Re: [ccp4bb] Stereo solution with Nvidia '3D vision' or '3D vision pro'
Not only do you not need a high-end graphics card, you don't even need the proper graphics drivers installed. When I went to FC13 (upgrade from FC7, I don't know why), my quadro fx1400 was no longer supported. It would not work with hardware stereo (emitters/glasses of old). I went to Zalman monitors and all is great. Frankly, stereo is not needed as much in a nice bright LCD monitor (very crisp, looks great), but if you want it, Zalman is the way to go (passive stereo - light glasses, no hardware requirements beyond the monitor) Good luck Dave On 5/10/2011 12:27 AM, Duangrudee Tanramluk wrote: Dear Yu, The graphic card I am using is Nvidia Quadro FX580.

Re: [ccp4bb] Stereo solution with Nvidia '3D vision' or '3D vision pro'
Hi, I tried upgrading the driver yesterday to the 270.41.06 version but it didn't make any difference, still only 100 Hz. Are you using Windows or Linux? We're using the 64-bit Linux driver. We had the same problem initially with the Asus VG236 until we went into nvidia-settings and turned off Force Full GPU Scaling for the monitor under the GPU settings. Usually this option is unchecked for standard 60 - 75Hz LCDs but I found this was checked for some reason, unchecked it and then the monitor went blank momentarily and came back. Then the refresh rate increased from 99.99Hz to 119.98Hz. The information menu in the monitor itself also showed 120Hz. This has to be applied for every user or you can copy ~/.nvidia-settings.rc to other users' directories. The system is currently using the 260.19.26 linux 64 bit driver running CentOS5.

Re: [ccp4bb] Stereo solution with Nvidia '3D vision' or '3D vision pro'
Hi, Eric and Carsten, If you are using Linux try launching 'nvidia-settings' and disable GPU scaling. My system was RedHat5 64-bit. I set the option at that time, though I forgot to mention it… nvidia-settings stores the settings into ~/.nvidia-setting-rc, therefore it is not system-wide. I also annoyed that I should launch nvidia-settings when I login. Instead launching 'nvidia-settings', I set FlatPanelProperties in xorg.conf as below. Section Device Identifier Videocard0 Driver nvidia Option Stereo 10 Option FlatPanelProperties Scaling = Native EndSection Hope it helps.

For example, with the last version of the Nvidia driver I tested, the driver refused to put out an Nvidia 3D Vision sync signal (stereo 10 in xorg.conf) unless there was a 3D capable LCD attached. I don't know of any technical reason the Nvidia 3D Vision couldn't be used with a CRT but Nvidia has apparently chosen to disable it (or at least make it hard to enable) in the Linux driver. Going the other direction, using RealD with and LCD system, it might be possible but you probably have to match your RealD emitter with RealD glasses. Older CrystalEyes glasses (CE3 and earlier) generally do not work with LCD monitors because of the polarization in the glasses. We recently got some CE4 glasses and they don't seem to have that problem although in practice we are using them with a projector, not LCD monitors. But I don't really like the CE4's, there is too much of my field of vision under the glasses that they don't cover. We've observed some really weird configurations that appear to mostly work, such as plugging in a RealD emitter and glasses when the driver is configured to output a signal for Nvidia 3D Vision (stereo 10 option under Linux). You don't say whether you are using Windows or Linux and there may be variations in the drivers, variations by card, etc. Regarding card to card variations, we've observed 3D setups in conference rooms with multiple emitters where some Nvidia cards happily drive multiple emitters with particular splitters boosters, but other Nvidia cards don't. The bottom line is if you mix hardware you might have problems and vendors are unlikely to help you. If you have CE4 glasses already, you can try it with an LCD and it may work. Otherwise, if you have to buy new glasses (ie, you have CE3 or older), you might as well get the Nvidia package with the emitter included. 3D Vision Pro uses the 2.4 GHz band instead of IR to transmit the sync signal so if you were setting up a conference room in theory the Pro version might be less likely to leave dead zones in the conference room. For a single user workstation it's very unlikely that you would get any benefit. Just to muddy the waters a bit, I have not seen a working 120 Hz stereo setup working on the Acer GD235 monitor. We have a bunch of them set up, and we put a 120 Hz mode line in xorg.conf. If you ask X11 it says it's running at 120. But if you ask the Nvidia driver or the monitor, it reports 100 Hz instead, and visually there is enough flickering that the monitor and the driver seem to have the correct number. I'm curious if anyone else here has looked in detail to make sure their Acer-based system is running at 120 and found that it is actually doing what people claim it can do. I find the 100 Hz LCD flicker annoying over long periods so I am still a neanderthal CRT user. My coworkers were convinced their LCD systems were running at 120, when they were actually only running at 100. I'm not sure if this is a driver problem or a monitor problem. -Eric On May 6, 2011, at 11:27 AM, zhang yu wrote: Dear colleagues, Sorry to present the stereo issue to the board again.

