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, as well as for 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, built on the basis of an array of lamps, it was possible to obtain patterns.
Digital graphics applications
The first computers were used only for solving scientific and industrial problems. In order to better represent the obtained results, 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. Up-to-the-minute scientific computer graphics make it possible to perform computational experiments with a visual presentation of their results.
Computer graphics areas are designed to visualize various indicators of the activity of institutions. Planned indicators, statistical summaries, and reporting documentation, illustrative materials are made for them using computer graphics. Business graphics software includes spreadsheets. This helps 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 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.
