Well we humans tend to see objects as convex…like faces … because they are more likely to be convex…the structure of this is quite simple…imagine that the diamond consists of only two sides…
the bottom and one “back”…the differences in the colors of the stripped lines does the rest…its like the necker’s cube…it depends on what we choose to see as the “front”…

this is actually pretty simple. I have accidentally done this with light wave. Thew bottom of the diamond is made of single sided polygons but they are inside out. so you are seeing the back side of the diamond. the top is double sided polys so you see them all the time. but from the bottom of them when tilted away and the top when tilted towards you.

To the guy that said “i’ve seen more complicated illusions than this”… “case closed” – you’re an idiot.

********************************
The upper and lowever portions of the cone are spinning in unison. However, the top of the cone is 100% opaque, whereas the lower portion is translucent. You can see the top of the cone through the bottom portion when the top if farthest away from your perspective.
********************************

That’s how it works. Now scroll back up and check it out again and you’ll clearly see how it works.

We this in my science class it has to do with what side of your brain your using.

Im not sure what the illusion is supposed to be.

Was the initial design supposed to be solid or “hollow”?

Look at it one way and u see through to the backside the entire time. The “field of view” being inside the object. (it spins one way)

Look another way its solid and it looks like the top switches directions. (which ruins the illusion of it being a solid object)

So the question is, which way is meant to be the illusion or how was the “illusion” created?

I think the answer is its not supposed to be “solid” and is simply a case of the “fov” being inside the object. Is that supposed to be an illusion?

the illusion is that goes from solid to transparent

It all depends on which side of your brain is dominant, because it is spinning on both direcions, some people see it spinning right, others, left. Some people see it go backwards and forwards because they are paying too much attention to unnecesary detail

The bottom tip of the jewel is making a 360 degree circle giving the illusion that the direction is changing when it rotates toward the back although its not….pretty cool
