    • Computer Graphics – What’s It All About?
    • Application Areas
    • Course Outline

    • Exams & CA
    • Books
    • Miscellanea
    • Questions?
  • 3. What Is Computer Graphics?
    • The term computer graphics was coined in 1960 by William Fetter to describe new design methods he was pursuing at Boeing
    Fetter created a series of widely reproduced images on a pen plotter exploring cockpit design, using a 3D model of a human body
  • 4. What Is Computer Graphics? (cont…)
    • “ Perhaps the best way to define computer graphics is to find out what it is not. It is not a machine. It is not a computer, nor a group of computer programs. It is not the know-how of a graphic designer, a programmer, a writer, a motion picture specialist, or a reproduction specialist.
    • Computer graphics is all these – a consciously managed and documented technology directed toward communicating information accurately and descriptively.”
    • Computer Graphics , by William A. Fetter, 1966
  • 5. Interactive Computer Graphics
    • Takes things a step further by allowing users rapid visual feedback from their actions
    • Typically we have the following cycle:
    • This area is the focus of this course
    INPUT PROCESSING DISPLAY/ OUTPUT Mouse Tablet and stylus Force feedback device Scanner Live video streams Screen Paper-based printer Video recorder Projector VR/AR headset
  • 6. Interactive Computer Graphics (cont…)
    • Sketchpad, developed in the 1960s, was the first interactive computer graphics application
    • Using a light pen, key pad and monitor it allowed users create accurate design drawings
    Dr. Ivan E. Sutherland developed Sketchpad as part of his PhD work. He went on to be a hugely influential computer scientist working in areas as diverse as graphics, circuit design, robotics and computer hardware
  • 7. So?
    • If we add interactivity, Fetter’s definition pretty much still holds
    • So much of modern computing involves some graphical aspect that computer graphics is now ubiquitous
    • So let’s say computer graphics encompasses anything achieved visually on computers
  • 8. Some Applications Of Computer Graphics
    • Some of the application areas which make heavy use of computer graphics are:
      • Computer aided design
      • Scientific visualisation
      • Films
      • Games
      • Virtual/Augmented Reality
    • NOTE: There are lots more and there is huge overlap between these different areas
  • 9. Computer Aided Design
  • 10. Scientific Visualisation
  • 11. Films
  • 12. Games
  • 13. Virtual/Augmented Reality
  • 14. Course Outline
    • The course will follow this broad-strokes outline:
      • Maths Preliminaries
      • Viewing in 2D
      • Raster Graphics
      • Viewing in 3D
      • 3D Object Modelling
      • Illumination and Surface Rendering
      • Animation
    Practical Work in OpenGL
  • 15. Lectures & Labs
    • Lectures:
      • Thursday 13:00 – 14:00
      • Friday 15:00 – 16:00
    • Labs:
      • Wednesday 10:00 – 11:00
      • Wednesday 17:00 – 18:00
    ATTEND THE LABS!!!
  • 16. Exams & CA
    • Exams:
      • Part A of end of year exam will cover all theoretical material
    • CA:
      • Marks awarded for completing each lab exercise
      • Two significant graphics projects using OpenGL
  • 17. Books
    • “ Computer Graphics with OpenGL”, D. Hearn & M. P. Baker, Prentice Hall, 2003 Most of the course follows this book
    “ Introduction to Computer Graphics”, J.D. Foley, A. van Dam, S.K. Feiner, J.F. Hughes & R.L. Phillips, Addison Wesley, 1997 “ Computer Graphics: Principles and Practice”, J.D. Foley, A. van Dam, S.K. Feiner & J.F. Hughes, Addison Wesley, 1995 Great for really in-depth theory
