What is the difference between CG technology and 3D special effects?

CG is the abbreviation of English Computer Graphics, which refers to the use of computer technology for visual design and production. It includes both technology and art, and covers almost all visual art creation activities using computer technology, such as graphic design, web design, three-dimensional animation, film and television special effects, multi-technology, and computer-aided design of architectural design. Now that the concept of CG is expanding, it has formed a considerable economic industry, and when we refer to CG, we can generally refer to the following four main areas:

CG Art & Design, Game Software, Animation, Comics.

CG animation refers to the animation made by the computer, that is, the animation that the computer has originally made, and the host only needs to **. Its counterpart is a real-time calculation animation, which is an animation that a program needs to be calculated by the host computer. Generally speaking, CG animation is much stronger than real-time algorithms, and it takes up less space than real-time calculations.

However, CG animations lack variety, and it is not possible to change the action on the fly.

3D is the abbreviation of Three-Dimens 3D renderings, which is three-dimensional graphics. To display 3D graphics in a computer means to display a three-dimensional figure in a flat surface. Unlike the real world, where there is a real three-dimensional space, there is a real distance space.

The computer just looks like the real world, so the 3D graphics displayed on the computer just look like the real thing. One of the characteristics of the human eye is that it is near and far small, and it will form a three-dimensional effect. The reason why we can enjoy a three-dimensional image that is really like a real thing is because the difference in color gray scale when displayed on the computer screen makes the human eye have a visual illusion, and the two-dimensional computer screen is perceived as a three-dimensional image.

Based on the knowledge of color science, the protruding part of the edge of a three-dimensional object generally shows high brightness, while the concave part is dark due to the obscuration of light. This understanding is widely used to draw buttons and 3D lines on the web and in other applications. For example, if you want to draw 3D text, you will display a high-brightness color in the original position, and outline it in a low-brightness color at the bottom left or upper right position, so that the effect of 3D text will be visually created.

In the specific implementation, two 2D text of different colors can be drawn in different positions with the exact same font, and as long as the coordinates of the two characters are appropriate, it is completely possible to produce 3D text with different effects visually.

If you want to learn systematically, you can consider signing up for a live online class, and recommend CGWANG's online class. The teacher speaks carefully, you can watch it back after the class, and there are also the same type of recorded classes that you can learn for free (give away lifelong VIP).

Among the training institutions in the field of "film and television special effects technology", [Wang's Education] is the leader in China, and it has not joined the branches, but is a chain campus directly operated by the headquarters. Different from many other large institutions of the same type: each campus of Wang's Education is physically face-to-face, the teachers are hand-in-hand, and there are special class teachers from morning to night, and the liver-bursting learning mode will improve quickly, especially suitable for students with poor foundation.

CG special effects are a type of movie special effects. CG can be understood as computer creation. When traditional special effects methods cannot meet the requirements of the film, CG special effects are needed to achieve them, and CG special effects can achieve almost all the effects that humans can imagine.

Special effects production in the CG era can be broadly divided into two categories: three-dimensional special effects and synthetic special effects. Among them, the three-dimensional special effects are completed by the three-dimensional special effects artist, who is mainly responsible for the performance of dynamic animation, and is mainly classified:

Modeling, Materials, Lighting, Animation, Rendering. Compositing special effects are done by compositors, who are mainly responsible for the compositing of various effects. Main Categories:

Keying, wiping, color grading, compositing, scenery.

CG stands for Computer Animation, which is a technology that uses computers to create animations. It can be roughly divided into two types: two-dimensional animation (2D) and three-dimensional animation (3D).

CG was originally an abbreviation for Computer Graphics. With the formation of a series of related industries that use computers as the main tools for visual design and production, it is customary to refer to the field of visual design and production using computer technology as CG in the world. It includes both technology and art, and includes almost all visual art creation activities in today's computer age, such as graphic design, web design, three-dimensional animation, film and television special effects, multi-technology, computer-aided design-based architectural design and industrial modeling design.

The main majors are film and television animation, games, post-production, special effects, advertising, column bags and graphic design, and the employment agreement is signed after graduation.

1. Features::

With the formation of a series of related industries with computers as the main tool for visual design and production, it is customary to use computer technology for visual design and production in the field of CG.

Animation: Not limited by time, space, place, conditions and objects, the complex and abstract program content, scientific principles, and abstract concepts are expressed in a concentrated, simplified, vivid, and vivid form by using various forms of expression.

Second, the field of application:

In addition to games, it includes graphic print design, web design, three-dimensional animation, film and television special effects, multi-technology, computer-aided design-based architectural design and industrial modeling design.

Animation: film and television, games, commercials.

CG generally refers to digital productions that generally serve the following industries: advertising, film and television, animation, comics, and games. The content is purely artistic to advertising design, which can be 2D and 3D, still or animated.

CG is the English abbreviation of Computer Graphics, and the core meaning is digital graphics. With the development of the times, the meaning of CG has expanded, but it still does not go beyond this core meaning.

Lazy people's understanding of CG is to use the computer to participate in the creation of art works, whether it is completely made of the reputation of the poor with the computer to complete the production, or the later use of the computer to process the processing, all belong to CG works.

It includes both technology and art, and includes almost all visual art creation activities in today's computer age, such as graphic design, web design, three-dimensional animation, film and television special effects, multi-technology, computer-aided design-based architectural design and industrial modeling design. For example, Avatar, it can be said that the entire movie is composed of "CG".

To make those effects, learn math and computer development. If you're interested, try to develop something and you'll understand what knowledge and technology you need.
