Theatre C Projection

http://www.ch.ic.ac.uk/theatrec/

Quick Reference Guide


  1. Mono or Stereo Projection mode (built in computer, Input 1, Projector 230 and/or 231)
  2. Laptop mode (mono only, Input 2, Projector 230)
  3. Resolution of 1280 by 1024, running at 75 Hz.
  4. Lectern unit: Planar stereoscopic LCD display, comprising two flat panels oriented at 90° to each other, with a semi-reflective mirror in between. Polarized glasses should be worn to view the stereo operation. To operate as a conventional mono LCD, move the reflective mirror up into the park position, and there will be no need to wear the glasses.
  5. System installed by Inition Ltd., May 2006.


Power On Cycle

Can be done either with the remote units, or below online using the computer. An operating manual for the remotes is available here. The Model type is EWiki LC-X50M.

  1. Login in using your regular College login and password.
  2. A program called NetControl needs to be run. An icon should be on the desktop, but if you cannot find this, use Programs => QuickLogix => Netcontrol => Netcontrol
  3. From the initial panel that appears Select Network, then Search from the panel that appears.
  4. Two devices should appear in this display. Projector 226.230 is in fact the bottom unit, and 226.231 is the top unit. If you want to project a laptop, make sure that unit 230 ONLY is switched on.
  1. Highlight one projector (230 for laptops) and Select IP.
  2. In the main panel, the connect button now becomes available. Before doing so, select the Projector model as EIKI LC-X50M, and then press Connect (click here for air filter cleaning and lamp replacements)
  3. Next select Status and Get Status from the panel that appears.
  1. To switch a projector on, select Control and from that panel, Power On. The status display, when updated, will reflect the power on cycle (about 2 minutes). The display also reflects the Lamp time. We expect perhaps 4000 hours of life (The lamp intensity is currently set to Economode. If anyone really want a brighter screen, you can increase the intensity to full).
  2. If for some reason the computer power on cycles does not work, then Remote control units (one per projector) are available. They are normally held by Pete Sulsh. One press of the red button to switch on, two is to switch off. They are not left in the theatre to avoid "evaporation".
  3. There should not be any normal need to adjust the projector settings, but one artefact which can happen is that the image can dislocate off the screen by about 15 cm. To correct this, select the topmenu item from the Control panel. A menu appears on the projected screen. Select the red right arrow from the Control panel until an item called PC Adjust appears on the projected screen. Now press the yellow "sun" on the Control panel to select this item. It will take about 5 seconds, after which the displayed image should again be centered onto the projector screen. Press the second Menu item to remove the menu display from the projected image.

STEREO Mode.

  1. If you want to work in stereo, you will now have to repeat the above cycle for the second projector. But first, you have to disconnect from the first one and then repeat 4-8 above for the second projector. At this stage both projectors should be on.
  2. You will need to put on a pair of stereo-glasses. These are normally held with Pete Sulsh, and with the Faculty IT support team in room 134. These will normally be issued at the start of a lecture, and collected by the organiser at the end of the lecture. Some people may feel a little nauseous when the stereo-projection commences. It takes the brain a few seconds to accommodate, and the odd feeling passes quite quickly if it occurs at all. If the odd feeling persists, close your eyes and just listen!
  3. To project in stereo you will have to use a stereo-enabled program. The best for molecular projection is DS Viewer Pro, an icon for which should be on the Desktop (or via Programs/Accelrys DS ViewerPro 6.0/DS ViewerPro 6.0). From the File/Open menu of this program, navigate to a molecule file (the default navigation is to an examples folder). Most 3D molecule file types are supported by the program. Sources for 3D molecule coordinates are most often either the Cambridge Crystallographic database (you can save as a CIF and open this in DS Viewer directly) or from molecular modelling calculations.

  1. After (not before) you have loaded the molecule, the Stereo mode has to be switched on. You may wish to then optimise the stereo effect by going to View/Options, and tweaking the Stereo/Separation (recommended 4) and Skew settings (recommended 5). To save these settings, you will have to save the molecule file.

  1. It is possible that the New Stereo 3D Window option in the Window menu of DS Viewer Pro may be grayed out, in which case Stereo display will not be enabled. To re-enable it, go to the "system tray" in the toolbar at the bottom of the screen, and open up by right-clicking the nView Desktop manager. From nView display settings, ensure that Clone is enabled, rather than Single Display (this latter mode is unfortunately a side effect of connecting to the computer using Remote Desktop, which sets Single Display mode and does not reset it to Clone mode when finished).

Other Programs.

A number of other programs on the desktop computer are Stereo-enabled, including Express Stereo Demos, QuadroView, StereoSlides, Stereoscopic Player etc. These programs can play a variety of types of media, including DVD movies, 3D Photographs, VRML files and others.
  1. StereoMovie Player will play any .avi or .svi file in stereo
  2. QuadroView will play .wrl files in stereo. Remember to hit the switch to stereo button in Quadroview.

Powering Down

The projectors will power down themselves if no video signal is received from a computer (i.e. its been switched off) after ten minutes. It is also possible to power down from the Control menu of the Netcontrol program by selecting Power Off. The Status display should reveal this happening. Follow the procedure above to change projector, and shut the second projector down as well (assuming it was on).
