These were largely supplanted by raster-based devices in the following decades. For these reasons, documents and illustrations are often stored or transmitted as 2D graphic files.ĢD computer graphics started in the 1950s, based on vector graphics devices. This representation is also more flexible since it can be rendered at different resolutions to suit different output devices. In many domains, such as desktop publishing, engineering, and business, a description of a document based on 2D computer graphics techniques can be much smaller than the corresponding digital image-often by a factor of 1/1000 or more. 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). It may refer to the branch of computer science that comprises such techniques or to the models themselves.ĢD 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. ( Learn how and when to remove this template message)ĢD computer graphics is 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.
