• When ever we hear the term pixel the only thing that comes to our mind is image information or dots and many others, but what exactly it is? • So it's very very important to understand the term pixel before moving ahead, so let's see what it means. 1) A pixel or Picture Element is the smallest item of information in an image arranged in 2 dimensional Grid i.e. Rows and Columns as follow: • In above image the rows and columns arrangement is know as grid of 2-dimension and the small box or square contains information about image that you already know that is Pixel . 2) After knowing about that pixel contains information about image right, but you might really think, what kind of information or what form of information it stores? • Let's also see that. 3) Each pixel contains information about colors but only three colors i.e RGB most popular once(Red, Green and Blue). 4) This three colors makes all kind of shades almost required to form or represent an image on screen. 5) Bu

 Let's First see the Hardware commonly used: • Hardware is broadly divided into two class as Input and output device 1) Input device • Touch panels • Light pen • Graphics Tablet • Microphones • Mouse • Image scanner • And many others. 2) Output Device • Cathode Ray Tube(CRT) • Vector Scan Display/Random scan Display • Raster Scan Display • Coloured Monitor • LED, LCD, TFT(Screen) • Printer -> We will see the software of Computer Graphics -> Though their are many software available for computer graphics, let's see the few of them: • Photoshop • Maya 3D • CAD • Corel Draw -> We will see all the output devices in details in further post. * You can leave a comment if you have doubt in it.

 Following are some traditional Input devices commonly used today: 1) Mouse 2) Wheel Mouse 3) Trackball: A ball device that can be rotated from finger 4) Spaceball 5) Joystick 6) Data Gloves 7) Keyboard Keyboard * You can leave a comment if you have doubt in it.

  • Computer graphics are visual representation of data on a monitor. • Computer graphics is used in various Fields like: Industry, Education, Entertainment and many others. • Let's see it one by one application of computer graphics: 1 ) Computer Aided Design (CAD) • Designing components of mechanical, electrical and electronic devices. • Building structures • Automobile parts -> Helps the designer to choose the optimize design with minimum no. of components, smaller size, efficient and cost effective system. •Some CAD software are: TinkerCAD, Creo, CATIA, Inventor and many others.                                  Designing structures in CAD 2 ) Graphical User Interface(GUI) • Interact with application in easier way. -> Components of GUI: ✓ Menus: helps the user to reach the application  ✓ Icons: symbols, represent the option ✓ cursor, Dialog box, Button, Grid, Sketching, 3D Interface, Scroll bars. 3) Education and Training • Computer generated model of physical, financial a

First let's understand what exactly the term 'Computer Graphics' is, if you look closely you would recognize that computer graphics is made of three words:                1) Computer               2) Graphics               3) Pics Let's understand one by one: 1) Computer : You might already know a device capable of doing calculation in fraction of seconds most heard one's, but it's a device capable of doing any particular task. 2) Graphs : Here graphs means Gemotrical shapes.   For example: Here through points you can create a line, curve, rectangle, circle, bar graph, pie chart, and many more. 3) pics : which is pictures in computer graphics it is often termed as image. So now let's define computer graphics: • The art of drawing picture or images through geometrical shapes with the help of computer is known as Computer graphics.                                               OR   • Computer graphics is the branch of computer science that deals with generatin
