Metaverse Drawing

A. What is the Metaverse

To be precise, the Metaverse is not a new concept, it is more like a rebirth of a classic concept. In 1992, the famous American science fiction master Neil Stephenson described the metaverse in his novel “Avalanche”: “Put on headphones and eyepieces, find a connection terminal, and you can enter the real world simulated by computer and the real world in the form of a virtual avatar. Parallel virtual space.”

In March this year, Roblox, the first share of the metaverse concept, was officially listed on the New York Stock Exchange; A Metaverse company; In August, ByteDance spent huge sums of money to acquire Pico, a VR start-up company… This year, the Metaverse has undoubtedly become one of the most popular concepts in the technology field.

So, what is the metaverse? Why are the major digital technology giants entering the metaverse? How should my country’s metaverse industry be deployed and developed?

There is currently no accepted definition of the metaverse

Accurately speaking, the metaverse is not a new concept, it is more like a rebirth of a classic concept, expanding reality ( Conceptualization under new technologies such as XR), blockchain, cloud computing, and digital twins.

In 1992, the famous American science fiction master Neil Stephenson described the metaverse in his novel “Avalanche”: “Put on headphones and eyepieces, find a connection terminal, and you can use a virtual avatar. Enter a virtual space simulated by a computer and parallel to the real world.”

Of course, the lack of accepted definitions of core concepts is a common phenomenon in the field of cutting-edge technology. Although the metaverse has attracted much attention and expectations, there is also no accepted definition. Returning to the essence of the concept, it can be considered that the metaverse is based on the traditional cyberspace, and with the improvement of the maturity of various digital technologies, a virtual world that is both mapped to and independent of the real world is constructed. At the same time, the Metaverse is not a simple virtual space, but includes the network, hardware terminals and users into a sustainable, wide-coverage virtual reality system. The system includes both digital replicas of the real world and virtual worlds. ‘s creation.

At present, everything about the metaverse is still under debate, and analysis from different perspectives will lead to very different conclusions, but the basic characteristics of the metaverse have been generally recognized by the industry .

Its basic features include: immersive experience, low latency and immersive feeling allow users to have an immersive sensory experience; virtual avatars, users in the real world will have an or Multiple ID identities; open creation, users enter the digital world through the terminal, and can use massive resources to carry out creative activities; strong social attributes, the real social relationship chain will be transferred and reorganized in the digital world; stable system, with security, stability, Orderly economic operation system.

B. Talk about the metaverse you understand

First of all, we need to understand what the concept of the metaverse is. Metaverse is a collection of virtual time and space. It is a virtual world that is linked and created by scientific and technological means, mapping and interacting with the real world, and a digital living space with a new social system. So let me talk about what I know about the metaverse.

First, the source of the concept of the metaverse.

Eight key features of the metaverse: Identity, Friends, Immersive, Low Friction, Variety ), Anywhere (anywhere), Economy (economy), Civility (civilization).

Each feature has a path that it can implement. There are three realization paths: ① Immersion and superposition. The representative of the immersive path is VR technology; ② Radical and progressive. The path to the metaverse has always been radical and gradual; ③ open and closed. The path of the metaverse also has two relationships, open and closed.

Summary: This is all my understanding of the metaverse. In the real world, most of us work and are called laborers. With the entry into the metaverse era, most people are not working, and a small number of people are doing the work of innovating, creating and commanding robots, so most people will change from laborers to play workers in the metaverse era, and have entertainment in the metaverse. play to further generate economic value. This is the logic of capitalization in the metaverse. So the development of the metaverse is very necessary.

C. What is the Metaverse

The term Metaverse was born in the 1992 science fiction novel “Avalanche”, which depicted a huge The virtual reality world, where people are controlled by digital avatars and compete with each other to improve their status, still describes a future world ahead of its time.
Regarding the “metaverse”, the more recognized source of thought is the American mathematician and computer expert F.� Professor Wenqi, in his novel Real Name Real Name published in 1981, creatively conceived a virtual world to enter and obtain sensory experience through a brain-computer interface.

D. Qi Haitao’s Curatorial Program

Abstract Lin Art Space was established and the exhibition “Something Interesting” opened, and some guests took a group photo

E. Is it difficult to get started with VR film and television animation?

It is not difficult, and it does not require basic drawing. The early stage is for zero-based teaching, and it is taught from scratch, so as long as you study hard in the early stage It must be learned that film and television animation design is the current mainstream industry. The development prospects are very good. Now it is more advantageous to enter the industry.

