Re: [osg-users] Anyone using OSG in Windows with 3 (or more) monitors on 2 (or more) graphics cards ?
Hi Wojtek, We use osg on a dual dualcore opteron system running linux fc7 driving an nVidia QuadroFX 4500x2 with four monitors attached. It works great. The gfx card is a bit pricey and requires the addition of a G-sync board to keep it's two gpus in sync (framelocking). I've tried this same setup with WinXP 32 & 64 bit, but had massive unpleasantness with the MS OS and the nvidia software (drivers, etc). Not worth the effort when we can do what we need on with Linux. I'll be happy to provide more specifics if you want. regards, -bob On Thu, 26 Jun 2008, Wojciech Lewandowski wrote: Hi everyone, Topic says it all.

You're right - I got confused between SoftTH and the Matrox box. I think I remember there being an OpenGL version of SoftTH in the pipeline though, but not sure what it's status is.

Re: [osg-users] Anyone using OSG in Windows with 3 (or more)monitors on 2 (or more) graphics cards ?
Hi Wojtek, Thats the configuration I am after. I don't need one continuous desktop divided into 4 or more monitors. I am looking for the configuration which would allow me to drive four independnt views from one machine. You can do that in both setups. If you have one continuous desktop, you would just use CompositeViewer and divide the whole GraphicsWindow into multiple views which would correspond to the boundary of each screen (in pixels). As I understand it, if you have two cards, you don't have a choice, you need two OpenGL graphics contexts (or more). But you could have two monitors on each card, and then you would have two contexts, each with two views, mapping to one monitor each, and that would give you four views. Is that what you're after? I had thought that kind of setup worked in OSG out of the box, but I've never tried it myself. You seem to say it doesn't work? Perhaps on the Windows side there's some work to be done. I can't really help more, since as I said I've never tried that kind of setup.

Re: [osg-users] Anyone using OSG in Windows with 3 (or more)monitors on 2 (or more) graphics cards ?
Hi Jan, Thanks for the explanation. I also added to the mix confusing TwinView with windows HorizontalSpan but it looks like we all were thinking about the same functionality ;-) A more common setup is to have two GPUs each driving two screens (not SLI! That is something else!) and each of the GPU having its own X server and display number. Then you cannot move windows between the displays and you will have two OpenGL contexts.

Re: [osg-users] Anyone using OSG in Windows with 3 (or more)monitors on 2 (or more) graphics cards ?
Hi Jan, I'm not sure what TwinView corresponds to, as it's more of a Linux/X term. That's incorrect. Twinview is Nvidia's term for their multi-monitor support on their GPUs: http://www.nvidia.com/object/feature_twinview.html Sorry, I just assumed as I hadn't seen the term used on Windows. In the Nvidia control panel on Vista, it's called "Dualview"... (just checked) So that's why I went into that lengthy explanation. I didn't want to use terms that weren't clearly defined for everyone.

On Linux you can have two basic setups: - - Separate displays (Non-Twinview, no XINERAMA extension) - you are running two X servers independently and they function as two heads. Essentially you could plug two mice and two keyboards and have two workplaces out of one machine. With regards to OpenGL it means that you have two independent displays (:0 and :1) with two OpenGL contexts and you cannot move windows from one to the other. - - Twinview (nVidia term)/XINERAMA (generic Xorg term) - you have a large desktop spanning several monitors (doesn't need to be only two) and the spanning can be both horizontal and vertical. From the X's point of view you have a single display (:0 ) with large resolution (usually doubled in one direction, but the screens may have different resolutions - I have 1280x1024 + 800x600 for HMD on my desk) Now Nvidia's Twinview can span only on a single GPU - you can have two screens connected to one graphic card (or how many your card supports). However, if I remember correctly it is possible to configure X to create a large logical display over two (or more) supported graphic cards, even from different manufacturers, where each screen shows a viewport of a larger desktop. No idea whether this works with OpenGL correctly, though - - never had such a setup. A more common setup is to have two GPUs each driving two screens (not SLI! That is something else!) and each of the GPU having its own X server and display number. Then you cannot move windows between the displays and you will have two OpenGL contexts.

If I launch the nVidia control panel I can get to a pane that says "set up multiple displays" and on this I can select "configured independently from each other (Dualview)". If I select this then bring up the standard vista "display settings" dialog I can drag the monitor representations around to give either side by side or one on top the other orientation of the monitors. Launching osgViewer without any parameters gives a display which is spread over both monitors. In fact this is my normal desktop setup. The default OSG behaviour is usually quite annoying as models centre on the join between monitors so I modify this by setting the OSG_SCREEN environment variable to 0 in which case osgViewer only uses one of the monitors. So whatever the default setting is causes the OpenGL rendering context to be spread over both displays. I have no idea what happens with more than two screens :-) Roger ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Anyone using OSG in Windows with 3 (or more)monitors on 2 (or more) graphics cards ?
Hi Robert & J-S, You are right. I confused TwinView with HorizontalSpan. Since I have XP this option is available. But does not work either. Thanks for feedback, Wojtek Hi Robert, Wojtek, I recall a post for Jean-Sebastian Guay in the last couple of months about Vista not supporting TwinView, perhaps I mis-read, but this is what I recall. Perhaps he'll be able to chip in. I'm not sure what TwinView corresponds to, as it's more of a Linux/X term. On Windows XP, we used to have the option to have multiple independent displays (say 2 displays of 1280x1024 - I guess that's TwinView on Linux?) or one combined display (2560x1024). The latter is called "horizontal span" (you can also do vertical span, 1280x2048 for example). Now, on Vista, that option no longer exists (apparently because of the new driver model that Microsoft imposed on the video card manufacturers, but that may just be the manufacturers making excuses). The horizontal span and vertical span modes don't exist in Vista, only the "multiple independent monitors". Note that my experience is only on one video card, two monitors. I don't quite know how that scales to X video cards and Y monitors, and how it would work if the cards are of different types. Sorry.

I recall a post for Jean-Sebastian Guay in the last couple of months about Vista not supporting TwinView, perhaps I mis-read, but this is what I recall. Perhaps he'll be able to chip in. In terms of mixing cards and number of displays on each, I've done this myself with a 7800GT and 8800GTS and it worked fine, I did only one window on each but having played with different configurations in the past I am pretty confident that it'll work under Linux with the NVidia drivers. It's actually been working for quite a few years now. IRIX did this all in the early nineties too, all using X11 in pretty well the same way as osgViewer drives it today.

But maybe twinview will be different. Cheers, Wojtek Hi Wojtek, I have only experience of doing multi-card multi-display under Linux and IRIX. In my own Linux machine I've played with two graphics cards with two outputs, and four outputs. It works just fine once you configure X11 appropriately. For best performance use twin view so that you can drive two outputs with a single graphics context on a single card, then with two cards you'll have two contexts and four outputs. Mileage under Windows will vary of course, on the OSG side things should work just fine, but Robert.
