Since cyviz are the first ones, their prices are outstanding, from US$8500. Are there any other companies making or planning to make a similar solution? Hello Taiwan copycats? We need you to to make a cheaper clones of the Cyviz products! Anyone? http://www.cyviz.com/ | ||

You need only a driver featuring a side-by-side stereo output (VRcaddy? I don't know ...) and a dual-head graphic card. Set a 1600 x 600 desktop, connect two 800 x 600 projectors and it's stereo3d! Giorgio | ||

is it possible to create a single desktop of 1600x800 with a dual head video card? I've got something simular on my notebook but I'm only enabled to set a "normal"resolution for each monitor and I have 2 desktops that don't work as one. If this could be fixed, it would be a great sollution for using de-multiplexers Maart | ||

Should work with dual-head Geforce MX boards (though I haven't seen one yet) : http://www.nvidia.com/docs/IO/90/ATT/TwinView.pdf | ||

1600x800 desktop works fine with a dual-head geforce MX. I've managed to play an above-below stereoscopic video on a 800x1200 desktop, and left eye's picture came on one monitor and right eye's on the other. Should work with a two projector setup, but I have only tried with monitors so far. The card was an ASUS AGP V7100-2V1D - a fairly cheap Geforce2 MX card. This means that stereoscopic video is possible. The problem is 3D games. I haven't been able to make neither the ASUS nor the Nvidia drivers put left and right eye's images on separate outputs. The use of VRCaddy has been discussed at http://www.stereo3d.com/discus/messages/21/377.html? - but I don't know if David Qualman has developed VRCaddy for this purpose yet. Any news, David? A couple of days ago, I asked in the guru3d.com forum if there was a chance of modifying the Nvidia drivers to send each eye's views to separate VGA outputs. I had an interesting reply, something about Quadro. But at that time, I was only checking if there were any replies, and when I went back to read the replies more thorougly, the forum was down (and has been since). Can't wait for that forum to get up. I'll let you know by then (or go there and look for yourselves). Andreas, you suggested a circuit for a vga splitter a year or two ago (sorry, I've been hit by the lazy butt syndrome since then, so I never got to the soldering). I might just get it done, as I've got a colleague with soldering skills who has lots of time on his hands. So if you have suggestions for improvements, please let me know. Alex | ||

There is an alternative soution for writing profesional application witch require speed and 2 viewport output - WireGl. This API makes possible to redirect OpenGl commands from one computer to unlimited nubers of other computers and synchronize them. For stereo you need one server caomputer and 2 client one rendering each eye view ... Thi solution sound a bit expensive, but you can get speed in this way ... | ||

Hi alex, If you would use the wicked3d drivers with no sync-doubler the picture is above-below just like your above-below video. Have you tried those drivers? I think it might work. Maart | ||

Thanx guys, nice idea about 1600*600 desktop, but I'm using page-flipping drivers. Checked out WireGL and couldn't find any info on stereo rendering, besides, it doesn't have full OpenGL support. (maybe the missing parts aren't needed by any apps/games?). Going to test it later. http://graphics.stanford.edu/software/wiregl/ | ||

Yes, there is news. We have developed the dual-head support for WINx3D. It will be released shortly, with our next version of WINx3D. As has been suggesed, we expect that it will work with these devices. To make it work, some slight changes are needed of the applications to satisfy DirectX requirements for Dual-Head. We are working with VRStandard to implement these changes in VRCaddy. I'll keep you appraised as to the progress | ||

Alex, no, the VGA splitter is still nothing more than a quick draft - especially since I wouldn't have any use for it myself, and I'm almost cured from soldering video circuits by my line-blanking experiences (HF is really hell sometimes...) Lazy Butt Syndrome - sounds like something I know so well ;-) - permission to quote ? | ||

The main problem is that dual-head graphic cards don't give HW OpenGL support when you set a large desktop due to a software limitation of windows. I've read this in the Detonator3_Release_Notes.pdf but I think it's true for all graphic chipset. David, will WIN3D benefit of HW OpenGL support? THX, Giorgio. | ||

If WINx3D provides OpenGL support, it would only be indirectly through VRCaddyPro. This has not yet been tested, but will be. Presently, WINx3D does not enhance OpenGL applications - it only has interfaces for DirectX. There are no present plans for OpenGL, primarily due to complexities. We would like to release an interface for OpenGL eventually. | ||

I've got an idea. Look for the next discussion "POLARIZED PROJECTION and PAGE-FLIPPING STEREO OUTPUT" Giorgio | ||

Hi All The Guru3D forum is up again. I've read the reply I mentioned earlier more closely, and it sounds very promising. Alex http://www.guru3d.com/forum/read_msg.php?tid=261&forumid=ubb10 quote: On Quadro boards you can enable quadbuffered stereo and use TwinView clone mode insead of page flipping. All that you need is to patch the driver with SoftQuadro then enable quadbuffered stereo and TwinView clone stereo mode. Unfortunately, TwinView clone stereo mode was introduced in 21.81 and currently available SoftQuadro v.10 doesn't work with this drivers. But I've already created SoftQuadro scripts for these drivers and it will be included in the next version of RivaTuner (RC7). It will also aloow you to enable TvinView stereo mode on older drivers. ------------------ Alexey Nicolaychuk aka Unwinder Unquote | ||

Hi Maart Yes, I've tried it - without success. Unfortunately, I don't quite remember what the problem was. Guess it only came on one monitor ...I've got to write down the results of my experiments in the future with all these hard disk failures in my brain ;-) As far as I recall, I came to the conclusion that the wicked3d drivers disabled the dual-out function.

