Graphics

=**Computer Graphics**=

Computer graphics is a virtual sphere in computers. By the computer graphics, people can use computer to draw graphs and simulate objects and three-dimensional space from the real world to the virtual world.

=Imaging=

- 2D Computer graphics
2D computer graphics are the computer-based generation of digital images from two-dimensional models.

- 3D Computer graphics
3D computer graphics in contrast to 2D computer graphics are graphics that use a three-dimensional representation of geometric data that is stored in the computer for the purposes of performing calculations and rendering 2D images. Such images may be for later display or for real-time viewing.

These are the samples of 3D computer graphics from <[]>

=Simulating=

- Computer animation Computer animation is the art of creating moving images via the use of computers. It is a subfield of computer graphics and animation.

A good simple of Computer animation is the movie "Toys"

=Object Rendering=

In 3D computer graphics, object rendering performs in the role of showing how the graphs can be displayed, or rendered on a computer.

A model of the object is created to store the locations, or coordinates, of corner points. Each side of an object is treated as a flat surface bordered by three or more outlined edges. The computer is used to calculate how each object appears in perspective view, and then to draw the outlines on the screen.

=Shading= In computer graphics, Shading refers to the process of altering a color based on its angle to lights and its distance from lights to create a photo realistic effect. Shading is performed during the rendering process. <[|https://cms.cse.taylor.edu/mod/wiki/view.php?id=192&page=Computer Graphics]>

=Areas of Impact=

Business and employment
Graphic designers held about 261,000 jobs in 2006. About 75 percent graphic designers worked in specialized design services; advertising and related services; printing and related support activities; or newspaper, periodical, book, and directory publishers. Other designers produced computer graphics for computer systems design firms or motion picture production firms. A small number of designers also worked in engineering services or for management, scientific, and technical consulting firms.

About 25 percent of designers are self-employed. Many did work—full time or part time—in addition to hold a job in design or in another occupation.

Education
The field of computer graphics in education is evolving due to technological advances in computer programming and software. People who creative and interested in computer graphics technology may want to consider getting jobs as graphic designers. Graphic designers create computer graphics for web sites, interactive media, and multimedia projects using a variety of graphics and layout computer software.

Health
The graphics system can simulate the inside of human body, parts of illness.

Arts, entertainment and leisure
Graphic arts is a term of the art of printmaking and drawing. In contemporary usage it refers to the trade-skills of a graphic designer or print technician. It includes the trades of lithography, serigraph and bindery, among others. Graphic arts as a trade can be traced back to the first instances of the stamped image or word. image source from <[]>

Politics and government
The uses for government can be military. so far most of enemy units can be simulated by the computer graphics. By that technological skill that the auscultation can be imitated.
