hi I need to adapt a pair of shutterglasses so that the lcd panels are bigger (size around 10x10 cm.) does anyone know of how to accomplish this and where to buy cheap lcd panels? any help is welcome Maart | ||

Wild idea: Would it be possible to get a really old notebook (cheap) with a b&w panel, rip out the panel, remove the backing, make the connections longer, then connect the notebook via parallel port or serial (use RTS and DCD lines) to shutterglasses output on your main PC. Have a small DOS program black out half of the screen according to signal received. You would then not have two 10cm by 10 cm panels, but the big one could serve you just as well. I am guessing you want to prepare a kiosk-like stereo viewer, where people walk up to a box and can see through the glass to get 3D stereoscopic vision? | ||

Hmm... on closer thought, the switching speed of old LCD panels is probably not sufficient for 120 Hz :-( | ||

Yes I was thinking the same thing. The idea behind all this is to use a shutter system to work with a cave like system. the cave is created by a network in wich each pc connected to a network renders one screeen of the cave. to use 3d the frequency of the page-flipping signal is different on each pc. A solution would be to first de-multiplex the vga signals from the pcs into 2 seperate streams, than use an lcd pannel in front of the projectors to block out one of the 2 signals and than the other. if these lcd panels shutter in the same frequency than the shutterglasses of the viewer, the walls of the cave sould shutter left and right images all at the same time and you would see 3d on all walls. another option maybe would be to use circular polarisation. since 45 degree polarisation wouldn't work bequase the ceiling in the cave. But I don't know anything from circular polarisation, if someone here does please inform me. would be possible to get 3d with being able to turn my head 90 degrees and still see 3d? In my opinion the shutter solution should work but polarisation would be cheaper and easier to use. so this would be prefered by me to use. But I don't know if it will work. please everybody let me know what you think. Maart | ||

Hi Maart, are you sure the network solution to be the best one? I've been told XINERAMA under Linux can support a lot of graphic cards in one PC. Maybe things would be easier. About 1 year ago I've tested this one: I wear a shutterglasses hanging the other one (in sync) in front of the projector. Try the same with your system (closing one eye and then the other), if it works I think the active stereo solution to be better than the "polarized" one. Giorgio. | ||

this XINERAMA sounds interesting, can you give more info about it? "I wear a shutterglasses hanging the other one (in sync) in front of the projector. Try the same with your system" This is the system I discribe in my previous post. But the thing is that I don't think shutterglasses will have panels big enough to fit over the lens of a projector, That's why I wanted to adapt the shutterglasses. which shutterglasses have the biggest panels anyway? Do you know anything about circular polarisation? (if it works it would be cheaper bequase I don't need a de-multiplexer for each signal. Maart | ||

Take a look here www.x.org/r6.4doc/relnotes/relnotes.htm I don't know anything more but keep me updated. Giorgio | ||

Sorry, I haven't checked it ... it worked some weeks ago. You can try a web-search ... I've no other link. Giorgio. |
