Something I've never understood about 2D/Flatland as a "visual" idea:

In the case of this Mar1d, if I'm on the X-axis, and can only see the Y-axis, wouldn't any amount of detail in the Z-axis constitute a 3D image? The Y-axis stretched even a single "pixel" along Z would make it 3D, right?

Similarly, for Flatlandia: If I'm a 2D square on the X-axis, and can see "around" me on the Z-axis, wouldn't my ability to see anything make the Y-axis be > 1?

I get it, but I still prefer these: https://www.youtube.com/watch?v=KBb9wFP7uZM https://www.youtube.com/watch?v=Gf-2Imh6a54

Correct me if I'm wrong, but those seems to be 3d renderings/animations rather than interactive games, different class :)

If you like this, you'll like Planiverse (1984) https://en.wikipedia.org/wiki/The_Planiverse

A bit like the classic Flatland book, this also imagines a 2D world, and also fosters thinking about higher dimensions. But there's a nice shift: if there's an "up" in Flatland, it points out of the world, whereas in Planiverse, the up is in-world, and we visit the world by looking at it from the side, rather than from above. So the creatures of Planiverse would be great at playing MAR1D.

Planiverse also creatively thinks through a lot of the physical and mechanical realities of living in a 2D world, and is wrapped in a poignant narrative about using computers to connect to alternate realities.

(ah shoot I just learned that the author has turned into a 9/11 truther, but Planiverse remains a cool book)

If the width of a pixel along the Z-axis is arbitrary, and you only see one, no, it would not be 3D. It's still 2D, you just have the ability to more easily see. You gain no new information.

I'm with GP on this one. You say "width of a pixel". That width is a dimension. If that dimension exists, along with X and Y, then it should 3D.

And that's when talking about video-games or computer graphics. In the Flatland example, there are no pixels. The characters shouldn't be able to see each other or the structures on their 2D plane at all.
