Experience 3D fun with these particle based 3D scenes! If you do not know how to do cross eye 3D, or you have tried and cannot get it, search it on Google.
@@Icewind007 Yeah that’s what this guy’s saying lol some people who make these just put the same image twice and don’t realize that 3-D only works because it’s from two slightly different perspectives
this is insane, mostly because i never imagined your vision can actually become sharp when your eyes are crossed. when the blurriness faded away my mind was blown
@@Guri012 same i couldnt see it i had to put my phone close to my nose but still blurry :( but it was satisfying cuz now i know why it looks like reality is glitching or i can't see the middle of my glasses
@@starpeep5769 It's difficult because it's a unusual combination of the stereo angle and focal length. Once you have the images overlapping you must try to sharpen the image. This will naturaly decrease the stereo angle. You then have to focus on overlapping both images again. Repeat step 1 and so on. You will slowly sharpen the image while keeping your eyes corssed. After a few cyclesyou'll get to a tipping point where you'll keep the focus without effort.
Now that’s dope. I’ve been doing experiments with crossing my eyes for years, from actually seeing my nose to seeing how far double I can see and still use things correctly, like typing.
About 30 years ago I attempted to start a line of 3D postcards called, “Crosseyed Postcards.” It did not do well. I think most people can’t manage the crossed-eye thing. Although a few people liked it enough to buy one of each. Very few.
@@jeffreygordon7194 No software, I just lined the two images up with the right image on the left… When you crossed your eyes you’d see them correctly. At first I did it in-camera with a slide copier, photographing two slides in a double image, then printing it at a photo lab. I tried doing it myself on an enlarger, but I could only do black & white, and it was very clumsy. I got a computer and printer in the late 90’s but it was just as much work as in-camera, and printers weren’t too good then. I got a copy of “Stereogram” and saw a 3D painting by Salvador Dali that he never completed - inspired me to try hand-drawing stereo pairs, which I got pretty good at. A blood clot in my left retina left me with a small blind spot right in the center of view, so that endeavor ended. Back in the early 80’s I took 3D pictures on slides for a hand-held slide viewfinder (remember the ViewMaster?), or for projection with two slide projectors (or one double projector), a *silver* screen (has to be silver/metallic), and special polarized glasses (projectors need polarized filters on the lenses). There’s a guy who calls himself Dr. T 3D who sells lots of 3D related gear. Just google him. Now I just use red/cyan glasses to look at anaglyphs. Anaglyphs are not hard to make, even older Photoshop Elements has everything you need. Not as stunning as slides projected onto a screen (Watch Andy Warhol’s 3D Frankenstein), but, done right, anaglyphs work very well well. There are lots of anaglyph videos on RU-vid and stills elsewhere. You will need the red/cyan glasses - shop around, they can be bought cheap of you look. I’ve bought them in packs of 50 for around $15. You only need one camera to start out. Just find a scene with no movement, put your weight on your left foot and shoot, then shift to the right foot for the second shot. There is no “right” distance - do several and choose the best looking pair. You will likely have to tilt one image to match the other, then shift left-right, up-down. For more accurate camera movement just get a focusing slide and mount the camera sideways. The images will align more easily than hand-held pairs. By the way, you can do “Giant Vision,” putting a 3D effect on distant scenery by moving many feet between your left and right images - a couple of feet to a hundred feet (best to have two cameras, two tripods, and an assistant). Or shoot out the window of a moving car, but make sure there is nothing close to the road like fences, mailboxes, tall grass, shrubs, hitch-hikers… I learned how to do these things using film. Wasted a lot of film. Expensive. Digital 3D is easier and lots cheaper. There are good videos on RU-vid that explain how to combine a stereo pair into an anaglyph. Also, some show how to “fake” a stereo anaglyph from a single image - some of these are pretty impressive, but not true stereo. Good luck. Have fun.
I've been into stereograms for years. Makes me smile to see it done in a motion picture. This was well done, albeit beauty represented simply. This is easier when the device is father away from your eyes so you can still put the central image into focus.
I've always been able to split my vision into 2. Not crossing eyes (which I also can) but the opposite of it. Only discovered stereograms this year and it is a treat!
