1. Computer graphics (CG) is a kind of science that uses mathematical algorithm to transform two-dimensional or three-dimensional graphics into grid form of computer display
simply speaking, the main research content of computer graphics is to study how to express graphics in the computer, and how to use the computer to calculate, process and display graphics. Graphics are usually composed of geometric elements such as point, line, surface and volume, and non geometric attributes such as gray, color, line type and line width. From the point of view of processing technology, graphics are mainly divided into two categories, one is based on line information representation, such as engineering drawings, contour maps, surface wireframes, etc., the other is light and shade maps, which is commonly known as realistic graphics
one of the main purposes of computer graphics is to use the computer to proce pleasing realistic graphics. Therefore, it is necessary to establish the geometric representation of the scene described by the graph, and then calculate the lighting effect under the hypothetical light source, texture and material attributes with a certain lighting model. So computer graphics is closely related to another subject computer aided geometric design. In fact, graphics also takes the curve and surface modeling technology and solid modeling technology as its main research content. At the same time, the results of realistic graphics calculation are provided in the form of digital images, and computer graphics is closely related to image processing
the difference between the two concepts of graphics and images is more and more blurred, but there is still a difference: image only refers to the gray information in the form of bitmap in the computer, while graphics contain geometric attributes, or more emphasis on the geometric representation of the scene, which is composed of the geometric model of the scene and the physical attributes of the scene
the research content of computer graphics is very extensive, such as graphics hardware, graphics standards, graphics interaction technology, raster graphics generation algorithm, curve and surface modeling, solid modeling, realistic graphics calculation and display algorithm, as well as scientific computing visualization, computer animation, natural scenery simulation, virtual reality and so on.

2. "CG" is the abbreviation of computer graphics. With the formation of a series of related instries using computer as the main tool for visual design and proction, the field of visual design and proction using computer technology is commonly known as CG in the world. It includes both technology and art, and almost includes all the visual art creation activities in today's computer era, such as graphic design, web design, three-dimensional animation, film and television special effects, multimedia technology, architectural design and instrial modeling design based on computer-aided design, etc
in Japan, CG usually refers to digital works, from pure artistic creation to advertising design, which can be two-dimensional, three-dimensional, static or animation. In a broad sense, it also includes dip and CAD. Now the concept of CG is expanding. The media culture proced by CG and virtual reality technology can be classified into CG category

CG application field:
Architecture
in today's booming China, CG technology has a very important application field construction engineering. For the meaning of CG itself, computer graphics is widely used in construction engineering
in the Renaissance, architects showed the public the visual scene of future architecture by making equal scale architectural models and hand-painted oil paintings, which continued until the end of last century. From 1960s to 1970s, people began to pay attention to computer graphics technology. At the beginning, the graphics and images presented by the computer are still very poor, but people still realize that the computer is convenient, intuitive and can provide a variety of possible advantages. In the 1980s, computer graphics technology graally matured and began to be applied in film and television, engineering, instrial manufacturing and other fields. Computers began to help architects with aided design. Architects used computers to design and draw building plans, elevations and sections. At the same time, the proction of building models was graally controlled by computers. By the mid-1990s, China began to have the instry of computer drawing architectural renderings. In today's view, our early technology is simple and crude, but the struggle and exploration of the Chinese people in this period can not be ignored. In the late 1990s, people found that the simple static rendering can not play a more comprehensive role in the expression of the whole architectural design scheme and landscape simulation, so the architectural animation and VR technology began to enter the market
film and television
from two-dimensional to three-dimensional, from graphic printing, web design instry to three-dimensional animation, film and television special effects instry, CG with the continuous improvement of technology, the application field is also growing, and now it has formed a considerable economic instry
from Terminator 2 in 1991 to avatar in 2010, we feel the qualitative leap of CG. Nowadays, film and television special effects, 3D animation proction and 3D game proction have become the forefront of CG development
toy story, the world's first movie made entirely with computer animation, breaks through the limitations of digital technology in the film instry and opens up a new way for film proction. At the same time, world of Warcraft, launched in 2005, is the best example. It has made countless Warcraft players realize the magic charm of CG with its magnificent scenes, beautiful background, highly simulated environment and exciting stories< In 2011, "Transformers 3" and "Shrek 3" topped the box office. All of them indicate the future of film animation. China's first full three-dimensional animated film, Mobius circle, was successfully released in 2006, which laid the first step of CG film and television in China. Now, with the continuous development of CG film and television in China, many CG film and television companies have emerged, which has promoted the development and employment of the whole instry
in this short period of more than ten years, relying on high-end science and technology and with unlimited creativity as the content, CG has completely subverted the traditional visual era and opened up a new era of brilliant images. CG animation has brought nearly 100 billion US dollars of economic profits to the powerful countries of film, television and games. It can be said that CG has formed an instry in the United States, Japan and other countries, which has a profound impact on their economic and cultural development.

