Color Models in Computer Graphics Donald Hearn Book:

Computer graphics is an art of drawing pictures on computer screens with the help of programming. It involves computations, creation, and manipulation of data. In other words, we can say that computer graphics is a rendering tool for the generation and manipulation of images.

Cathode Ray Tube

First concept of Computer Graphics is the primary output device in a graphical system is the video monitor. The main element of a video monitor is the Cathode Ray Tube (CRT), shown in the following illustration.

Solution Of Computer Graphics By Donald Hearn:

The operation of CRT is very simple −

  • Computer Graphics With Opengl 4th Edition Book The electron gun emits a beam of electrons (cathode rays).
  • Computer Graphics With Opengl 3rd Edition By Donald Hearn And Pauline Baker The electron beam passes through focusing and deflection systems that direct it towards specified positions on the phosphor-coated screen.
  • Computer Graphics With Opengl 4th Edition  Book When the beam hits the screen, the phosphor emits a small spot of light at each position contacted by the electron beam.
  • Computer Graphics With Opengl 3rd Edition By Donald Hearn And Pauline Baker It redraws the picture by directing the electron beam back over the same screen points quickly.

Computer Graphics With Opengl 4th Edition Book Concept

There are two ways (Random scan and Raster scan) by which we can display an object on the screen.

Raster Scan

Computer Graphics By Donald Hearn And Pauline Baker Second Edition Book Concept is In a raster scan system, the electron beam is swept across the screen, one row at a time from top to bottom. As the electron beam moves across each row, the beam intensity is turned on and off to create a pattern of illuminated spots.

Computer Graphics By Donald Hearn And Pauline Baker Second Edition Picture definition is stored in memory area called the Refresh Buffer or Frame Buffer. This memory area holds the set of intensity values for all the screen points. Cs6504 Computer Graphics Lecture Notes Stored intensity values are then retrieved from the refresh buffer and “painted” on the screen one row (scan line) at a time as shown in the following illustration.

Computer Graphics Donald Hearn And M Pauline Baker Book:

Computer Graphics By Donald Hearn And Pauline Baker Second Edition Book Each screen point is referred to as a pixel (picture element) or pel. Cs6504 Computer Graphics Lecture Notes At the end of each scan line, the electron beam returns to the left side of the screen to begin displaying the next scan line.

Random Scan (Vector Scan)

cs6504 computer graphics Book Picture definition is stored as a set of line-drawing commands in an area of memory referred to as the refresh display file. Cs6504 Computer Graphics Book To display a specified picture, the system cycles through the set of commands in the display file, drawing each component line in turn. cs6504 computer graphics Book syllabus After all the line-drawing commands are processed, the system cycles back to the first line command in the list.