The strangest part is how easy it is to keep the center locked in place and focus on it. It’s crazy that we can keep our eyes in that orientation and they don’t default
Wow! I've never been into 3D cinemas and you made me experience it!!! I wasn't able to put the two sides together, but it was already close enough for me to feel the 3D-ness. That's my first time!!!
I've tried over and over, I just see 3 videos side by side... am I doing it wrong? (Note- I don't recommend trying it over and over unless you're sure you can cross your eyes that long without repercussions 🙃)
For those who don't know, this is how VR headsets work, except there is a lens that refocuses the screen when at a distance very close to your eyes, removing the need to physically cross your eyes!
Precisely! On a VR Headset like the Oculus Quest 2, if you take it apart you will see that the screen outputs something similar to this video, and likely some distortion to compensate the lenses.
@@jasond.b-w No, we just meant that this is part of how VR Headsets work, you can do it by yourself by crossing your eyes (i found it easier to just put my phone right over my nose), the headsets just make it more convenient by keeping your screen on focus without having any effort to merge the images in your head.
The lenses in VR headsets are only for correcting the vision. Here the videos works the same as a VR headset, each side is for its corresponding eye, so you need to straighten your eyes by focusing a point further than the screen until both images line up. Same as the Nintendo 3DS, except the pixels are angled and it does this for you.
This reminds me of how i would use graph paper as a child to make almost the same image that I could then cross my eyes and "lock-in" the images that I could then look around in. Im over 55. Grest to see this sort of thing sent to another level. Cheers 🇬🇧
Love the videos but why are they only a minute long? It's takes me a while to get the 3D and by the time I'm there it's finished. Please could you extend these to 3 minutes maybe? Thanks
Hold out 1 finger. Then look past it. You should see 2 fingers in the foreground. Now hold out 2 fingers and look past them. You should see 4 fingers in the foreground. Now adjust your fingers / depth of view until the 2 middle ghost fingers meet in the middle and stack. Do that process with the boxes at the start of the video, then hold that as the video begins.
I basically see three images at once, although I cant focus on the outer two but can focus while cross eyed really well on the middle one. can i get the outer two to go away somehow or is that just how it is?
If you bring your focus more towards the middle you can unfocus the other two, or bring your monitor closer to your eyes but other than that mine works quite well.
This is great! I've been using this technique since I was a child. I started by cross-eyeing repeated patterns and noticed some 3D effects when the pattern was slightly irregular. Then I drew simple 3D stereoscopic pictures on paper - just primitive line art, nothing special. Later on family vacations I used to take cross eye 3D photos of the landscapes. Just take a photo, step a bit to the side and take another photo. Didn't work well with moving water and other movements in the background of course, also make sure your shadow or reflection isn't visible. Other than that, the results were great. Don't know why I haven't been doing this anymore, especially today with smartphones where you don't have to worry as much whether the photos turn out good (back then you'd have to get the film developed and didn't know the result until then).
The crosseyed stuff is specially useful when you play the 7 differences game, where you have two pictures close to eachother. The different stuff gets highlighted. So i can no longer play that game, as i beat it in matter of seconds.
@@AlphaEnt2 Yes, I've been doing that too. In the German tv show "Wetten, dass..?" where contestants can bet on achieving difficult tasks, there was one who could quickly find the one wrong digit in two huge almost identical blocks of little numbers next to each other. I immediately knew how he did it and how easy it actually is.
I remember doing stuff like this in MS Paint -- I'd create a simple tiled pattern then contour out a shape, copy & offset it just a little bit to create a 3D effect. I didn't get too much farther than that (you actually have to repeat the process across the width of the image -- something you can spot in the patterns of stereograms when you know what to look for -- without which, every irregularity in the pattern yields a positive shape in one eye and a negative shape in the other) but it was cool while it lasted.
The brain tends to adjust eye convergence and eye focus in tandem with each other, because that's what's most useful generally, and stereograms (cross-eyed or diverged both) require you to adjust them separately.
I tried this trick in a "Spot The Difference", it's amazing how ur brain knows which picture is the correct one and it doesn't show u any missing items.
