3D pictures- With no glasses!

These are called stereoscopic 3D images/video. To view these 3d images, slightly cross your eyes until the two pictures become three, and then focus on the center one. On the first one, try to get the circle and square to align in the third picture.

i cant cross my eyes THAT much :( only a little...

I can cross them far enough from a distance, but then I can't see the images, nor hold them crossed that long. ALthough I don't doubt the principle, that's how these work
http://www.neowin.net/forum/uploads/...1094805905.jpg

For those of you who can't cross your eyes properly, heres a gif for you.

http://i195.photobucket.com/albums/z...eira/3d1iv.gif

You guys can do it, it just takes a few seconds to get the hang of. Also, you may need to move your head a little to the left or right, forward or back to get it just right but it's pretty neat when you get it to work. ninja...it's really not the same as those magic eye things.

hey, pretty cool. didn't know these. it works, but you have to go pretty close to the monitor for full effect.

Very trippy. It takes a little work to get your eyes crossed correctly to make it work, but it works! Thanks for posting!

obligatory last image.

i just had my mind blown on that leaf picture

WOOT! It actually worked for me this time (except for Ninja's). I crossed my eyes until I saw three images. If I "focused" on the center image, it became 3-D. The last image was hardest for me to see because I couldn't tell what it was at first lol (I didn't look at the pics ahead of time, just scrolled down).

Thanks for sharing!

The most impressive pic, for me, is the mountain range :)

This one has got to be my favorite.

Jeez, I'm experienced at these things, but I can only get the images to overlap about halfway. But these are definitely interesting nonetheless. Guess I should check these out more.


Also, there is a way to look at these such that there is only one image. Take a piece of paper or other flat object and place it at the tip of your nose. Line up the other side along the seam between the images, and focus the image. It works by separating the eyes into seeing individual images that are fused together. Try it for larger images. Fun stuff.

Can't do it. Something must be wrong with the internet. Not my ISP. I mean the INTERNET.

I think some of you might be trying to cross your eyes too much. It isn't a matter of how much you can cross your eyes or get the images to overlap, it's much more subtle then that. Basically you just cross your eyes a little...until the images are overlapping slightly...after that it's more of a change in focal point or perspective. As if you are trying to look "through" the image at a point behind your monitor. Once you get the right position it actually feels quite natural, not as if you are straining or crossing your eyes at all.

Huh?

with the blue sun one, Im trying what aquanina said and im like see 10 different versions/ mixtures of the 2 suns SO COOL

Heres a video tutorial that really helped me learn.
YouTube - 3D without glasses, Cross-Eye HD

Ctrl and + for those who can't get it to go far enough. ;)

Some of the images are too large at standard resolution; so large that your eyes would actually need to be pointing outwards to do it, and not many people have the muscles.

I can do this pretty easily... I used to separate my eyes all the time as a kid; I think I must've first learned how via that trick where you hold your index fingers a bit apart and then make a sphere of flesh appear in the middle. :V

All you have to do is have your eyes facing straight forwards instead of inwards, which is what they do by habit when you're focusing on a distant object. Try focusing on a distant object whilst keeping your concentration on an image in the foreground to get a taste of how to split images.

No...it isn't. When you focus your eyes to see those 3d images posted above, you can just leave your eyes that way and scroll down and see all the images the same...but when you get to the magic eye image that ninja posted...it's wrong. When you look at that magic eye picture in the same way that you see the 3d images, the image is actually overlaid with ninja's avatar and out of focus. Attempting to change perspective to bring into focus just results in the image appearing inverted and looks nothing like what you are "supposed" to see. With the magic eye, you are supposed to see skittles or whatever floating in space in front of the background. But when you focus your eyes on it the same way as you would for the 3d images, then you will see a plane that is the foreground, and the skittles are actually cut out of the foreground plane and move backward in space...like the image becomes reversed. So maybe you aren't seeing the first image that it's supposed to be? You cannot claim that they are exactly the same thing. And if you insist that they are, then you must not be looking at one or the other correctly.

Yes! I finally got these stupid things. (not really)

Aquanina is correct. They are not the same. These stereoscopic ones are taken of the same image, but at a slightly different angle. The same distance as your eyes are apart. Most likely with the new cameras they have that have two "irises"
So that when you cross your eyes and merge them together again, you see it as you would see it IRL.

Gahh, can't get this, my eyes go completely out of focus when i go cross eyed

SO cool. I loved this, thanks Turtle!