Image data processing and computer graphics refer to the graphics created by computer. More specifically, special software and hardware are used to represent and control image data on the computer
The development of computer graphics makes it easier for users to interact with computers and better understand and interpret various types of data. The development of computer graphics has a profound impact on a variety of media, and completely changed the animation, film and video game instrynowadays, computers and computer-generated images come into contact with many aspects of daily life. Computer images appear in television, newspapers and other places, and play an important role in weather forecast, medical investigation and surgical operation. A well constructed chart can present complex statistics in a way that is easier to understand and interpret. In the media, "such charts can be used to illustrate documents, reports, papers," and other presentation materials
Many powerful tools have been developed to visualize data. Computer generated images can be divided into several types: 2D, 3D and animation. With the improvement of technology, three-dimensional computer graphics become more and more common, but two-dimensional computer graphics are still widely usedin the past decade, applications in other specialized fields have been developed, such as information visualization and scientific visualization, which are more related to "visualization of three-dimensional phenomena (architecture, meteorology, medical treatment, biology, etc.)", emphasizing the real rendering of volume, surface, light source, etc., and may be a part of dynamic (time)
extended information:
in terms of benefit, CG animation proction is very efficient compared with traditional animation proction. First of all, in the CG animation itself, has saved some expenses. For an animation film, if an ordinary traditional animation company has 3000 to 4000 employees, the monthly output can reach 200 copies. This kind of work efficiency is amazing
Of course, it ignores the input of human and material resources. CG animation does not need substantial paper, almost completely using computer proction, saving physical costs, but also help environmental protection. Because CG animation proction is not as many processes as traditional animation, the speed is also far faster than traditional animation. It usually takes two years to complete a filmsecondly, in terms of revenue, CG animation's film revenue is also considerable. Take Toy Story 2 as an example, the global box office revenue is US $485 million, and the global box office revenue of Taishan is US $435 million The box office of Shrek has reached 528.9 million US dollars. It is conceivable that all CG animated films have become the most profitable film type in Hollywood
of course, CG's "very efficient" and "very economical" may not be accurate, so we can't generalize. Because CG animation realistic proction cost is very high. For example, if you want to take a shot of a curtain fluttering gently in the sun or a leaf falling with the wind, I'm afraid it's much more convenient and cheaper to take a scene than to make the same effect with CG
However, if you want to take a panoramic view of thousands of people, CG will definitely be more cost-effective. Therefore, if CG technology is used flexibly, it can bring infinite benefits only in film and television8. Homo
the meaning of Homo in animation culture comes from Japan, and the record of Homo in China originally refers to people with the same aspirations and good friends. It refers to "self creation without commercial influence", or "independent" creation. Compared with commercial creation, it has greater freedom of creation and the taste of "whatever you want to create, you can create". Tongren is a self-made publication of this kind of creation. This cultural circle is called "the same people"
it is specially noted that "the same person is not only the" second same person "who creates the original works for the second time, but also the works that are original by the author but not commercially operated." For a supplementary explanation of the definition of this point, please refer to the paragraph "once with others" in this entry
CG
computer animation is a technology of making animation with the help of computer. It can be roughly divided into two kinds: two-dimensional animation (2D) and three-dimensional animation (3D)
