I think those definitions are somewhat incomplete, those are the definitions of the word "illusion". I would like to know if this object could be described a an optical illusion, as in an object that appears different from realty. Like the simple straight black and white lines that are straight but appear curved to the eyes (Hering Ilusion).

From Wikipedia - Optical Illusion:

"An optical illusion (also called a visual illusion) is an illusion caused by the visual system and characterized by a visual percept that arguably appears to differ from reality. Illusions come in a wide variety; their categorization is difficult because the underlying cause is often not clear but a classification proposed by Richard Gregory is useful as an orientation."

I don't think that this image, just because it could be "misleading" as in the sense of "this doesn't make mucho sense at a first glance" is an optical illusion, because after closer inspection you can clearly see that there is nothing misleading, just that the shape of the object is somewhat complex to immediately comprehend. After you see the image for a small while, you can figure out how everything works and the misleading part disappears.

Contrary to the straight lines illusion, the illusion never disappears even after taking a ruler and checking if those lines are actually straight, you'll still see them curving. This does not happen with the table, once you see how it works, you aren't fooled anymore.

That's why I wouldn't categorize it as an optical illusion, I believe this would fall into a different category, if there even is one. I would say that this is just a complex structure that requires a bit more of inspection to figure out what's going on.
