Re: [PyMOL] Monitors for molecular Modelling (Stereo 3D LCDs)

[Joachim Reichelt]

I just installed the NVIDIA GLX Module  185.19  Sat Apr  4 07:32:28 PST 2009 (beta) driver on Linux and found in the README.txt: Option "Stereo" "integer"     Enable offering of quad-buffered stereo visuals on Quadro. Integer     indicates the type of stereo equipment being used:         Value             Equipment         --------------    ---------------------------------------------------         1                 DDC glasses. The sync signal is sent to the                           glasses via the DDC signal to the monitor. These                           usually involve a passthrough cable between the                           monitor and the graphics card. This mode is not                           available on G8xGL and higher GPUs.         2                 "Blueline" glasses. These usually involve a                           passthrough cable between the monitor and graphics                           card. The glasses know which eye to display based                           on the length of a blue line visible at the bottom                           of the screen. When in this mode, the root window                           dimensions are one pixel shorter in the Y                           dimension than requested. This mode does not work                           with virtual root window sizes larger than the                           visible root window size (desktop panning). This                           mode is not available on G8xGL and higher GPUs.         3                 Onboard stereo support. This is usually only found                           on professional cards. The glasses connect via a                           DIN connector on the back of the graphics card.         4                 TwinView clone mode stereo (also known as                           "passive" stereo). On graphics cards that support                           TwinView, the left eye is displayed on the first                           display, and the right eye is displayed on the                           second display. This is normally used in                           conjunction with special projectors to produce 2                           polarized images which are then viewed with                           polarized glasses. To use this stereo mode, you                           must also configure TwinView in clone mode with                           the same resolution, panning offset, and panning                           domains on each display.         5                 Vertical interlaced stereo mode, for use with                           SeeReal Stereo Digital Flat Panels.         6                 Color interleaved stereo mode, for use with                           Sharp3D Stereo Digital Flat Panels.         7                 Horizontal interlaced stereo mode, for use with                           Arisawa, Hyundai, Zalman, Pavione, and Miracube                           Digital Flat Panels.

In their own words: "I do not know the exact release date however it should be around the same time as when new QuadroFX drivers based on the Release 185 driver branch is available in the near future..."

Resolution is 1680x1050, which is the most common with computer flat screens (better forget 1280x1024)... It sells for ?300 in France right now. 2x60 Hz stereoscopic glasses can be bought separately from nVidia ($200, or $600 bundled with the Samsung monitor). They are especially interesting as the stereo support is done at the drivers level. http://www.nvidia.com/object/GeForce_3D_Vision_Main.html For the moment, unfortunately, the stereo drivers are only available for mainstream GeForce cards under Windows Vista, but it should not take long before nVidia provides Linux drivers. Support for the Quadro range was announced for spring 2009, this might be done at the same time. The glasses are also compatible with any CRT monitor capable of >= 100 Hz - so the old 21" >30kg CRT monsters from Mitsubishi/Sony/Illyama, which can be found 2nd hand for about nothing, are interesting. This is good to know if you want to stick to 1280x1024, as LCD panels perform very poorly when not set to the native resolution. Bear in mind that stereo with CRTs is quite painful to the eyes, the new Samsung LCD might be significantly more confortable to work with...

VCH was I think the marketting arm of the German Chemical Society, but was aquired by Wiley some time between 1993 and 2003 (my vagueness here is because I am looking at the imprints of books published on these dates). Whether Wiley are still selling the viewers is another matter. There were two models (I got both of them when the Royal Society of Chemistry was selling them). With regard to monitors, Mitsubishi-Electric advertised their Diamond 1080p DLP HDTV as being capable of stereo viewing using shutter glasses. It came in three models 57, 65 and 73 inches. They have sockets for connection to computers, and resolutions up to 1280 x 1024 and 1920 x 1080. I do not know how much they cost. They were announced in North America, and I recollect that MItsubishi in the UK had no record of them I have always thought that using twin projectors was a better solution for viewing stereo when more than one person is involved. But projectors with native resolution of 1280 x 1024 (which I regard as a standard) are rather rare.
