VMD-L Mailing List

We compiled and run VMD with CAVELib on LINUX pc with RAVE (Fakespace), but have
a problem with .vmdsensors file. The only example we have is:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
###
### Configuration for the NCSA CAVE trackers
### http://www.ncsa.uiuc.edu/Vis/Facilities/
###
device cavetracker cavetracker://local/cave
scale 1.0
offset 0.9 -4.0 -1.0
device cavebuttons cavebuttons://local/cave:0,1,2,3
# For left-handers
#device left_handed_cavebuttons cavebuttons://local/cave:2,1,0
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Since http://www.ncsa.uiuc.edu/Vis/Facilities/ does not work any more I could
not find any information regarding "//local/cave" variable.
How it is defined?

This is what we have:
1). trackd reads two FOB sensors and Work wand connected to the LINUX box via
serial port using the following trackd.conf:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

# Define Flock of Birds

ConnectorOption controllerSHM4127 numValuators 1 2

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

and our_hostname.conf has lines:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
....
# Type of tracking and input (daemon or simulator)
TrackerType daemon
ControllerType daemon
Simulator n
Trackerdaemonkey 4126
Controllerdaemonkey 4127
# Run tracking in serial or parallel
SerialTracking y
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2) .vmdrc has lines:
tool create grab ravetracker2 ravebuttons1
tool scale 1.9 0
tool offset -1.33 -0.1 -0.7 0

3) .vmdsensors has lines: (which do not work:( )
device ravetracker2 cavetracker://localhost/RAVEFlock:1
device ravebuttons1 cavebuttons://localhost/RAVEWorkWand:0

Please, let me know if you need more info from me or have any idea how to
declare our devices in .vmdsensors the way VMD can recognize them.

Sincerely,
