Difference: IzabelleJanzen (2 vs. 3)

Before working with the cyvis box you should turn on all the projectors (simply use the remote, point it at a projector and hit power). Not all the projectors will turn on, as several are burnt out and not replaceable.

For different viewing conditions the cyvis box needs to be reconfigured. Specifically, if you want to switch between 2D and 3D viewing or turn off the automatic blending of the overlap between the projectors. These configurations are packed into pre-existing scripts the set all configuration parameters needed for specific types of viewing. These scripts are saved into the cyvis directory of the repo.

To run one of these scripts, you need to connect to the cyvis box over the serial cord. The lab has serial to USB adapters sitting around, use these to simply plug the serial cord into a usb port.

Then go to device manager and look up the name of the USB port you plugged it into. For example, if nothing has changed, the serial adapter is plugged into com3.

Now we can run the scripts. Included in the cyvis directory is an executable called hyperterminal. This is essentially a telnet client to connect over the serial port. You should connect using the port you looked up in the device manager, and the bit rate should be 38k (if you don't have the correct bitrate, the character set will look wrong when you type).

Note, by default it doesn't actually show what you typed in the console. Look for the configuration option in hyperterminal "duplicate key presses locally...." and turn it on.

To run a configuration script click transfer->send text file and select the script you wish to run. This essentially copies and runs each command in the cyvis configuration script, and should take several minutes to run.

Now you can connect the two DVI cables to your computer (unplug the VGA cables to your desktop first!). If everything worked properly, you will see the screen as two separate monitors (one representing the right eye, and one the left eye).

Note The cyvis box is somewhat finiky, and often the projectors or images won't show up properly.

If you only see one monitor, Right click->screen resolution-> detect may allow you to detect the other one.

also, restarting the cyvis box, or changing back to mono no blending, then changing to your desired setting while the projectors are on often helps.

If nothing is working, try checking the input source for the projector matrix. If you look at the front of the cyvis box you will see a series of blue lights representing groups of 4 projectors. They should all be on input channel 1. There is a remote sitting on top of the cyvis box to change these.

Also, make sure SLI (dual video card support is on). You can change this setting in nvidia control panel-> SLI->maximize performance.

If you notice the images appear upside down or otherwise distorted, you may need to change individual projector configuration. The remotes aren't precise enough to really due this, so unfortunately you will have to go behind the screen and physically hit the menu buttons. You should see in settings->screens options for rear projection and ceiling mode. All projectors should be on rear projection mode, and SOME should be on ceiling mode. Ceiling mode is for any projector that is mounted upside down (IE from the ceiling) right now this should be on for all projectors, except the middle row, which is mounted normally.

In order to run the experiment from scratch, you will need the following:

-HASP usb key. This should be in the supplies box and contains the licence to run the vicon software. -The vicon cameras -The vicon datastation box -The generic ethernet crossover cable -The calibrating wand (it has 3 reflective balls) -The head tracker with 3 markers -The vicon connecting cables, splitter boxes and tripods
