What are Computer Graphics?

Computer graphics are pictures produced by computer. They may appear on screen or be printed on paper. Almost all the computer games and now business, scientific and engineering programs use graphics. The graphics with their colour and drawings prove to be more informative than when explained in words. The use of graphics in Computer Aided Design (CAD) can help in designing a small object to a space craft. Engineers use computers in the designing of more efficient vehicles. Small changes can be made to the design and their effects can be observed without having to redraw the whole object and make a new model for testing.
