the process of object planning, the additional programs will be able to conduct treatment of project
database with the purpose of preparation, necessary on the different stages of making the object of
technical documentation, such as complete sets of designer and technological documentation.
Design and making of animated cartoon
Animation made with the help of computer and demonstrate the conduct of various real or
modeled objects in time become more popular. They allow to learn the mathematical models of the
most various phenomena which are examined by science, for example, the flow liquids, nuclear and
chemical reactions, physiology systems and deformation of constructions on-loading, by visual
presentation of model’s conduct under various conditions. Various trainers are the second use of the
computer making animated cartoon. They allow to generate not only the immobile world where an
object moves but also such special effects, as clouds, fog, smog, nightly fires, and also other objects
of the most various shapes and sizes which move due to their course. Computer graphics is widely
used in the creation of feature films and publicity video, saturated 3D-effects.
Management processes
If trainers enable the user to socialize with the model of the actual or imaginary world, there is
a necessity to work in the interactive mode directly with some aspects of the real world in many
cases. Displays at the oil-processing factories, power-stations or at any other productions allow to
imagine visually information from the sensing elements placed in the most essential points of the
system. Such reflection of information allows to operate different processes quicker and more
effective.
Automation of office works and electronic publication
Computer graphics for forming and distribution of information in administrative
establishments is being widely used. It helps it is possible to make traditional printing documents
(hard copy), "electronic" documents which consist not only of phototypography but also tables,
graphs and other illustrative two-dimensional information.
Art and advertising
The joint aim of computer art and advertising is a desire facilities of computer graphics to
express the main content of depiction by means of computer graphics and a desire to pay attention
to it by aesthetically pleasant depictions. One of the most modern and economically effective mean
of the use of computer graphics in this field is making of sliding seats for presentation of
commercial, scientific and educational information.

9.3 TYPES OF COMPUTER GRAPHICS

Three basic principles of presentation of graphic images – bit-mapped graphics, vector and
fractal graphics are developed and successfully used. Mathematical models of images are the basis
of this or another method. For a bit-mapped graphics there is the array (matrix) of numbers which
describe co-ordinates and colour parameters of every point of a picture, for vector graphics there are
mathematical formulas which describe geometrical figures (objects) a picture is formed. Fractal
graphic art operates mathematical formulas too, and they describe not separate geometrics, but a
process of automatic generation of image by equations.
A bit-mapped graphics is applied, mainly, in the development of electronic (multimedia) and
publishing editions. For coding a picture is broken up to small monochrome parts. All colors, used
in an image, are numbered, and for every part the number of its color is written down. Memorizing
the sequence of location of parts and the number of color for every part, it is possible to describe
any picture.
