giúp em với nhé đọc đoạn văn và chọn câu trả lời đúng As computers have become powerful tools for the rapid and economic production of picture, computer graphics has emerged as one of the most rapidly growing in fields in computer science. "It" is used routinely in such diverse areas as business, industry, art, government, education, research, training and medicine. One of the initial uses of computer graphics, and ultimately its greatest use, has been 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 heavily 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 simulated "walk" through the rooms or around the outside of the building. Business graphics is another rapidly growing area of computer graphics, where it is used to create graphs, charts, and cost 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, which is achieved by a sequential process. 1.
