COMPUTER GRAPHICS-TECHNOLOGY
Computer graphics is an art of drawing pictures, lines, charts, etc using computers with the help of programming. Computer graphics is made up of number of pixels. Computer graphics deals with the study of technology and techniques for generating and displaying images of natural and synthetic objects. It is an exciting field with a wide range of applications including entertainment, graphical user interfaces, industrial modeling, molecular modeling, surgery planning, virtual reality,
