Why Computer graphics

Graphics is cool

      • I like to see what I’m doing
      • I like to show people what I’m doing

​

Graphics is interesting

      • Involves simulation, algorithms, architecture…

Why should we study Graphics?

Many of the leading scientists through the ages have been “visual thinkers”

    • Leonardo da Vinci
    • Albert Einstein
    • Clerk Maxwell
    • Michael Faraday

What is computer graphics

  • Computer Graphics includes almost everything on computers that is not text or sound.

​

  • 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.

​

  • Creation, Manipulation and Storage of geometric objects (modeling) & their images (rendering).

​

  • Display those images on screens or hardcopy devices.

Computer aided design

  • It refers to the use of computer graphics to design buildings , automobiles, aircraft, watercraft, Space Craft and other products

​

  • CAD Applications allow the designer to work in a multi window environment i.e., different views of the objects can be displayed in multiple windows

​

  • Architects find graphics methods useful to draw floor plans showing the position of rooms, doors, stairs etc

  • Graphics design package provides standard shapes (useful for repeated placements)
  • Animations are also used in CAD applications
  • Realistic displays of architectural design permits simulated “walk” through the rooms (virtual -reality systems)
