It is already have!

I've also tried DDD Ignition driver but it's without borders.

It does? I tried v1.10 yesterday and it doesnt.

does this solution work also with big, projected screen?

Sure, why not. You just need to sit at proper distance, which you need to determine practically.

Anyway you can make prism with other characteristics by tweaking angles, and in theory you can make prism for any viewing distance.

Just tried with v.1.10 - side by side driver, crosseyed, in "Assassins Creed" black borders appears and picture is in proper aspect ratio.

I have done something similar! I have some lenses that are made to do the exact reverse, they let both eyes focus on a point between both of them, but by simply rotating the lenses, they instead create a perception of image off to the side as in front of you, works just like this. Your solution is definitely a lot easier to make, though.

Hey, great idea! That might actually be better than some commercial solutions No ghosting, no brightness loss. Great!

Only thing that bugs me - don't you have to keep your head perfectly straight and at a certain distance from the displays for this to work?

Generally yes, and actually distance is more important than perfectly-straight position.
You can still move head a tiny-bit during viewing, I'm didn't tried this with TrackIR yet, but I think in some small-degrees it can be used.

What is more important if you tired your neck during game, you can put glasses off and continue to play it in perfect mono looking just on one of the projections
Also, my personal note that I'm don't actually move my head during FPS gaming, I think like most of other players,
so considering you don't move too much this method is pretty neat (yes, this is prism-smile, I'm pretty happy of it!)

Speaking strictly theoretically - what if you had a prism with adjustable angles? Would that make distance less of a concern? I could see that possible using a liquid-filled container such as here.

Strictly theoretically it's possible - changing angle will change optimal viewing distance, but for adjustable solution better to use some mirrors system.
This prism (with pre-calculated 18 degree angle between main surfaces) is made to view it from normal distance to computer screen

Couple that with a harness that keeps the visor level and you got yourself a high-resolution HMD Though that might be a bit of overkill...

It would require tinkering with the mirrors if you change your position often, but that's ok - considering the kind of stereo you get is actually near perfect.

I'll try the most basic version of this solution when I have the time, just for the fun of it . It's surely better than crosseyed.

If fiber optics are cheap enough it would be perfect! You would have quality and you could move your head.

Just tested with Oblivion and it works fine with the borders but only in crosseyed mode. The default is still messed up.

Isn't side by side default the correct driver for these glasses? Crossseyed will give you reverse stereo.

No, this stereo-prism is designed to view crosseyed content
If you try to use parallel stereopair you will receive reverse stereo.

Did you build yours prism?

Could you explain how it would work with fiber optics? Not my area of expertise .

Basically, two endoscopes capturing the light from each of the views and guiding them to the eyes. Very expensive stuff.

I don't think it would require as much auxillary stuff as professional-grade endoscopes do... No need for a long, elastic and highly adjustable cable. Unless you want to view your bowel in stereo, that is

Anyway, there's no way to judge the usability of fiber optics in this case without an endoscope.

Do you think this will work?

If it's transparent without colors, sure. Glycerin is working because it has the ability to refract light. Water can do the same but it vapourizes by time and may also leave dirty marks.

This looks like a great idea for full resolution full frame rate and full brightness 3D on a budget! not to mention ghost free 3D like a HMD!
This may even be a better way of building a 2 screen 3D setup than using a Planar Stereo Mirror setup, no need for special mirrors or polarizers.
I have Nvidia 3d vision already but I might just have to make one of these myself! Ghost free 3D for the win

I know this is a DIY thread but for those who are to lazy (or unable) to make their own these might be of interest:

Dont know if it would work with a 2 monitor setup or how good the quality is but thought I'd post it here in case someone wants to give it a try (the prisims slide side to side for IPD adjustment)

Also anyone tried adding magnification lenses to these to increase the FOV? (like using a Fresnel lens on a regular monitor)

This method , could it work with the new Blu-ray 3D , the ones that requires 3D TVs and 3D glasses ?

I have a few thoughts about this;

I have read about making a very large spherical lens using a similar technique. In this case they bent one of the plastic sheets to form a curve. A similar technique might be used to widen the field of view in one direction.

