What are the two and three dimensions?
In today's Internet culture, "two-dimensional" and "three-dimensional" are two concepts that appear frequently. They represent different cultural fields and lifestyles. With the rise of subcultures such as animation and games, these two terms have gradually become a hot topic among young people. This article will provide an in-depth analysis of the differences and connections between these two concepts, as well as data on recent hot topics across the Internet.
1. Concept definition

Two dimensions: Derived from the Japanese "にじげん", the original meaning is "two-dimensional". It now refers to the virtual world and related culture created by animation, comics, games, etc. Its core feature is a flat and idealized form of artistic expression.
Three dimensions: Corresponds to the Japanese "さんじげん", which means "three-dimensional". Used to refer to the real world, real-life movies, real life and other content. Emphasis on three-dimensional and real physical existence.

According to the latest data, the number of China's two-dimensional users has exceeded 400 million, and the output value of related industries has reached 100 billion yuan. At the same time, three-dimensional culture is also constantly innovating driven by technology. For example, the rise of the concept of the metaverse blurs the boundaries between the two.