Wow, this brings back memories. I remember I used to do this to the bars in shopping trolleys when I was small enough to sit inside them. It made me a pro in cross-eyed 3d puzzles😄
There are two ways to do this, one by crossing your eyes and one by looking "beyond" the image (while keeping it in focus). I did it both ways and the second way looks a little nicer. You see the same illusions, they are just "inverted" from one another if that makes sense. Like if the image was a sphere, one method would make it look like its popping out at you and the other method makes it look like it's an indent
if you are crossing your eyes you will be looking on the tip of your nose, so you need to look at the screen with peripheral vision? It is also very difficult to do this because the eyes in this position start to hurt very quickly, and no matter how much I look at the screen in this way, the two red circles do not connect into one. Should they kind of connect in the middle (in the center of the segment between the left and red circles) or should one of the circles (right or left) disappear? I don't understand
and how do you look beyond the image, are you like looking directly at the screen (not out of the corner of your eye) and imagine that your monitor is transparent and you are looking through it? doesn't help, no matter how much I look
@@nofx7058 try this! hold up your finger to an inch or two in front of your eyes and focus on it. you might notice that you have to strain your eyes in order to do this; this is because you are essentially crossing your eyes every time you focus on objects that are close to you. now, without moving your finger or your head, focus on something behind your finger (like a wall or something across the room). this means you are now uncrossing your eyes. now try this over and over again until you have more control on how much you can uncross your eyes! a lot of people in this comments section are saying that they're "crossing their eyes" to achieve this effect. it would be much more accurate to say that they are "uncrossing" their eyes lol!
@IAmElectrospecter You have a good point here, and I think there actually is a mistake in this video in that the two ways of seeing 3D is mixed up. The animation with the white-particle-explosion seems to be made for cross-eye while the other ones are made for "beyond-looking".
As a child, I thought this was a superpower of mine, given it allowed me to “see through” things; like a trash can in a field, I could “see behind it” by exploiting this same action with my eyes then teenage me learned it was actually a weird difference about me and I stopped telling people about it so I’d feel less odd than I generally did and now i just don’t talk about it, cause i don’t know anyone who really cares but hey, i can still do it, at least
A few months ago I was looking at a standard chain link fence when I accidentally had something like this happen. My eyes were focused in a way that made the fence seem small and close-up, but of course when I reached out to touch it, it was actually much farther away.
I realized later that I didn't have to go cross-eyed, but the complete opposite instead; actually crossing my eyes made further things look closer and viceversa, so I had to awkwardly go separate-eyed 😭
@@dogsareawesome9197 So basically I put my phone close to my eyes but instead I focus on something behind my phone and try to make both images line up while at it
Yes you have to focus like if you were looking at something further than the screen. Each eye needs to focus one side of the screen, so the sight has to be near parallel. This isn’t even close to cross-eye. If you focus the screen you cross-eye already, and cross-eyeing even more won’t get you anywhere. On some websites you can read that the left image needs to go in the right eye and vice versa. You’d have to go cross-eyed so hard to do this, that’s completely silly 😂
I cross my eyes for utility mostly, as a way to compare two objects or images. As an example, you can compare the threads on screws to see if they're the same.
It's really hard for me to keep focus. I feel like I get it to work but then I naturally want my eyes to readjust and so I'm getting multiple different looks all at the same time for instance the number of phones I'm holding changes and sometimes I see one of my thumbs dead center or what I think I see is center. I don't know if any of that shit just made sense
I started rendering steroescopic images like these when i was in college. I never progressed to moving them around, but almost every model I made I added a stereo render to. My professors hated them, I think because they couldn't see what i was doing so I ended up not using any in my final portfolio. If I could do it again, I'd throw caution to the wind and just do what i wanted. Well done, very cool.
omg i used to do this with the bubble test sheets they gave us during major school exams in elementary school. I tried explaining to the other kids but they didn’t understand :/ I’m really good at it now and I can focus while doing this and move my eyes around in the same position, just like how you naturally use your eyes. It doesn’t hurt too. I also see in 3D with vibrant or opaque colors in drawings? My emojis look like they are slightly popping out of the screen. Idk if me doing this alot caused that or what but it can be very fun
For those who are having trouble, don't view it in fullscreen. For some reason, fullscreen made it much harder to get the right focus; when I reduced the size back to YT's default, it snapped into focus.
I can’t cross my eyes so I probably didn’t get the best experience, but I just put my phone screen right in front of my eyes (because you do that for the magic eye effect) and I enjoyed it
Although it puts a little strain on the eyes, I find it very cool and creative! It’s a neat way to hack 3D illusions into a 2D video without special glasses or screens.
