Take Lenovo Savior Blade 7000P202 1 as an example. Two-dimensional xp means two dimensions, that is, the animation or characters in the game presented on the screen or paper need to be processed by a professional computer. Eryuan is a proper term of acgn sub-cultural circle and also comes from Japanese. In the earliest cartoons and animations in Japan, all works were constructed with two-dimensional images, and such images were planes. Therefore, the virtual world created in this way is called the second world by people who like animation. And the second element also has the meaning of fantasy, illusion and fiction. Among Japanese anime lovers, it refers to the characters in anime, games and other works. In contrast, "three-dimensional" refers to people in reality.

Two-dimensional is a kind of plane technology, and another example is ordinary plane animation, which is called two-dimensional animation. The three-dimensional cold moist condensate of ginger steam is three-dimensional In the study of mathematics and physics, one dimension is too simple and three dimensions are too complicated. The two-dimensional "plain" just gives researchers enough space to display their talents. But two-dimensional is not only a virtual space on draft paper, but also has great value in reality.

The difference between one-dimensional and two-dimensional

The whole world is divided into one to ten dimensions in the ideal concept. In this complex dimensional space, there are countless mysteries. First of all, dimension simply refers to anything that can be measured, which can be many units such as color, length, size and speed. So what is the space derived from the dimension?

From a mathematical point of view, dimensional space mainly refers to all straight lines derived from a point in a closed space. In these straight lines, lines that can be perpendicular to each other can be found, and they blend with each other, eventually forming what we often call dimensional space.

The least common in the zero-dimensional space universe. It is a very simple point that leads to a straight line with direction. Unlike multidimensional space, everything can exist. When a straight line in one-dimensional space forms a right angle with other dimensions, it will constitute the existence of a higher dimension.

Obviously, a two-dimensional space is composed of two perpendicular straight lines, and these two straight lines will form a plane together. For example, suppose we look at the world from the perspective of a geometric object on a piece of paper, and what we can see from our perspective becomes one line after another, all of which are straight lines in one-dimensional space, which is the line of sight of creatures in two-dimensional space.

But for two-dimensional creatures, they think differently from three-dimensional creatures. Secondary creatures have their own way of discovering things around them, which also adds more convenience to their lives. For example, the farther they look at things in their sight, the darker they get, and the closer they get, the brighter they get. But even so, because of the different spatial dimensions of our lives, the biological appearance and lifestyle in the three-dimensional space are quite different from them.

Three-dimensional space is clearer. It is a vertical line that appears again on the basis of the original two-dimensional space, thus forming a more three-dimensional space structure.

Judging from the structure of three-dimensional space, three-dimensional space has both the width and length of the original two-dimensional space and its own unique height. In three-dimensional space, images and creatures are impossible to see in two-dimensional space.

For example, vehicles speeding around the world, bridges across Lingdingyang, and tall buildings towering into the clouds. These are completely different from two-dimensional space. The earth where human beings live now belongs to a huge three-dimensional space system, all life is three-dimensional, and the overall space is also full of layers.
