Whew... the continuous motion started triggering migraine symptoms until I closed the window.

But it does have a nice 3d effect. For me, the cycle speed seems excessive. I believe someone suggested tying wiggle effect to mouse movement?

I’ll shill a library I wrote to make wigglegrams & stereograms in matplotlib - I think pseudo-3D visualization is super underrated as a technique to understand data! mpl_stereo: https://github.com/scottshambaugh/mpl_stereo

i find it so easy to "switch" to 3D with pairs of images like this, it strikes me as strange that cheap stereo-3D isn't a standard interface element. Other than getting used to making the switch, I don't think there is any cognitive load. Just pairing normal lens focus with a different triangulation distance, which is something we quickly learn to do without thinking when using any glasses or lenses. I find it a lot…

Many people can’t, there is significant variation in how people’s visual systems work. I myself can’t anymore after my eyesight got worse.

The first ones shown are quite neat and pleasant. The "accidental" ones pretty quickly gave me motion sickness as I scrolled through them. They also weren't nearly as interesting, though I couldn't look at them for very long.

Have to bring back split depth GIFs a decade later too? Just works with depth hinting no actual stereo information. https://news.ycombinator.com/item?id=48630210

(The original defaulted to “past 24 hours” for me, which didn’t show anything.)

Somehow the extra motion seems to reduce the illusion of depth, it just seems like a disjointed animation to me.

The ones they generated weren't taken specifically to be wigglegrams so they don't work as well as intentional ones. The biggest problem is number of photos and the consistency of the direction of movement between each image and the next as well as consistent step sizes. They also tend to work better with horizontal movement compared to vertical probably due to it matching our eye layout but that's a guess.

Does anyone know what is the technique they use in some of the documentaries where they use really old photos, but they make them look like this wiggle gram? I know it's not AI because the photos can be decades old, but they still do some stuff which that makes them almost see like 3D.

There are many ways of making wigglegrams. The first method is to capture multiple horizontally displaced shots together at once. There were cameras designed for this in the 80s that had 4 lenses, with the widest about eye width apart; the intent was for them to be printed as lenticular 3d images. The second is to have a single shot and then synthetically create additional perspective, such as by using a depth map.

I have done both of these. For the first one[0], I used a Nimslo 3D and for the second one[1] I drew with pastels on paper, and then drew a depth map in Photoshop and used it to displace pixels horizontally for the novel perspectives.

The OP's "accidental" wigglegrams are mostly of the first variety but, the horizontal allignment is not locked in and the shots were taken not at the exact same time. That's why the parallax effect isn't as strong and they don't look as good as the first 3 images that came from Nimso/Nishika.

What is intresting is that both of these two methods are relevant in the age of modern iphone. Iphones capture multiple exposures together in live photos, so moving the iphone laterally when shooting creates a "boomerang" wigglegram. Iphones also capture depth map from the LiDAR sensor when shooting in portrait mode.

Between increased hardware capability and genai for synthesizing additional perspectives, we could be living in a golden age of wigglegrams. Alas, they are out of style.

Found a guy on instagram who builds a custom stereoscopic camera with 4 identical pi cams spaced evenly (about 1 inch (2.54cm)) away from each other on a line. It creates wigglegrams https://k4mera.world/

Cool concept, but implementation is bad. The exposures vary so much between the separate shots it's giving a stroboscopic effect. Hopefully they fix it in later revisions.