The description of how to focus on this is the exact opposite of what i do, which is to relax the eyes as if you were looking beyond your screen. Eventually the two images will align in your vision (it comes instantaneously for me). Ive been able to see these since i discovered them when i was about 8. I had cataract surgery at age 12 leaving me partially blind in my left eye (unable to see perfect detail or focus), but Im still luckily able to see & experience this wonderful form of art ♡
For people who can't see it, here's an easy method: 1 - put your phone at a regular distance of your face (not too close, not too far) 2 - start the video and wait until the beginning of the fireworks 3 - when it happens, cross your eyes really hard, so that you see 2 screens instead of one 4 - slowly uncross them, and when it's perfect you'll know it 5 - if it didn't work, repeat (I don't recommend trying it with the letters, as it is rather hard to focus on them) This worked for me, and I hope it helps you! Have a nice day
@@calmdown4524 Try holding out 1 finger and looking past it. You should notice 2 fingers in the foreground. Now hold out 2 fingers and look past them. You should see 4 fingers in the foreground. Now try to adjust your fingers / depth so the 2 middle ghost fingers meet up and stack. Do the same thing with the boxes at the beginning of the video and it should work.
The way to handle it is to look at tip of your finger and than move it away. Your eyes' lines of sight would slowly separate from one another, which is, as mentioned above, exactly opposite of crossing them. So you need to separate them as far as posible, so each eye looks at the senter of corresponding side image. But, this technique forces your eyes to focus on the spot, which is nearer then the crossing of sights. May be itchy at first and cause myopia if you do it systematically
If you're trying to cross your eyes, stop. You need to focus on a distant object across the room and put the screen a foot from your face for it to work.
Its a great effect, presumably because I know how VR looks and people say it looks like VR, but its just that my eyes get the focus on the point, and the instant the video starts my eyes snap back out to see two images no matter how hard I try to force my focus to stay the same, I try to look up at the fireworks and whooom my eyes snap back into regular focus no matter that all of my willpower is focused solely on maintaining that focus. And now my eyes physically ache, the same ache my arms got today carrying my brand new UPS up a flight of stairs. Oh well, I'll just pretend I was capable of focusing and perhaps create an artificial memory of it happening :P Edit: I did the finger trick to about half distance from my monitor, then moved my finger down in increments until I could take it away, I also had to tilt my head to one side to vertically align the two images to overlap, it seems one of my eyes doesn't rotate the way it should, and from there my eyes focused, I didn't have the dots up either, I had the fireworks already there, but that time I actually managed to see it! For all of one and a half seconds before my focus snapped back again. Also, whenever I blink, which is often for me in particular, my focus is broken entirely since my eyes are odd in that my vision goes slightly blurry for maybe a tenth to a quarter second after every blink, and if I keep them closed for a second then my monitor is completely blurry for a half second until focus is restored. Then again, I am nearsighted and have minor astigmatism in one eye and have frequent headaches around my eyes, so it makes sense I'd have a hard time doing this.
Look at someplace other than the screen (focussed prooerly) and then look at the screen and dont try to focus. 2 dots should merge, and then you need to focus on the middle merged image. If you find it difficult to focus on the middle image, move your head closer or further away (change focal length) from the screen
Hold out 1 finger. Then look past it. You should see 2 fingers in the foreground. Now hold out 2 fingers and look past them. You should see 4 fingers in the foreground. Now adjust your fingers / depth of view until the 2 middle ghost fingers meet in the middle and stack. Do that process with the boxes at the start of the video, then hold that as the video begins.
That's so cool! For a while it was blurry and unfocused, but then it just 'snapped' into place and it was like I was inside the actual video. I could look around it and the illusion would still stay, very cool!
Reminds me of those magic eye books as a kid lol. I find it much more comfortable to look past them in order to make them converge in the distance, than to strain my eyes crossing them to have them converge on a point in front of the screen. If you flip the whole thing upside down you can achieve that effect because it flips the order. But I guess looking in the distance is a bit more difficult to learn at first
This is what I use to speedrun spot the difference games. The difference between the two photos will blink or rapidly appear/disappear due to the inconsistency of the two pictures. Literally takes less than 5 seconds to spot multiple differences.
