2D
computer graphics are the computer-based generation of digital images mostly
from two-dimensional models, such as 2D geometric models, text, and digital
images, and by techniques specific to them. The word may stand for the branch
of computer science that comprises such techniques, or for the models
themselves. 2D computer graphics started in the 1950s.
2D
computer graphics are mainly used in applications that were originally
developed upon traditional printing and drawing technologies, such as
typography, cartography, technical drawing, advertising, etc.. In those
applications, the two-dimensional image is not just a representation of a
real-world object, but an independent artifact with added semantic value;
two-dimensional models are therefore preferred, because they give more direct
control of the image than 3D computer graphics, whose approach is more akin to
photography than to typography.
