Basic Data

  • Bachelor/Master of Computer Science @ Uni Marburg: Module name: CS 581 (9 credit points)
  • Master of Math @ Uni Marburg: selectable module

Objectives of the Course

  • Acquire knowledge for creating interactive computer graphics applications
  • Learn basic concepts of computer graphics
  • Gain experience in practice-oriented programming environments
  • Improve the ability to perform scientific work and to solve problems
  • Create complete computer graphics projects independently

Course Structure

  1. Introduction
  2. Graphical user interfaces (skipped this year)
  3. Representation and rendering of 2D objects
  4. OpenGL pipeline
  5. Object transformations
  6. Cameras
  7. Textures
  8. Buffer Objects
  9. OpenGL Shading Language (GLSL)
  10. Light and materials
  11. Shadows and reflections
  12. Game Programming

Programming environment

  • Focus on rasterization methods
  • OpenGL is used as a graphics library
  • GLSL as a shader language
  • OpenGL / GLSL programming independently of the GUI framework used
  • GUI-Framework: Java (Desktop and Android) or alternatively in C++
  • GUIs are nowadays often implemented using web technologies, hence HTML/Java-Script/WebGL

Organizational matters

  • The course consists of a lecture (4 hours per week) and an exercise (2 hours per week).
  • Lecture: Mon 14h00 - 15h30, Fri 10h15 - 11h45, MZ 6 HS III A3
  • Exercise: Montags after the lecture, MZ 6 HS III A3
    Start: October 30, 2023

Material for the lecture

  • Website:
  • Slides are available in HTML5 format
  • In Google Chrome, the browser's print function can be used to create a PDF file of the slides
  • The slides might be updated before the lecture (or also shortly afterwards)
  • Two versions of the slides: internal and external
  • The internal slides are more comprehensive
  • To access the internal slides a login is required

Exercises

  • Register for the exercise groups via the e-learning-plattform ILIAS (from Oct 16, 2023, 14h00 till Oct 24, 12h00)
  • Individual submission of assignments (no group work)
  • Tutor: Sebastian Lieb, Lennart Uhrmacher
  • Content: 80% practical part (programming assignments), and 20% theoretical part (questions)
  • Requirements for certificate/module examination:
    • 50% of the exercise points
    • No more than two exercise sheets not submitted (0 points = not submitted)
    • Regular participation in the exercise class
  • The exercise sheets are made available every Friday around 12h00 on the website for the lecture and on ILIAS
  • The first exercise sheet will be available on October, 27, 2023
  • Submission must occur on every Friday 12h00 by an E-mail (PDF or text) to your tutor
