Introduction to computer graphics and animation

Computer graphics appeared long ago – in the 1960s there were full-fledged graphic systems alredy. Today we are using computer graphics (CG) and computer animation (CA) terms. The concept of computer graphics includes all kinds of work with static images, computer animation deals with dynamically changing images. Combine graphics and animation allows the abbreviation of CG&A.

Computer graphics – input, output, display, transformation and editing of graphic objects under the control of a computer.

Computer animation – making images alive on the display screen, the synthesis of dynamic images on the computer.

No matter how rich the softwer for raster CG&A is, a significant part of the working on image building should be done manually, including drawing intermediate frames in the animation. In this regard, raster packages can be attributed to the means of computer painting. And the current 3D image is easier to create with the help of vector graphics: its technology allows giving instructions (commands) to the computer, guided by which it builds images with the help of algorithms embedded in the program. This method is more like drawing, and often three-dimensional.
