Anime girls are represented as \mathbb{R}^2 . All their properties can be expressed with one or two variables, or using a one or two-dimensional vector. They can be represented in an euclidean space as a plane.
However, they have physical properties that suggest that they might have more than two dimensions. For instance, while they can only move left or right, they can also move in a "depth" axis, and when they do their size scales up or down depending on the direction of this "depth" axis. This looks similar to how objects look when they move on a 3-dimensional space.
This indicates that, while not noticeable for the 2D girls, there is indeed a third dimension.
Anime girls are not 2D.

OpenGL: "Yeah, basically the viewport is at the origin of the scene, and if you want to see something you have to move it out of the origin, in front of the view"
Me: "So how do I "move" the viewport?"
OpenGL: "You don't. You just move the scene by performing operations in the matrix"
