The Concept and History of Computer Graphics

Computer graphics is an area of activity in which computers are used as a tool for creating images and processing visual information obtained from the real world. The result of this activity is also called computer graphics.

History of computer graphics

The first computers did not have special means for working with graphics, but they were already used for obtaining and processing images. By programming the memory of the first electronic machines, which were built on the basis of an array of lamps, patterns could be obtained.

Digital graphics applications

The first computers were used only for solving scientific and industrial problems. In order to represent the obtained results better, their graphic processing was carried out, and graphs, diagrams, and drawings of the calculated structures were made. The first graphics on the machine were acquired in symbolic print mode. Special devices appeared, such as plotters for graphs and drawings with an ink pen on paper. The most up-to-date scientific computer graphics make it possible to perform computational experiments with a visual presentation of their results.

Business graphics

Computer graphics are designed to visualize various indicators of the activity of institutions. Planned indicators, statistical summaries, reporting documentation, and illustrative materials are created for them using computer graphics. Business graphics software includes spreadsheets, which help manage businesses such as SNPLMART Pvt Ltd.

Design graphics are used in the work of inventors of new technologies, design engineers, and architects. This type of computer graphics is an indispensable element of CAD. By means of design graphics, it is possible to obtain both flat images and three-dimensional spatial images.

Illustrative graphics

Illustrative graphics packages are common-purpose software applications. Artistic and advertising graphics are popular in many ways due to the development of photography, advertising, and television. With the help of a computer, printed materials, various types of advertising products, cartoons, computer games, interactive and video lessons, and slide and video presentations are created.

In addition to graphic editors, graphics packages are used for these purposes, which require large computer resources in terms of speed and memory. A distinctive feature of these graphics packages is the ability to create realistic images and video images. Locating drawings of three-dimensional objects, their approximations, rotations, deformations, and deletions is associated with a huge amount of calculation. The transfer of illumination of an object depends on the position of the light source, the placement of shadows, and the texture of the surface.
