==Cave Availability== Check the tour/demo schedule [http://reservations.calit2.net/BrowseForSpace.aspx here] ==Starting Joystick== * Joystick is plugged into USB port. * Open Terminal window. Note: CalVR and VRPN for joystick tracking will be run in separate terminal windows. * Navigate to directory containing Joystick tracking executable. <br> <code> cd /home/neuro/CalVR/bin </code> * The "vrpn.xml" configuration file should already be in this directory, but if not, the most up to date file location is: "/home/neuro/CalVR/applications/vrpn_libusb_general/vrpn.xml" * Type the following command into the terminal <br><code> ./libusb_general_server </code> * There are a few possible ways that this command may not run properly. ** If the output from the terminal indicates that the "vrpn.xml" configuration file was not found, use the following command: <br><code> ./libusb_general_server XXX </code><br>Where "XXX" is the absolute path to the "vrpn.xml" configuration file. ** If the terminal output indicates that: <br><code>libusb couldn't open USB device /dev/bus/usb/XXX/XXX</code><br> There are two solutions: *** Run the previous command again as a <code>sudo</code> command.<br><code> sudo ./libusb_general_server </code> *** Modify permissions of the USB joystick. <code> sudo chmod a+rw /dev/bus/usb/XXX/XXX </code> and run the previous command again. *** Note: Both solutions require sudo privileges. If you do not have sudo privileges, have a user that does and run the second command to modify the permissions of the USB device. ==Troubleshooting== * To confirm that the Joystick is plugged in to the head node, open a terminal and type in the command lsusb and hit enter. You should see Logitech, Inc. ATK3 (Attack III Joystick) among the listed USB devices. * if a node hangs on a black screen after exiting CalVR, run tentakel killall -9 CalVR ==Starting OpenAL Audio Server for NexCave== * VNC into Server (IP: 137.110.116.10) Note: This currently does not work. Either a separate VNC server needs to be installed or the Mac installed VNC server needs to add a user for linux VNC connections. * Start Jack Router. ** Launch the Jack Pilot app. ** Click start. * Launch OAS. ** Open a terminal. ** Type: <code> cd OAS/Open-Audio-Server/server/build/bin </code><br> Then: <code> ./OAS oas_config.xml </code> * Note: If VNC does not work, access the server from its physical location in the server room (1608 B). ==Projects== * [[WaterMaze]]
