Circles - 3D Stereogram Optical Illusion 

Awesome! So glad you were finally able to see them. And even happier that the first ones you saw were ours. Thanks for watching.

Yesssss, the channel is still replying!!!! Theyre alive

@@Truearbs Alive and well... and always ready to reply.

bro, i saw them on ig then came to youtube to learn to see them and now i am very very happy indeed, i now understand the happiness you speak of😢😂😂

Once you get the ability to see them, it's easier each time. That are absolutely amazing

Many thanks for the feedback. Glad you enjoyed them. More on the way, so be sure to subscribe!

Yes, the 90s posters! I had a poster with a hidden eagle flying over a mountain in my college dorm room. Bought it at a mall kiosk. Hooked on stereograms ever since!

@@Eyetricks3DStereograms Cool. I think I remember an eagle one like that. I had a poster hanging up, but don't recall the design now. Thanks for posting these.

Thanks! We've got more Yin Yangs to view here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ZieIF769tj4.htmlsi=Z3SO_TmvH53Gwg_L

Thank you, glad you liked them!

Glad you liked the spherical yin yang. This was our first video that we ran longer (with slower transition times between each image). What did you think about the timing on the transitions? Too long, too short, just right?

Hello, the timing I think was perfect Not too long not too short Would you consider adding two dots at the beginning to prepare the eyes for the video? The video was amazing thanks

Thanks for the great feedback. Will look into the two dots at the beginning of the videos, appreciate the suggestion.

I saw at least 3 yin yangs

Thanks for watching!

пожалуйста! You're welcome! 😊

😂Glad you were able to see the 3D! Thanks for watching and hopefully you tune in to our future videos.

Which image? The one from the thumbnail?

You're welcome!

I've seen some of the animated stereograms online and they are very interesting. We've never really tried a long form one as it would be a tremendous amount of effort. Here is a really short and simple attempt we had at an animated effect. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-4eEEmaMvlOY.html In order for the animation to work, you have to cycle through a series of different stereograms (could be hundreds or more depending on how long the animation is) that all have slight variations. It's kind of like the old flipbooks that created an animated effect when you quickly flipped the pages. Every time you vary the hidden image slightly, the base pattern has to shift in order for it to work properly. I don't see how you could hold the base pattern constant and get an animated effect.

@@Eyetricks3DStereograms Yeah, of course we have to shift the base pattern slightly, but otherwise it could stay the same, while continuously changing the hidden 3D shape, to display e.g. a bouncing ball or a running dinosaur. It's interesting that you say it would be a lot of effort -- I assume you don't have a software solution which simply gobbles up a base pattern and a height map?

@@cube2fox Right, the base pattern would have to change (even if just slightly) for each different change in the hidden image. I can't think of a way you could keep the pattern 100% constant. We definitely use software to help put everything together. I think it would be a lot of work, because to have any meaningful animation, we would have to generate say 100 different hidden images (from a 3D model) in the different positions. We'd then have to run them through the software against a base pattern creating 100 different stereogram images. Putting these together in a slideshow type sequence with very short transition times could then generate an animated effect (like a flipbook). I'm not sure how fast the transitions would need to be in order to have a smooth animation. A quick Google search says that 24 frames per second is normal in animation. So 100 stereogram frames would generate only a 4+ second animation! You'd need 1,440 images (!!) for a 1 minute video. There is probably some software that could help with the manual nature I described above, but we haven't seen it.

@@Eyetricks3DStereograms Yeah, without a full software solution it would be not worth the effort. There is actually a 2014 music video (Young Rival - Black is Good) which is a completely animated autostereogram. I guess they have used special software for it. But they use random noise patterns, which change completely every frame (not just slightly to change the hidden image), which gives an unnecessarily noisy overall result.

@@cube2fox The Young Rival video is very cool, but yes, the pattern is quite noisy. I found an article where the director talks about how they created it: www.indiewire.com/news/general-news/watch-can-you-see-the-hidden-images-in-this-magic-eye-music-video-30387/ It sounds like quite a process!

Flabbergasted! We love to hear it! 😁

Oh no, a stereogram-induced headache? Make sure you take a break and let those eyes rest!

I thought the last one was supposed to be a peace sign

​@@suffering8948you complete the task👏🏻

You're the 3rd one we've lost today!

That's a good thing, right?

@@Eyetricks3DStereograms it's kind of weird not being able to totally comprehend a 2d shape that fits in my field of view without carefully looking around it.

@user-pt2dy7br3c Wow, you are really good at these!

Most of our designs are meant for parallel viewing. We find that this is how most people view them. If you are interested in stereograms designed for cross-eyed viewing, try this one: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ZZaMGy3oDOU.html

Who doesn't like a good yin-yang?

Яркие картинки, приятно рассматривать и музыка фантастическая, спасибо большое!

​@@user-fm5yx5mf4i Thanks for your feedback. Appreciate it!
