The Course in a Nutshell

  • Credits: 6 (ECTS)
  • Wednesdays, 11:00 – 12:45, S1.11

Fridays, 15:30 – 17:15, S1.11

  • Book: E.Angel Interactive Computer Graphics

5th Ed., Addison Wesley, 2008 get it from STORM or the VU Boekhandel (4th Ed. is considered “good enough”)

  • Grading: written exam (1/3) plus programming assignments (2/3)

both parts must be graded “sufficient”

Programming Assignments

  • Organized by: Asia Slowinska and Ana Oprescu
  • Programming in C++ (or C) with OpenGL
  • Programming on Windows PC’s of FEW/CS:

(or on your own PC, but programs must run on our Windows platform)

  • Details via the WWW page:

http://www.cs.vu.nl/˜graphics/ The assignments:

  • Exercise 1: “the basics”
  • Exercise 2: “pickup truck”
  • Final project:

⋆ Dino, Pony, Cat, Grasshopper ⋆ or use your own models

And now for “Computer Graphics”. . .

  • Where do we find computer graphics?

⋆ display of information (scientific visualization) ⋆ design ⋆ simulation ⋆ user interfaces ⋆ games, of course

The Liquid Crystal Display (LCD)

  • Thin Film Transistor (TFT) display
  • uses matrix of transistors
  • TFT’s make color filters more or less transparent
