My time has come!

The above stereographic image is for cross-eyed viewing (most stereograms are wall-eyed, so you may need to put your finger in front of your screen until this one comes into focus)

This is an image of Honolulu, Hawaii, published by NASA. Note Diamond Head (the volcanic crater) in the south.

Here are some other stereopairs published by JPL:

Wheeler Ridge, California

Mount Saint Helens

Salt Lake Valley, Utah

Wellington, New Zealand

I have never ever in my life managed to make these work, I have no idea what's wrong with my eyes

I don't think the locations are all correct.

TIL I am a walleyed viewer

Dude, these are dope! Thank you!

Wow! Super depth!

These are easier for me than normal Magic Eye pictures, because I can just use the "floating hotdog"* method of putting it right up to my face, letting my eyes get used to being focused there and then slowly moving away from it until it pops out of the page/screen.

*(to do the "floating hotdog" trick, put your index fingers end to end then put them right up in your eye line. Now slightly move your fingers apart until the floating hotdog appears)

Awesome! I cross-posted this to !crossview@lemmy.world :)

Oh, also, I really miss the old JMOL molecular models that you could view in cross- or wall-eyed stereo. Anyone know what software is required to make those?

I’m cross eyed. Can’t get a third dot. Boooooooo

[-] wolframhydroxide@sh.itjust.works 2 points 1 week ago

Did you try the wall-eyed versions below? Those should be smaller on a mobile screen, and many people (myself included) find wall-eyed versions easier.

Ah, thanks for the edit. I still think that these have greater value from a scientific perspective, but I do also have a collection of many stereo images that I could post here for you! They're MUCH older, though:

Sorry for the poor quality here! It's difficult to take nice scans of these since they're curved with age. OH, also, these are wall-eyed, not cross-eyed.

[-] wolframhydroxide@sh.itjust.works 3 points 1 week ago* (last edited 1 week ago)

I agree with the general sentiment, though I believe that the value of these images from the perspective of scientific appreciation outweighs traditional Magic Eye images. I remember, ten years later on, how my professor for the geology intro course let us see images taken over Germany by British intelligence, and you could literally see how they used the stereography to find missiles, because you'd be looking at a bunch of flat terrain and then bam, there's a weird thing poking up out of the ground near that farmhouse. Then, she showed us some of these, and showed us how you could compare the topography in these to those on the topo maps. From a "wow" factor, not everything is going to be as flashy as a Royal Institution Christmas lecture, but this is what science looks like.

ETA: Wait, what do you mean "out-of-focus"?

At my work, we maintain computers for a bio lab that use Nvidia glasses to view stereo images of cryogenically frozen protein structures.

Nvidia doesn't support them anymore, and there was an email thread that was forwarded to us by the lab manager of some scientists discussing the issue. One of them suggested to the others that they could just cross their eyes and see the images that way instead of using the glasses. Funny stuff!

Well, its the first time that i manage to see one of these magic eye images.... but I need to ask. Most of this seem to be inverted (i see mountains as sinks, lakes and rivers are higher than peaks). Is this intended? I'm interpretint it wrong?

[-] porl@lemmy.world 3 points 1 week ago

These ones require crossing your eyes, whereas the other type you relax them (like looking further away).

I find the other type way easier and struggle with cross eye ones. For these images you could swap the left and right portions to get it working the other way.
