From a technical point of view, the underlying engine is still a 3D engine, but at the same time, the image module contains 2D image display technology, while other engine modules are not much different from traditional 3D game engines.
3D+2D, this is the most popular way of understanding.
2.5D has many applications in film and television, among which the most influential application is Japanese cartoons, such as
Spirited Away
"Green Six"
Steam boy
In famous films such as "Moving City" and "Metropolis". Although he used a rendering method, it was not applied in the game.
mistaken idea
1, in the early industry, people's understanding of 2.5D stayed in a misunderstanding, thinking that as long as it was
3D modeling
The game, which is shown as planar 2D, is called 2.5D. Personally, I don't agree. At the same time, this is also the misunderstanding point of 2.5D..
2. Some people think that 2.5D is just an over-product in which the current 3D technology is not perfect and 2D is outdated. That man thinks it's a mistake. Based on personal experience, 2D and 2.5D are completely independent styles in terms of artistic expression angle and orientation, which cannot be confused at all. In the future,1,2D will not disappear in two years, while 2.5D will sing its own songs on the same stage as 3D, and 2.5D will beat the 3D market, which is also unpredictable.
Why use 2.5D?
This needs to be comprehensively analyzed according to the company's product positioning, the producer's positioning of the screen, and the product demand. Not blind! ! ! Personally, I think the decision made by the father of RO in those years was really insightful, although he was not the first person to use 2.5D technology.
case
2.5D, we take MU as an example, 2D scene +3D characters +3D special effects. This is the simplest way to explain mu.
Why use 2.5D? This should be analyzed from the perspective of development, as well as from the perspective of overall game art positioning and game production requirements, not just from the technical gold content pointed out by Zhou Cheng's friend. Hehe, personally, I think the technical gold content of Mu was much higher than that of some pure 3D games at that time.
MU,RO, the influence and impact of these two 2.5D products in China are deeply felt by everyone. When everyone is surrounded by pure 2D and pure 3D worlds, many players can't find a new balance point. At this time, the launch of 2.5D is believed to be a new flavor in these two kinds of screen games.
Why the game is successful is because there is a novelty among hundreds of products with the same taste. Although this novelty is only a small point, it is already a revolution. The appearance of Mu can defeat Corros, who was very hot at that time. It's not that people don't like it, but that 3D games really don't suit the body structure of China people. Everyone who has played Quake and vomited can raise their hands! !
2.5D technical understanding difficulties
2.5D is really difficult to sum up in one sentence, because 2.5D has various expressions and application methods in production techniques. Moreover, 2.5D is the best way to express the picture whether it is used in realistic or cartoon-style games. In short, looking at the 2.5D picture, I feel that I am no longer being * * * * by the game picture.
Cartoon applications include many ways in 2.5D, ranging from common ways to cartoon rendering technology. 2.5D makes up for many effects that cannot be achieved by domestic technologies in 3D production, which is the current advantage of 2.5d..
Why does 2.5D have a big market in China, and many foreign companies gradually change their strategies to join 2.5D?
1, technical difficulty, the technical difficulty of simply representing a set of pictures in 3D is still very high. After all, it is the best product for graphics application, and many high-end graphics technologies are not mastered by people in Asia and China. For example, the realization difficulty of cartoon rendering technology in 3d games, I believe that the number of companies that can do pure cartoon rendering games in China is probably 0, but companies that do pseudo-cartoon rendering are not excluded, because there are many ways to realize cartoon rendering technology, but it is too difficult to do it hard and the machine can't afford it.
2. Product positioning. Let's not talk about foreign countries for the time being. Let's talk about domestic products. At present, there are no more qualified products in China than planning and art, and
product manager
Plus technical supervisor. However, the current planning is precipitating and blindly focusing on how to put it.
Xifanglong
When it comes to the so-called "cutting edge" with dungeons and golden martial arts, how can we understand the combination of art and technology, while the product manager is most concerned about whether the project can be developed, how difficult it is, and whether the cycle and cost can be compressed, while the technology manager, although he is a technology, can't avoid many tasks above.
perfect tense
Shame, also follow the crowd. . . Over time, do people still treat games as works of art? They are just in the laboratory in China.
mouse
3. Talk about foreign countries. Personally, what do you think of South Korea and Japan? They treat games just like movies and art. Personally, what I like most about the product is the game screen. Since the so-called kimchi game was a great success in China, EQ and SB.
Defeat Maicheng
Later, personally, a set of games, technology and planning are suitable, but the application of art must reach a level.
2.5D and 3D, in the next few years, it is not the concept of who will replace who, but the role of performing on the same stage. 2.5D is not easy to do, nor is 3D. Don't underestimate the technical content of 2.5d..
In short, it's the same sentence. I can't reach my consciousness. When it comes to creation and production, it's just that a few farmers have found something.

Adidas put it on and shouted that I am the brand.
What is the 2.5D painting in ZBrush? Maybe the user wanted to draw a 2D illustration tree in the software at first, but later decided to change the lighting at sunset to the lighting effect at noon. As long as the user adjusts the lighting control, all shadows will be updated in real time! _ As shown in the mountain (left). Users can use an unlimited number of polygons in an image. The user _ measures the characteristics _2000_ 3D _ P, as shown in the following figure (right). Working in 2.5D_J Street, users can add and copy 3D models repeatedly according to their own ideas, create a city with an infinite number of buildings, then apply atmospheric effects, and use various brush tools and filters to complete the city drawing. _ beach _ 1 _ province _ _ _ _ _ _ _ _
The popular 2.5D style, PPT one-click generation of 2.5D is commonly known as "pseudo-3D", which is between 2D and 3D. It is one of the most popular design styles at present, and it is very common in graphic poster design, Banner, UI and web design.
APP startup interface
2.5D illustration
Technical architecture diagram
Of course, there are a lot of these case works online. As long as you enter the keyword "2.5D" on Baidu or Petals and Station Cool, you can find a lot of various works in 2.5D style.
In fact, as long as you carefully observe the above works, you will find that this kind of works have two similarities:
In PPT, there are just three corresponding three-dimensional rotations preset to correspond to the above inclined angles and three faces.
Using these three presets, we can generate the popular 2.5D with one click.
Like the technical architecture diagram above, using these three presuppositions, we can also generate it with one click. We can see that this technical architecture diagram is composed of a base, a container carrying information, and words.
Then change the color of the base to get the above three bases.
Using the same principle, you can get three big bases at the bottom.
Like the following three containers carrying information, they are also completed by three-dimensional rotation presets.
Then change the color to get three containers with different colors.
Finally paste the text.
According to the above steps and principles, then the third base can also be generated with one key.
Finally, copy and paste, and then replace the text content. Please see the animation demonstration for details.
Of course, it is completely OK to do 2.5D illustrations, such as the following 2.5D illustration.
Let's take a look at the mosaic process of moving pictures, and we will know how flowing this process is. Just these three presets can be generated with one click.
Ok, everyone, that's all for sharing this issue ~
