Di/Tue 10:00 - 11:30 + Do/Thu 15:15 - 16:45 (V), Di/Tue 13:30 - 15:00 + Mi/Wed 13:30 - 15:00 (Ü)


The course consists of two parts: In the part on computer graphics an introduction to Computer Graphics is given. The hardware oriented language OpenGl is used to describe the rasterization pipeline. This pipeline allows to efficiently transform geometric 3D data into raster images.

  • preprocessing of the data (transformation, projection, clipping)
  • rasterization (scan-line algorithms, z-buffer)
  • shading methods (Gourand shading, Phong shading)
  • local vs. global illumination
  • Raytracing, Radiosity and image-based rendering
  • texuring methods
In the part interacitve systems a broad overview about the goals and research topics of the scientific discipline Human-Computer Interaction is given. They will achieve a basical understanding of developing interactive products while taking user and task requirements in account. Aim of this development process is the design of usable products, that enhance the joy of use. Therefore, basic design principals, methods and tools are presented and intensified in practical exercises. Because of the course's character as basic course only an overview can be given of the comprehensive and strong interdisciplinary field of Human-Computer Interaction (connected to computer science, design, psychology, ergonomics, education science etc.). Interested students get the possibility to intensify their studies by visiting continuative courses like Usability Engineering Design and Evaluation or Visual Seeking Systems.






Examination: written examination of 120 minutes duration Successful participation in the practical exercises is mandatory for the authorization to the written examination. Grade: grade of the written examination
