Current Topics in Computer Graphics and Geometry Processing

Computer Graphics and Geometry Processing are highly active research fields combining aspects of several areas of practical as well as theoretical Computer Science: For example, compact data structures and efficient algorithms are required for real-time renderings and simulations. The generation of photo-realistic images and visualizations is often derived from physical processes observed in the real world. The area of Geometry Processing is founded on classical results of mathematics and physics and directly reaches into typical engineering contexts. Hence, the topics covered in this seminar are among the most inter-disciplinary research fields in Computer Science.

The conferences with the strongest impact on the graphics world are SIGGRAPH, SIGGRAPH Asia, and Eurographics. In this seminar we will discuss results presented recently at those conferences with a focus on the most interesting and innovative ideas. Participating students have the chance to get familiar with state-of-the-art solutions to problems in Computer Graphics, Geometry Processing, Modeling, and Visualization and will gain interesting insights into the involved techniques.
