A way to see 3D images without special screens or glasses. Just cross your eyes to overlap the two images.


Posting on Crossview

This is a community for posting or discussing 3D images using the crossview technique. There are other communities for viewing 3D on your screen including the Parallel View technique, one for Wigglegrams and also one for Anaglyph 3D using red/blue glasses.

Keep it fun.

I will moderate according to the Lemmy.World Code of Conduct.

Attempted to creat a cross-view image of a basket of apples. It's not perfect, but it turned out alright!

Oops, I guess I made it parallel view instead of cross-view!

Can you post a cross view version?

Made this on my laptop, so I was able to finagle it to be a bit cleaner, I think... I'm not sure because cross-view doesn't come naturally to me! Let me know how it looks.

Edit: I might have made it worse... I can't tell. 🧐

Nope, you nailed it! This is absolutely stunning, especially for free-hand!

When I've done stereoscopic images without an adapter or cutting and moving layers in my favorite photo editor, I've mounted my camera sideways on a rack focus rig and then slid it side to side.

That's a cross view! 😊

The only minor problem is the images are slightly misaligned. The right image is a bit lower than the left.

I made a quick diagram to remember which way cross view is. Imagine floating above two tall buildings. Each building will show the perspective for cross view images:

That is helpful, thank you!

And yes, I think I misaligned them when I was trying to align them... I'll figure it out eventually.

what is the difference? The other one snapped nicely for me when i met my eyes drift apart a little but i can't get this one to work

[–] KanadrAllegria@lemmy.ca 4 points 9 months ago

This one is cross-view and the other was parallel view, but otherwise I did attempt to align the images on this one a little better, but there's a chance I made it worse, heh. 😅

Try tilting your head slightly and see if that works. Otherwise, if the original one worked for you, this one might be inverted, and the closest apple might look further away. That's how I see it.

Much better. What was ipd? It looks more than 2.5". Did you shot parallel or tow in?

[–] KanadrAllegria@lemmy.ca 5 points 9 months ago (1 children)

I'm afraid I don't know what any of that means!! I free handed this with a single camera, I'd that helps answer any of your questions!

[–] Hugin@lemmy.world 5 points 9 months ago (1 children)

IPD = inter pupillary distance. So the distance between the left picture and right picture. Generally try to keep this about 2 - 2.25 inchs. Though there are reasons to have it be difference.

A few other terms that can be useful.

Cha Cha: what you did. Using a single camera to take the two pictures one after the other.

Tow in: change the angel of each shot to converge on the subject. similar to how the eyes do in humans.

Parallel shot: both shots have the same camera orientation just different positions. (Imo the better method. It prevents camara distortion miss match.

Either way it's a fun picture.

[–] KanadrAllegria@lemmy.ca 4 points 9 months ago

Thanks for sharing the terminology! I believe I "towed in" on this particular image. I'll have to try the parallel shot method next time.

[–] fartographer@lemmy.world 2 points 9 months ago (1 children)

Other than that, the actual composition is beautiful. How'd you shoot it?

[–] KanadrAllegria@lemmy.ca 5 points 9 months ago* (last edited 9 months ago) (1 children)

Thank you! I shot it with my smartphone camera (Google pixel6a), using a steady hand and a vague understanding of how cross-view/parallel view works. I had to retake it a few times, but I am happy with how it turned out!
