The Sharp screen as used on the Sharp3d laptop and the standalone screen is a barrier method display www.sharp3d.com One would think then that the vertically interlaced setting in the nvidia stereo options in the nvidia Opengl stereo drivers would work with the display (I am interested in the standalone display). Does anyone know if this is the case? What makes me think that it might not be the case is the fact that when one enables StereoViewerModes on a standard Geforce setup (on another PC machine from my SoftQuadro setup) and one tries the Sharp3d setting the view that appears with (DirectX) stereo apps is what appears to be a mixture of vertically interlacing and anaglyph. It definitely doesnt look like the standard (Seereal) vertically interlaced setting on my Opengl stereo machine. | ||

Hey, much thax for this info!!! ..What this all means in fact is, that barrier is in the terms of sharp good enough to sell a display with that, which means you can print your own barrier for your standard lcd and use their software;) Really really cool!!! | ||

To rephrase my question --- would a Sharp3d screen work with the vertical interlaced setting of the nvidia opengl stereo driver? If it does how come the DirectX Sharp3d stereo setting doesnt look like simple vertical interlacing but has anaglyph-type color fringes too -- (when viewed on a regular CRT display)? | ||

anaglyph? no, it's just a lcd-based barrier grid in front.. the display also has just a resolution of 1024*768, but i'm curious if they use horizontal subpixel orientation to get a better image with this technique.. CRT's doesnt work with barrier due the thick glass between and due the different pixel arrangement... | ||

yes I know it is an lcd-based barrier grid but do this if you have an nvidia Geforce card if you want to see what I am on about -- enable all stereo modes by modifying the registry (the utility here at the Seereal site will do this automatically for instance http://www.seereal.com/_download/drivers/Nvidia_Stereo_ShowAllViewerTypes.zip ) enable Sharp3d type and take a look at the test application does it look like simple vertical interlacing -- on my PC it doesnt -- it looks like a strange mixture of anaglyph and vertical interlacing I dont want to make a barrier screen CRT monitor -- I just want to know if regular vertical interlacing will work with a Sharp3d screen | ||

hi, can you post a screenshot this strange mixtur e? I'm on a cad workstation and dont want to mess up my driver configuration with the stereo driver.. just press 'print' on keyboard, copy/paste in paint and upliod at http://www.imageshack.us/ | ||

I would also love to see a "screenshot" of a full "Sharp 3D" monitor or laptop image, to encourage OR dispell the rumour that it is more than simply a vertically interlaced image! While we're on this topic, could someone with access to a Sharp 3D unit please look closely (eg: 10x or more magnifier) at the actual pixels. Do they consist of 3 VERTICAL bars (RGB) or 3 HORIZONTAL bars (RGB)???????????????????? Uploading a pic of this would also be most welcome! Most Curiously Yours, John Billingham | ||

Can't say for sure, but I had a look at the sharp 3d mode in nvStereo and it looked after a little peeking and poking to be vertically interlaced, but at the R G B level rather than at the full pixel level. This gives a sort of anaglyph effect because each pixel has R and B from one image and G from the other. Sample SHARP 3D Image from nvStereo  | ||

Sorry, that image simply didn't work, anyone know how to edit it out? Try http://www.ponies.me.uk/lentikit/NVidia%20Sharp%20LCS%20snapshot.png | ||

thank you.. really nice!!! and yeah, it looks like the use some special RGB stuff for this.. [IMG]http://img159.exs.cx/img159/5091/rgb7ba.jpg[/IMG] | ||

ugh.. ok! look what there comes out if you deinterlace the image to the 2 source fields: [img=http://img159.exs.cx/img159/9427/bmprgb17jq.png] [img=http://img159.exs.cx/img159/6656/bmprgb29uw.png] | ||

Same image De-interlaced with a crude algorithm specially for sharp3d images http://www.ponies.me.uk/lentikit/SharpA.png and http://www.ponies.me.uk/lentikit/SharpB.png Notice the weird colour fringes, these are an effect of the sub-pixel interlacing - because of every pair of pixels one has the R and B values, and the other just the G value. In these pictures I've crudely combined the values of adjacent pixels to get one resultant pixel. | ||

If you are interested in the proper pattern description + SDK why do you not simply register at www.sharp3d.com and get acces to full documentation ? Btw. latest Quadro drivers can wrapp to Sharp pattern (coled color interlaced) as well ... | ||

sub-pixel interlacing.. thats it! hehe;) | ||

anyone get why they show that the parallax barrier is behind the lcd pixels? http://www.sle.sharp.co.uk/research/3d/2d3dFigure.png | ||

It works just as well behind the image as in front of it.AND, since the Sharp allows "2D" mode, a "switched off" barrier behind the main LCD is less obvious. I still would like a "FIRST HAND" observation of the sharp screen with a magnifier! (which way are those darn "sub-pixels" oriented? Best, John Billingham | ||

This report http://www.dur.ac.uk/computer.science/research/technical-reports/2002/tech-report_05_02.pdf has details on the advantages/disadvantages of placing the barrier screen behind or in front of the LCD image screen (page 25) | ||

Anonymous: I thing that you can register as a person on www.sharp3d.com as well, not only as a company. It is only neccesary to sign a NDA ... You will get acces to detailed pattern description, codes switching the 3D on and of as well as to codes creating the pattern very fast and effcicient ... |