FWIW, I had trouble at first too, but I found if I crossed my eyes only slightly, then kind of relaxed into that rather than straining my eyes, it worked like a charm. Every time I tried to "focus" on the middle image I lost my crossed eyes, so don't try to focus on it. Just soften your eyes and relax with your slightly crossed eyes.
HTH... :)

nope.avi

You have to change your focus for all of the images, as they're all different distances apart; the mountain one takes particular effort compared to the sexay one for example because the distance is quite a bit greater. ninja's uses exactly the same principle; it's just that the file format is a lot smaller and hence you need to do a lot less unfocusing. All magic eye pictures do is use a tessellated texture, which hides the original object, and gives you some reference point so you know how far to unfocus. In both cases all that is being done is you are seeing an object or scene from the left in your left eye and from the right in your right eye, and the brain can then perceive the 3D due to binocular vision. That ninja's image uses a plane with stuff in the foreground is totally irrelevant: that's simply the 3D object they chose to represent, and you could just as easily take two photos of a similar scene, or make a magic eye picture without such an object. Here is a magic eye pic with a greater focus distance and more interesting 3 dimensionality to help you understand:

Seriously, you described how the first pics work, and then contrasted it with... nothing. Because apparently you don't know how the magic eye pictures work, and if you took a couple of minutes to check it out you'd find that it's the same.

Because I thought it was COMMON SENSE.

Magic eye images don't use two picture taken from a slightly different angle. Didn't think I had to mention that.

Except they do, it's just a 3D model on a computer instead. Like I just explained and you ignored. :/

How do they? It's one picture.
I can only get the leaf one to slightly work, but it's pretty fucken shit. So I've never experienced these things in action before anyway, but from my understanding
magic eyes have some parts of the image which overlap, which cause the bits that don't overlap to pop out when you merge it together with your eyes.

These stereoscopic ones are taken of the same thing from the angle that your eyes would usually see them IRL. So when they merge you see a "3D" image.

The Magic Eye images are specifically called autostereograms, which use a single-image to achieve the effect. The image is usually generated by computer by repeating a narrow pattern from left to right. By decoupling eye convergence from focusing operations, a viewer is able to trick the brain into seeing a 3D scene. Autostereogram - Wikipedia, the free encyclopedia

The pairs of 2D images are simply stereograms, which use two offset images to achieve the effect. Stereoscopic imaging relies on the use of a stereoscope to present a slightly different image to each eye. The stereo pair can be viewed with the naked eye, if the images are placed side by side. Stereoscopy - Wikipedia, the free encyclopedia

Basically, an autostereogram is a specific type of spectroscopy...and therefore they are not "literally exactly the same thing". The wiggle-gram of the trex someone posted, and the familiar blue/red 3D images are also types of stereograms and spectroscopy, and these are obviously not all exactly the same thing.

It's a subtle distinction I wouldn't expect everyone to be capable of making.

Especially somebody who didn't realise you view them in exactly the same way and hence the basic mechanism.

Once again, you are wrong. They are NOT viewed in exactly the same way. The stereograms are designed for cross-eyed (convergent) viewing, while the autostereograms are designed for wall-eyed (divergent) viewing. They are two entirely distinct methods, and when a stereogram is viewed with the wrong method, the depth information gets reversed and the image is not seen correctly.

I could look at these things all day :P

lol, why have you simply resorted to talking out of your ass?

For wall-eyed stereograms, which are the most common, you simply put the left image on the left, and the right image on the right (Side-By-Side and Cross-Eyed Stereo).

Look at the first picture in this thread and tell me: which photo was taken on the left, and which on the right? Clue: look at the chair in the foreground. ;V

Look Xei...here's the bottom line...which you fail to grasp.

There are two methods of looking at these types of images.

Wall-eyed (or parallel) viewing and cross-eyed viewing. Wall-eyed images are made to be viewed by the parallel viewing method, and cross-eye images are made to be viewed with the cross-eyed method. It is clear that there is a right way and a wrong way to view each image. Autostereograms such as Magic Eye are encoded for wall-eyed viewing and designed to be read in only one way. They will produce incoherent 3D patterns when viewed cross-eyed.

Quote:

---

If a two-image stereogram designed for wall-eyed viewing is viewed cross-eyed, all details on the Z-axis will be reversed - objects that were meant to be seen to rise above the background will appear to sink into it. However, in an autostereogram, repeated patterns generally interfere with one another, causing incoherent 3D shapes.

---

Quote:

We can view stereo pictures in two ways. The normal method is the parallel technique, the alternate method is the cross-eyed technique. It makes a BIG difference which method you use, as they reverse the depth information of the stereo picture you are viewing. A parallel stereo picture's background will appear in front of the foreground figures if viewed using the cross-eyed method, and vice versa. If you cross eyes on a parallel picture the front objects will appear to be in the background.

