Lecture Course: Interactive Computer Graphics, Summer Term 2023

The students will get to know basic concepts and algorithms of computer graphics. They will be able to fruitfully adopt them to their own graphic applications. This includes polygonal models, texturing, and illumination techniques. Furthermore, all conceptual phases of the rendering pipeline as fundamental steps to image synthesis will be trained. Thus, the students will have the means to apply on CPU and GPU widely used graphics algorithms.

The lecture introduces basic concepts of realtime computer graphics as it is used e.g. in computer games. We focus on the rendering pipeline as a conceptual foundation of modern systems to image synthesis. The considered algorithms will be introduced and discussed in theory first. A selection of algorithms will also applied in practice during the exercises. The application uses C/C++ combined with the graphics API OpenGL.

The following issues are dealt with in particular:

• Graphics programming in OpenGL
• Geometric transformations and projections
• Calculating illumination
• Clipping algorithms
• Rasterization and texturing
• Geometric modelling

The exercise hours will take place throughout the semester as an integrated part of the lecture. During the exercises we also arrange a rendering contest where students can implement a project.

Please get yourself familiar with the following frameworks:

• GLM - OpenGL Mathematics Library
• GLI - OpenGL Image Library
• GLFW - Canvas and Input Handling Library
