This may be a silly question but I want to know the answer to it. I saw this thing called the "impossible object", while they're many different images of this online, it's suppost to be impossible geometry.
Here is an example:
Now as far as logic goes, I know you don't have to obey it in games, such as a flying cow, or an impossible object. So that's out of the way, but what stands in my way is whether or not there is a way to draw this onto a 3D scene. Like is there a way to represent it as a 3D object? Thanks!
Answer
3D computer graphics works based on the mathematics of 3D space. Objects like that cube cannot exist in 3D space - that's why they're "impossible objects" - so they cannot be directly modeled in computer graphics either.
Of course it is possible to build objects that, when seen from a certain camera angle, produce an optical illusion that makes them look like an impossible object.
Or as Jari Komppa commented, it's possible to render things "incorrectly" (mis-sorted for example) and make things look like impossible geometry that way. And there are games that play with 2D/3D perspective deliberately, such as echochrome, Fez, and Perspective.