Maybe res. override can do something here to fill both screens the stereo image can be compiled with wicked3d and res. override too, I will get back on you guys when I'm sober. (I just have something big to celibrate) Maybe tomorrow otherwise next week. RANT: hey Christopher we miss you at this forum. Maybe we learned enough from you that we no longerr need you (no that was just a little joke, i speak for all when I say that we like to hear your oppinion. Thanks anyway! Maart | ||

David, quote Presently, WINx3D does not enhance OpenGL applications unquote It sounds like Winx3D can be supplemented by the OpenGL support of RivaTuner (which as far as I understand will only support twinview OpenGL) I don't want to set my hopes too high, but having Direct3D and OpenGL applications running in stereo on a dual VGA card is something I've wished for for a couple of years. Looking forward to the release! Alex | ||

Resolution override from wicked3d wors on the geforce2 MX board, can anyone who has this board try out the wicked3d stereo drivers with stereo override at 1600x800 in twin view? just don't hook on a sync-doubler so you will have above below view. I think it sould be possible. Maart p.s. resolution ovverride worsk also on these cards with the wicked 3d driver, if anyone has a dual-head board with one of the following type please try this out. 3dfx Banshee 3dfx Voodoo2 3dfx Voodoo3 3dfx Voodoo5 ATI Radeon ATI Rage 128 ATI Rage 128GL ATI Rage128 Pro Intel810 Matrox Millenium G200 Matrox Millenium G400 Matrox Millenium G450 NVIDIA GeForce 256 NVIDIA GeForce2 GTS NVIDIA GeForce2 MX NVIDIA RIVA TNT NVIDIA RIVA TNT Vanta NVIDIA RIVA TNT2 NVIDIA RIVA TNT2 M64 NVIDIA RIVA TNT2 Ultra S3 Savage2000 S3 Savage3D S3 Savage4 | ||

Hi Maart Just gave it a try. No success: the above-below image only appears on the primary monitor - the windows desktop remains on the secondary monitor. Didn't see any 1600x800 setting in the wicked3d panel. Tried with 1600x900 and 1600x1200 instead. Res. override was ON. Are you sure, you're able to choose 1600x800? Intuitively, for your suggestion to work, I suppose you'd need a virtual desktop (specified in the "Display properties"->"settings" panel) of 4:6 (for example 800x1200) rather than the 2:1 format (side-by side?) you suggest with 1600x800. However, there are no settings in the Wicked3D control panel for either 1600x800, 800x1200 or similar. The experiments were done with: Wicked3d 5.02 beta drivers Asus AGP 7100 2V1D graphics card Nvidia Detonator 21.81 drivers WinME PentiumIII 733 MHz on the Wicked3d test screen. I'll be back monday. If you have alternative suggestions, please let me know and I'll try it out. Alex | ||

Alex, I used the wicked3d drivers a some time ago, I could just override the resolution to the resolution I wanted to, I think I was able to type in the resolution I wanted. even odd ones like 800x1200. I will have to check. I meant 800x600 double in height so it's supposed to be 800x1200 instead of 1600x800 I'm sorry for this mistake. I think if you run a game in a window you can position it on both screens. Maart | ||

Alex, I don't own a dual-head graphic card neither I've ever tried an above-below stereo driver but I think this is the best way to get 2 vga sync outputs from any game; an 800x1200 desktop running an above-below driver with no dongle. Why it does not work? Of course it may be WIN OS, the driver or the graphic card. As Maart told us, we can try a lot of different graphic card (anyboby out there can do this?) but I think the main problem is the bad 2-monitors' support of WIN OS. As far as I can guess we can: (1) wait a month for WIN XP release (2) try other drivers: * NuVision GX60 works even in above/below format, can we get the driver? * GLDirect seems to me to deliver the above-below format, am I wrong? * Any other above/below drivers out there? (3) try to understand why current settings don't work * do you use windowed or full-screen applications? * can you play a MediaPlayer window across the monitors? And at full screen? Does your game work in non-stereo mode at full-screen? Does a DVD-player work at full screen? And a QuickTime movie? * have you tried a lower resolution running resolution override like 400x600 (as far as you can set it)? Anyway I aspect OpenGL game to loose HW OpenGL support running them across 2 monitors, so maybe anything above can be of no use. Has anybody tried a dual-head graphic card featuring a Quadro chipset in Twin-stereo mode? If we effort some money (how much?) can we get HW OpenGL support running the NVIDIA solution? Giorgio. | ||

Hi Giorgio My reply is under "POLARIZED PROJECTION and PAGE-FLIPPING STEREO OUTPUT" http://www.stereo3d.com/discus/messages/21/812.html?1000915958 We should have moved the thread earlier, but better late than never ;-) Alex |