Do any of the available stereo drivers support an adjustment for the chromatic aberration caused by the prisms? I.e. on one eye's image, shift blue to one side some amount and then the red pixels a little bit more. Then, do the same for the other eye, but in the opposite direction. Would they have a similar adjustment for the spherical lens setup?

A bit of internet searching turned up some useful threads regarding fluid filled cylindrical lenses;

A portion of a holography book at Google that has a chapter on these lenses

I wonder if gelatin might be added to reduce any chance of leakage?

Article i read in a sciencemagazine but gizmodo had it by googling: http://gizmodo.com/5116969/eyeglasses-w ... adjustable of glasses which uses liquid pressure to form the lensecurvature.

Afaik there are no stereodrivers that adjust for chromatic aberration and i'm not sure if it's even possible. In real world this phenomena is decreased by using lenses with different density tightly attached to each other. Maybe you can try run a movie through an avisynth script but i have no practical experience of this.

Sorry if I disturb the topic but if we can see cross-eyed content can we see side-by-side content ?

Marcer, if you are asking why we have trouble seeing side-by-side content with our naked eyes, the reason is that your eyes were designed to aim closer together for objects that are closer. They never aim outward from each other, which would be necessary to see side-by-side content. And even if we could, the brain could not interpret it as distance.

Thanks for you reply

Hi , can someone can make me fluid-based prismatic stereoscopic goggles ? PM if someone can

Intresting! I'll have to try this. So how does it work in playing a game in side-by-side off of a single monitor? Does it half the width of your monitor? Does it stretch it back to it's normal size for you? Does it keep the same aspect ratio and leave you with black bars on the top and bottom of your monitor? Blah blah blah blah blah.

If you use the side-by-side mode of the iz3d-driver it does keep the same aspect ratio and leave you with black bars on the top and bottom of your monitor. The prismas will only change the angle of the light.

Awesome, thankies!

Wait, really? Maybe I am missing something, but in my experience, the IZ3D drivers definitely stretch the image to fill your screen.

Standard side-by-side mode is frame-compatible fullscreen (so it squashes the image). If you select the cross-eye option (under side-by-side) then it should keep the aspect ratio.

When I choose that, though, it seems to scale the image to be much smaller than it needs to be (black borders around both sides). Am I doing something seriously wrong?

No. That's just the way it has to be. Standard side-by-side uses the whole surface but since it contains two images it has to be squashed. The crosseyed option maintains the aspect ratio for each view but it also means that the whole screensurface cannot be used.
I guess it's possible to make prismas which are curved in one direction to make it possible to use the standard squashed side-by-side.

Obviously there will need to be black letterboxing on the top and bottom if you expect to fit 2 images on the screen while keeping the same aspect ratio.

Gah, had a derp moment. I went back to try again, and I remembered that I need it unscaled, running in the native resolution of 640x480 side by side with no borders on a 1280x800 screen. As far as I can tell, there is no way to do this. The new span mode they added for dual projectors is close, but it only works with resolutions that are larger than a single display, as far as I can tell.

Definitely. What i meant is that the prisms can be made "horisontal spherical" which allows you to run in squashed mode and that the prisms will magnify the horisontal line only. This way you could watch the images in normal aspectratio even if they're spanned in the display.
I however don't say how easy or difficult it is to make this curvature on the lenses though.

Why would you need a curvature for that, wouldn't it deform the image in a non uniform manner ? I think what would be needed is something like anamorphic prisms, which do the same (squash or stretch) for video projection. It should be quite difficult to create something portable though.

Anamorphic lenses will of course also work since they're designed for this task but then it's not really an cheap'n'easy diy thing anymore (on the other hand finding out the suiting curvature i mentioned above isn't really easy either. ).
I just added some info about how it would be possible to achieve this without sacrifice valuable screenspace and resolution.

Building anamorphic prisms is very cheap, it just needs the same materials than these prismatic glasses. The only complicated thing would be the calculus of the relative prism angles to obtain a correct aspect ratio with a squashed image. And maybe find a way to fix all that on the head too...
