In other words, we can say that computer graphics is a rendering tool for the generation and manipulation of images. Cathode Ray Tube The primary output device in a graphical system is the video monitor. The main element of a video monitor is the Cathode Ray Tube C R T , shown in the following illustration. The operation of CRT is very simple − The electron gun emits a beam of electrons c a t h o d e r a y s . The electron beam passes through focusing and deflection systems that direct it towards specified positions on the phosphor-coated screen. When the beam hits the screen, the phosphor emits a small spot of light at each position contacted by the electron beam. It redraws the picture by directing the electron beam back over the same screen points quickly. There are two ways R a n d
