First of all, I wasn't sure if this topic is at the right place...

The method is called cross-eye.
How does it work?

You take two pictures at an angle (it works also with videos), one for the right eye and one for the left eye. Then, you place them one beside the other so that when u cross your eyes the right eye will see one picture and the left eye will see the other. Your brain arranges them and it will look like 3D.

Here is a video that explains it pretty well.


There is two other method but I won't explain them in detail cause they are pretty much the same as cross-eye.

There is the animated .gif. All it does is quickly show one picture then the other:


And the last one is with a mirror. All you do is reverse one of the picture so that when u put a mirror in between the two images, it reverses it for your eye that way u don't have to cross your eyes.

Hope this interested you.

That was a really interesting experience. Thank you for the share

I made some 3D images with my camera, here is one of them:


It's was taken in the park in front of my house.
The quality is very high so I may reduce it so it takes less time to load.

Edit: Made file smaller

I'm not really able to move my eyes like that, damn that hurts. I prefer 3d-glasses

wow this is weird.

It will only hurt cause your eyes are not used to be in that position. After a bit of practice, you will be able to do it in half a second. At least it's like that for me.
For my sister, it took her about a day to master her eyes but now she can do it perfectly.

In case anyone is scared that their eyes will stay like that don't worry, there is no risk. In case you don't trust me, I got this for you:


It's just a kind of paper glass that allows you to see the pictures in 3D

And for the people that would like to see a 3D car:


Edit: I tried the paper and it worked perfectly! All you need to do is print the picture, follow what it says and look trough the hole.

I can't cross my eyes

The first time is always the hardest After that, it becomes pretty easy.

Now using www.youtubedoubler.com , I can watch movie destroy shine in 3d

ps, thanks for the share, that is kinda trippy.

First time I heard about this was when I heard a story of a kid who was trying to do this with porn and his mom walked in on him with his face to the monitor cross eyed with porn on the screen. I tried to do the cross eyed thing but it just hurt my eyes.

:<

Is it possible to do it with regular glasses on? Because when I try it... I get triple vision

well it works because you're mimicing the camera taken. The camera has 2 lenses, and is focused on one point. By crossing your eyes, you take the two images and make them into one, just like the camera is doing, and just like your eyes normally do in a 3-d environment.

Since not much people seem to be getting it right, I'll give some new tricks for practice.
1. Put your hands in front of you and move them apart (enough to be able to put a third hand in the middle) then play with your eyes until you are able to see the two hands touching each others. When you get it better, you can move your hands even farther and try it again until you can control your eyes perfectly. (It trains your eye muscles.)

2. I got some simple images that are great for practicing:


For practice, try this illustration from Sir Charles Wheatstone's book The Stereoscope.


Don't expect to succeed the first time. This skill takes conscious effort and concentration. When you do succeed, you'll see the pictures snap into full three-dimensional depth. The picture will look like a wire-frame box. You'll actually see two 3-D images, one with normal depth, one with inverted (pseudoscopic depth). On either side of these you'll see fainter, phantom images with no depth. Ignore them.


Here's some more practice examples:



If you use cross eyed viewing on the pair intended for parallel, or vice versa, you will see a "pseudoscopic" depth, in which near and far are reversed. In the first picture, the pseudoscopic view appears as if you are looking down onto a truncated pyramid. In the second picture, the cone seems upright in the normal view, but tilted back and viewed from its base in the pseudoscopic view. Wire-frame stereo drawings often look interesting either way.

Here's another example for practice.


Now for some practice with actual stereo photograps, for cross-eyed viewing.

It depends, let me explain how the glasses work (simple explanation).
First of all, there are different types of 3D glasses, the Real D 3D (like the ones from Avatar) and the Red and Blue.

With Real D 3D, you will need 2 projectors, one for the right eye and one for the left eye. The Real D 3D glasses will filter the images so that your eyes only see the image that they are supposed to. (You can take two pair of glasses and with one you look at the second pair through the glasses, you will see that one lens is black because it doesn't let the light go through.)
Those glasses will not work on computers.

For the Red and blue it's pretty much the same thing but it can work on computers and in books.

That t-rex one is dope man. Good stuff here, i have 3D Glasses in my drawer haha.

I wish I could see in 3D

Being half blind sucks.

Well, not those kind of glasses, because, I'm near-sighted, and I can't see anything clearly without my glasses on unless I am about 8 inches away from it.

That's normal. If you went wall-eyed, you'd be seeing quadruple. (Or if one's eyes cross too far, as mine often do - I'm used to just crossing them for no particular reason, and thus not caring about the angle)
Each eye sees both images - when crossing eyes at the proper angle, two of the images will overlap, combining into the one which you're supposed to be paying attention to.

I had a book of random neat "tricks" to play with when I was in like, 2nd grade, one of which was "Make a hole through your hand" by placing a cardboard (or paper) tube up to one's eye and placing the hand (or whatever object) against the tube, on the side of the opposite eye. It taught me about stereoscopic vision conveniently early on.

Sorry for that, I miss understood the first time. As EzDay281 said, it will work with regular glasses. I have far-sighted glasses and my father has near-sighted, we can both do it.
