I clicked with the illusion to see and illusion. Now this is a double disillusion.

#12That is awesome. I can't wait to see the STL files people make so we can all print them up! Meanwhile, here is a single mirror illusion STL file and a video showing off how similar illusions work https://www.thingiverse.com/thing:1970522 You can play with the STL in 3D and get a bit of an idea of how it works.
I think you misunderstood this. This is not an illusion of objects from different angles, but an unintuitive transformation of geometry.

They didn’t misunderstand. If you look at the images included in the paper (this link has them inline: https://journalofillusion.net/index.php/joi/article/view/983...) you can see that it is an illusion that can be created with 3D printed objects.

The linked STL is a different Kokichi Sugihara illusion - by the same creator as this new class of illusions, and part of a body of work in this field that this appears to be a continuation of.

But it is. Those are objects that are mirror symmetric, and the apparent direction they're facing depends on viewing angle, creating the illusion that they haven't actually been mirrored.

#16For anyone who's confused about where to find the images: Click "Figures" in the sidebar on the right.
For anyone who's confused about how this works: The objects aren't what they appear to be from any angle. In fact, they're weird mirror symmetric objects that bend backwards in ways you wouldn't expect. It's our shape recognition that makes them look flatter than they are. This also makes them look like asymmetric objects that are facing a certain direction depending on the viewing angle, and this is the actual illusion.
It's sad that we don't get a 360 degree view, or even a couple of rotations of one of these, because that would make it obvious that the object goes from "proper shape" to "unrecognizable shape" to "flipped shape" depending on angle.
Anyway, when viewed in the mirror from certain angles, first of all the object doesn't change (because it's mirror symmetric). But because you view the mirror image from a different angle, it looks as if it's facing the other direction.

#17This seems like a version of the ambiguous cylinder illusion

#18I am illusioned right now.
Are these special objects? Which figures in the article are thoe being displayed in?
To me, each example basically "works" if you pretend its not a mirror corner but just a solid mirror at an angle. I'm guessing this is not the intent though?

What sidebar? I don't see a sidebar. When I click the figures the site just hijacks my browser history.
I think it's about time companies hire the mentally challenged to be front-end devs. I commend the site for breaking new ground in equity.
