? If you're using the pfCAVELib it handles talking to the
trackd and then there are CAVEGet functions for accessing any of the sensors
positions or orientations. If you're trying to use Performer only, you'll
need the trackdAPI to access the trackd data from shared memory. If you send
more information we can try and help.
Matt

hi,
are there any CAVE_people out there? :)
i am trying to get my performer program to work inside
CAVE with input devices running from trackd
i can't seem to find any good examples which links these together
CAVE_people...you know where i can get access to these type of examples?
if not, then just config file for trackd & trackdserver
which designed for one WAND input?
many thanks in advance
cheers
tien