F. What knowledge do VR space design majors need to learn?

With the popularity of VR, more and more people want to engage in and learn VR, and many want to learn VR friends, often do not know where to start, especially the zero-based, if you start with a book, you will definitely not understand, and the enthusiasm for learning is discouraged, then how to learn from zero-based What about VR? In fact, the core of VR is Unity3D, and if you want to learn VR, then you must first learn Unity3D, so how to learn Unity3D? At this stage, you don’t need to understand the principles in Unity, and you can’t understand it. The most important thing at this stage is to understand the process of Unity’s production game. Once you understand this process, you can test whether you really like this kind of work.
2. After understanding the above framework, you will have a bottom line in your heart. What is the use of what you have learned? After understanding the framework, you will start to learn the C# language at this time, because you can try it immediately after learning C# at this time. Try, hang it on the object and make it move, firstly, it can deepen the memory, and secondly, you can know if it is right;
3. After learning the script syntax, you can officially enter the study of unity, it is recommended to start Start learning from video, and then buy a book after you have a certain understanding! When you first start learning, you must watch the video screen. It is best to follow it. He does one step at a time. To study, watch videos online, don’t look at a class or a class in the west, look for a complete set of teaching; Books recommend two officially published books, “Unity5.x From Beginner to Mastery”, “Unity Official Case Study”, these two books are definitely two good textbooks for zero-based students. The knowledge is very broad but not deep, and it is very systematic!
4. If you take all the above mentioned seriously After you finish your studies, I think you have basically gotten started, and you basically have your own study plan. The next thing is that you will not make up for it, and then go to the official website to find case studies. The official website is a very valuable place. Diligently Go! Advanced parts (physical math, Shader, 3D graphics, memory management optimization, network, architecture, system engine, etc.) are needed later.

G. VR is good or not

I. Basic introduction of VR

1. Introduction of VR

Virtual reality technology (English name: Virtual Reality, abbreviated as VR), also known as spiritual technology, is a new practical technology developed in the 20th century. Virtual reality technology includes computer, electronic information, and simulation technology.

With the continuous development of social productivity and science and technology, the demand for VR technology in all walks of life is growing. VR technology has also made great progress and has gradually become a new field of science and technology.

Virtual reality technology (VR) mainly includes simulated environment, perception, natural skills and sensing equipment. The simulated environment is a real-time dynamic three-dimensional stereoscopic realistic image generated by a computer. Perception means that ideal VR should have the perception that everyone has. In addition to the visual perception generated by computer graphics technology, there are also perceptions such as hearing, touch, force, and movement. Natural skills refer to human head rotation, eyes, gestures, or other human behaviors. The computer processes the data that is adapted to the participant’s actions, responds to the user’s input in real time, and feeds back to the user’s facial features. .

2. Development history (4 stages)

(1) The first stage: the simulation of sound shape dynamics is the stage that contains the idea of ​​virtual reality

In 1929, Edward Link designed a simulator for training pilots; in 1956, Morton Heilig developed a multi-channel simulation experience system Sensorama

(2) The second stage: the embryonic stage

In 1965, Ivan Sutherland published the paper “UltimateDisplay”; in 1968, Ivan Sutherland successfully developed a helmet-mounted stereo display (HMD) with a tracker; in 1972, NolanBushell developed the first Interactive video game Pong.

(3) The third stage: the generation of virtual reality concept and the initial formation stage of theory

In 1977, Dan Sandin and others developed data gloves; in 1984, NASA AMES research center developed A virtual environment visual display for Mars exploration; in 1984, VPL first proposed the concept of “virtual reality”; in 1987, Jim Humphries designed the earliest prototype of the binocular omnidirectional monitor (BOOM).

(4) The fourth stage: the further improvement and application of virtual reality theory

Since the 21st century, VR technology has developed rapidly, and the software development system has been continuously improved, which is representative Such as MultiGen Vega, Open Scene Graph, Virtools, etc.

3. Features

(1) Multi-sensitivity: In addition to the visual perception possessed by general computers, there are also Auditory perception, tactile perception, motion perception, and even taste, smell, perception, etc. The ideal virtual reality should have all human perception capabilities.

(2) Presence: refers to the real degree that the user feels that he exists in the simulated environment as the protagonist. The ideal simulation environment should reach the level that makes it difficult for users to distinguish between true and false.

(3) Interactivity: Refers to the user’s operability to objects in the simulation environment and the natural degree of feedback from the environment.

(4) Autonomy: refers to the degree to which objects in the virtual environment act according to the laws of physical motion in the real world

4. Key technologies

1.1 Computer graphics technology

The technology of generating, displaying and drawing graphics with a computer is called computer graphics technology. The graphics in the computer are also represented in the form of data. To display the graphics or draw and print, the data must be converted into lines. Computer graphics technology can not only produce a large number of mechanical drawings, architectural drawings, circuit diagrams and geographic maps quickly, accurately and in a standardized manner, which has become an important part of computer-aided design, but also can produce motion graphics and three-dimensional graphics, making the original drawing impossible. things are realized.

2. Stereoscopic display technology

Stereoscopic display is an implementation of virtual reality. Stereoscopic display mainly includes the following methods: two-color glasses, active stereoscopic display, passively synchronized stereoscopic projection equipment, stereoscopic display, true three-dimensional stereoscopic display, and other more advanced equipment.