Re: [ccp4bb] Stereo solution with Nvidia '3D vision' or '3D vision pro'
1. No you cannot use your old stereo emitter. The 3D Vision Emitter is required for stereo on 120 Hz LCD monitors. You will also need new shutter glasses from Nvidia, but these some with the emitter. I'm not sure the reason, but I'd guess that the older emitter can't transmit the signal at the correct frequency to get 60 Hz to each eye. On a side note, consider which operating system you are running on the system to be used for stereo. You'll need the 3-pin stereo connector if you want to do stereo in Linux. For Windows it isn't required. Some computers that Dell and other manufacturers sell with FX3800 cards don't have one built in, and you will need to buy an adapter that hooks into the video card to provide the port. 2. The normal 3D Vision system uses IR signals to communicate between the emitter and the shutter glasses. 3D Vision Pro uses RF signals for communication between the glasses and the emitter and has a longer range and doesn't require line-of-sight like the IR system (hence the hefty price difference you've noticed). I don't believe the glasses from the normal 3D Vision kit are compatible with the 3D Vision Pro system due to the difference in signaling systems, but I haven't tested this. If you're going to be sitting in front of a monitor doing modeling and don't have alot of IR interference in the same room, the normal 3D Vision version will suffice for your needs. 3D Vision Pro is more geared toward having large meeting rooms and presentation halls equipped so everyone in the room can view 3D on a large screen driven by a 120 Hz DLP projector. 3. I don't wear prescription eye glasses, but I do have long modeling sessions without any discomfort wearing these. They come with several inter-changable nose-pieces so you can pick the one that fits you most comfortably.

Is it true that the Nvidia 3D vision is the only solution for the stereo in LCD? 2. Nvidia supply two kinds of 3D emitters. One of them is 3D vision, while the other one is 3D vision pro. Which one is sufficient for crystallographier user? (3D vision pro is much more expensive than 3D vision) It seems that 3D vision is for home user and powered by the Nvidia GeForce series graphic cards. While 3D vision pro is for professional user and powered by Nvidia Quardro series graphic card . 3. It looks that the Nvidia 3D glasses are very compact. Is it comfortable for someone like me already with eyeglasses? Thanks Yu -- Yu Zhang HHMI associate Waksman Institute, Rutgers University 190 Frelinghuysen Rd.

Check pymolwiki for the full description of setup. It should work for coot too. http://www.pymolwiki.org/index.php/Stereo_3D_Display_Options Nian On Fri, May 6, 2011 at 10:27 AM, zhang yu ccp4f...@gmail.com wrote: Dear colleagues, Sorry to present the stereo issue to the board again.

I think all major programs used by crystallographers use Zalman option. I know that coot and chimera do as does the version of pymol I have running (which is old). I don't know about other programs, but I don't know why not. Dave Sent from my iPhone On May 6, 2011, at 12:04 PM, zhang yu ccp4f...@gmail.com wrote: Dave, thanks. There is an option for Zalman stereo in Coot. Could Zalman stereo also display properly in Pymol? Yu 2011/5/6 Dave Roberts drobe...@depauw.edu I'm very happy with Zalman passive stereo. No hardware requirements beyond Zalman monitor. Monitors cost $500ish for 21 and 700ish for 24. Any video card, any software. Glasses are the same as movie glasses ($2 per pair), no batteries, no flicker. Very nice really.

Re: [ccp4bb] Stereo solution with Nvidia '3D vision' or '3D vision pro'
We recently had issues setting up a 3D projector and have tried lots of combinations of monitors, drivers, cards, glasses, etc. The answer seems to be that interchangeability is very complicated and you won't know unless you try it. For example, with the last version of the Nvidia driver I tested, the driver refused to put out an Nvidia 3D Vision sync signal (stereo 10 in xorg.conf) unless there was a 3D capable LCD attached. I don't know of any technical reason the Nvidia 3D Vision couldn't be used with a CRT but Nvidia has apparently chosen to disable it (or at least make it hard to enable) in the Linux driver. Going the other direction, using RealD with and LCD system, it might be possible but you probably have to match your RealD emitter with RealD glasses. Older CrystalEyes glasses (CE3 and earlier) generally do not work with LCD monitors because of the polarization in the glasses. We recently got some CE4 glasses and they don't seem to have that problem although in practice we are using them with a projector, not LCD monitors. But I don't really like the CE4's, there is too much of my field of vision under the glasses that they don't cover. We've observed some really weird configurations that appear to mostly work, such as plugging in a RealD emitter and glasses when the driver is configured to output a signal for Nvidia 3D Vision (stereo 10 option under Linux). You don't say whether you are using Windows or Linux and there may be variations in the drivers, variations by card, etc. Regarding card to card variations, we've observed 3D setups in conference rooms with multiple emitters where some Nvidia cards happily drive multiple emitters with particular splitters boosters, but other Nvidia cards don't. The bottom line is if you mix hardware you might have problems and vendors are unlikely to help you. If you have CE4 glasses already, you can try it with an LCD and it may work. Otherwise, if you have to buy new glasses (ie, you have CE3 or older), you might as well get the Nvidia package with the emitter included. 3D Vision Pro uses the 2.4 GHz band instead of IR to transmit the sync signal so if you were setting up a conference room in theory the Pro version might be less likely to leave dead zones in the conference room. For a single user workstation it's very unlikely that you would get any benefit. Just to muddy the waters a bit, I have not seen a working 120 Hz stereo setup working on the Acer GD235 monitor. We have a bunch of them set up, and we put a 120 Hz mode line in xorg.conf. If you ask X11 it says it's running at 120. But if you ask the Nvidia driver or the monitor, it reports 100 Hz instead, and visually there is enough flickering that the monitor and the driver seem to have the correct number. I'm curious if anyone else here has looked in detail to make sure their Acer-based system is running at 120 and found that it is actually doing what people claim it can do. I find the 100 Hz LCD flicker annoying over long periods so I am still a neanderthal CRT user. My coworkers were convinced their LCD systems were running at 120, when they were actually only running at 100. I'm not sure if this is a driver problem or a monitor problem. -Eric On May 6, 2011, at 11:27 AM, zhang yu wrote: Dear colleagues, Sorry to present the stereo issue to the board again.