---

Therefore...magic eye autostereograms that use the parallel viewing method do not use "literally exactly the same" technique as the above images intended for cross-eye viewing. This is simple logic and if you fail to accept it then we'll just have to agree to disagree.

That first black and white image you put up caught me by surprise though... I at first only saw the branches and then as it became 3D I was like... OH :shock:

These Are Awesome

I'm glad someone bumped this thread because it reminded me of something I was doing just about a half hour ago during a nap. I was somewhere in between wake and dreaming, I don't remember if I was in full SP, and I don't think I was seeing any HI...I was just watching static on the back of my eyelids, and decided to try and adjust my view as though I was looking at a magic eye image, as though there was a hidden 3d image inside the static. Well I started seeing all sorts of things hidden in there, it was pretty awesome. Then I decided to try and find a more detailed realistic 3d image like in the ones posted above so I tried the cross-eyed view thing and that worked too. It sorta made me dizzy though because I started flying into these elaborate 3d scenes and it transitioned to full fledged 3d hypnogogia. Pretty awesome. Someone else should give it a try and let me know what happens.

I can cross my eyes and make them seem like 3 images but they end up blurry. :[

+1

Keep trying, just cross your eyes slightly, not too much. When the third image appears, try to relax into it. At first it took me awhile to get it too.

And Aquanina, that sounds AWESOME. Might try it out if I can get all the circumstances to gel :)

It reminds me of the second sight.

God I love these. I literally have a whole book filled with the kind that Ninja posted, except they make shapes and pictures inside of the images.
It's cool hehe I'll post a few when I get home.

Also, I was looking at these at school and everyone looked at me weird.. Haha

Actually I've done a similar thing with my eyes open, just staring at the same spot.
Got really trippy hallucinations. At one point I even had a theory that psychedelics force you in to that perspective of vision, plus something else regarding serotonin, which causes you to hallucinate. But those thing that you see, are there all the time in the area you don't usually focus on.

Obviously I can't do these 3d things properly though, but I just focused sort of not on the object I was staring at.

I spent HOURS on youtube when I first found out about stereoscopic 3D videos... it was AWESOME!

Definitely going to post here, give it a bump, because the OP mountains are amazing.

It seems to work for me when I gently push the outer sides of my eyes with my fingers, which kind of manually crosses them.

I'd like a more blatant in-your-face example though, so I can tell better.

http://www.stereoscopy.com/gallery/ggate-r.jpg http://www.stereoscopy.com/gallery/ggate-l.jpg


Love that one :D

Oh, I love these! I can see them really easily, though I couldn't explain how.







pony! (animated)

I made one of these with a stopmotion puppet from a while back:

http://www.Darkstrider.net/Images/busterphonic.jpg

Oh strained my eyes too much, maybe I'll try later. I just get my eyes little crossed, then it goes back to normal. :pissed:
Well I've had much sleeploss, maybe I'll try them tomorrow. Ugh, my eyes.

OOOOOHHHH now I've finally figured it out! I just crossed my eyes, kind of looking past my nose a great deal, and the third pic in the middle was blurry, but I kept softly focusing on it until it got clearer, and the effect is so perfect!! WAY better than what I was attempting before.

Yeah, that sounds like how I did it. I cross my eyes until a third, center picture is seen, then I adjust my eyes until all I see is the center one (the other two are still there, but it's like they're in my peripheral vision). It's really easy for me to do now-a-days. I used to never be able to see those things lol

It helps a lot if you start by holding a finger up in front of your face and focus both eyes on the tip of it, then move it away from your face and toward the image. When you've just about touched the image your eyes will be almost perfectly aimed,and it just takes a little more adjustment then. Sometimes there will be a dot printed over the center of each picture and you can use those - get the two dots to converge and then just look down at the picture. Then once you've got it you can hold your hands up like blinders to block out the extra images.

Some people can do the cross-eye viewing easily (I can) and some find it difficult but can do the other kind more easily where you go wall-eyed. I can't do that at all. It hurts to even try it. But I can quickly zone in a cross-eye video and watch it for a long time. (Not sure how long - they tend to be short films.. )

Here's a stopmotion video shot by a friend of mine named Ron Cole in 3D:

For the King of Titans - harryhausen90 - YouTube

I didn't embed it because you need to set it up on YouTube to make it work - they recently changed their 3D settings and any vids that were already posted are screwed up unless you go in and make a couple of simple changes. Here's what you need to do:

Click on 3D under the video, then on Change Viewing Method and select Side by Side from the options. Click Half Width and also Swap Left/Right. You only have to swap left and right views to see it with your eyes crossed - if you would rather use the Parallel View option (wall-eyed) then don't swap them.

Here's another one, done by Nick Hilligoss: Walking the Walk

Ooh! I love 3d!