3. Visual tracking refers to the detection, extraction, identification and tracking of moving objects in the image sequence, and obtaining the motion parameters of the moving objects, such as position, speed, acceleration and motion trajectory, etc. The next step of processing and analysis is to realize the behavioral understanding of the moving target to complete the higher-level detection task.

4. Speech recognition is an interdisciplinary subject. In the past two decades, speech recognition technology has made significant progress and has begun to move from the laboratory to the market. It is expected that within the next 10 years, speech recognition technology will enter various fields such as industry, home appliances, communications, automotive electronics, medical care, home services, and consumer electronics. The application of speech recognition dictation machine in some fields was rated as one of the ten major events in computer development in 1997 by the American press. Many experts believe that speech recognition technology is one of the ten most important technological developments in the field of information technology from 2000 to 2010. The fields involved in speech recognition technology include: signal processing, pattern recognition, probability theory and information theory, vocal mechanism and auditory mechanism, artificial intelligence and so on.

5. Hearing, force and tactile perception technology In the middle of 2012, many technology companies are studying the natural input methods of computers, such as eyeballs, gestures and voice to achieve control. Intel hopes to develop a unified solution that brings these new technologies together. Intel calls such technology “perceptual computing.”

5.Technical features:

(1) VR interactivity

VR interactivity refers to the user’s interaction with objects in virtual reality The degree of operability and naturalness of getting feedback from virtual reality, including real-time. It is mainly generated with the help of special equipment (such as operating handles, data gloves, etc.), and operates objects in virtual reality in a natural way, such as gestures, body posture, language and other skills, just like in the real world.

(2) Immersion of VR

The immersion of VR refers to the degree of reality that the user can feel as the protagonist in virtual reality, which is the most important part of VR technology. feature. Image immersion mainly includes perception, autonomy, depth information in 3D graphics, field of view of the picture, temporal or spatial response for tracking, and the degree of constraint of interactive devices, etc.

(3) Imagination of VR

Imagination of VR refers to the user’s behavior in the system according to the various information obtained in the virtual reality world. , through the thinking process of logical judgment, reasoning and association, the ability to imagine its future progress as the operating state of the system changes.�Adding the creativity and imagination of virtual reality to appropriate application objects can greatly improve production efficiency, reduce labor intensity, and improve product development quality.

H. Talk to the Metaverse Self! How about the car robot Auchan Z6’s first smart happy cockpit?

I have seen the Z6 conference, this car is still relatively strong, especially in terms of power, the fuel version has 2.0T and 1.5T versions, The 2.0T version of the engine has a maximum power of 233Ps and a maximum torque of 390 N.m. The front-drive is used as the drive. It can be seen that the power of this car is very good, and the start must be very fast. I can run and speed up quickly

I. If I go to a vocational school now, which major is better to study

We often say Reading is the best way to change one’s life, but it is not the only one. Some people do not like reading by nature, and their grades are average. For such students, if they have not been admitted to the ideal school, what should they learn? In fact, I suggest that if you can continue to study, then choose to study in a high school, there is really no way to consider the following way out.

High schools cultivate “academic” talents who will develop into higher education in the future; secondary schools cultivate “technical” talents who are about to enter the society and work by knowledge and skills. “talent. No matter what kind of talent, it is necessary for society, and heroes cannot be judged from the level of diploma. If all you want to have is a professional skill to survive, choose to study technology, or even a junior college later, that is also good. But all this is based on you having a clear goal and being able to learn the professional skills taught by the school.
What major should I choose to study in a vocational school:
1. Automobile maintenance
Learning automobile maintenance technology is a promising and profitable technology. Modern automobile maintenance serves thousands of households. It is a high-tech integration of machinery, electricity and hydraulics, and it has a wide variety of technologies, and the requirements for practitioners are getting higher and higher. In the increasingly globalized Chinese market, the competition in the automobile industry is actually the innovation and competition of automobile technology, and the competition of automobile technical talents. The employment prospects of automobile inspection and maintenance technology professionals are very broad, and the future is bright.
2. Media
Under the development of the Internet, it also has innovations, and there are many new technologies and new ways of working. For example, the popular self-media operations, live broadcasts, etc. are all products of media technology innovation. Although this profession looks very advanced, it actually follows a law of development, and there are also skills to speak of. Therefore, people only need to master the relevant technology, and they can also make a name for themselves.
3. High-speed rail/airline services
These are also popular majors in recent years, but the requirements for students themselves may be higher. On the plane, if you are resistant to this aspect, choose carefully.
4. Computer
In fact, girls can also learn computer, because now with the development of the Internet, the computer industry has always been a very popular job, but in any case, boys do occupy a certain position in this position Advantages, at the same time, due to the limitation of academic qualifications, the room for improvement is general, but as a connection to the new era, it is worth learning.
