1. Computers have become powerful tools for the rapid and economic production of pictures. Computer graphics is one of the most rapidly growing fields in computer science. It is used routinely in such areas as business, industry, art, government, education, research, training, and medicine.
2. One of the uses of computer graphics is as an aid to design, generally referred to as computer-aided design (CAD). One of its greatest advantages is that designers can see how an object will look after construction and make changes freely and much more quickly than with hand drafting. For three-dimensional rendering of machine parts, engineers now rely mostly on CAD. Automobile, spacecraft, aerospace and ship designers use CAD techniques to design vehicles and test their performance. Building designs are also created with computer graphics systems. Architects can design a building layout, create a three-dimensional model, and even go for a "walk" through the rooms or around the outside of the building.
3. Business graphics is another rapidly growing area of computer graphics, where it is used to create graphs, charts, and models to summarize financial, statistical, mathematical, scientific, and economic data. As an educational aid, computer graphics can be used to create weather maps and cartographic materials. Computer art also has creative and commercial art applications, where it is used in advertising, publishing and film productions, particularly for computer animation.
