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

This is a community for posting or discussing 3D images using the crossview technique. There is another community for the Parallel View technique and also one for Anaglyph 3D using red/blue glasses.

Keep it fun.

I gotchu bro.

  1. Pick one of the recent images with the dots on top. That'll help. Get the picture up full screen on your phone, as big as it can go.

  2. Put the phone about ~1.5ft from your face. Put your thumb halfway between your eyes and the phone.

  3. Focus on your thumb and notice that in the backgeound, the out of focus images start to partially overlap.

  4. Notice the dots at the top of the image? Try to be aware of them without focusing on them. While keeping your focus on your thumb, move it closer to your face until the dots overlap. You may have to adjust the rotation of your phone a bit.

  5. You can then shift your focus from your thumb to the dots. It may take a few trys, but the dots should stay in place. Slowly shift your focus down to the image, and there you go!

Sure, like this one, for example:

Notice the little white dots up top?

Do you mean the dot at the top ?

[–] [email protected] 2 points 10 months ago (2 children)

Yep! Just get those two dots to line up by playing with tour focus, and then shift your focus to the rest of the image.

It feels a little weird. Just shift you focus from your thumbs to the dots and back again, until you get it to "lock" in, like the other person said. It takes a little practice, but you'll get it if you keep trying.
