Leif Kobbelt

Leif Kobbelt is a full professor of computer science and chair of the computer graphics group at RWTH Aachen University, Germany. His research interests include geometry processing, 3D geometry acquisition, computer vision, as well as mobile multimedia and interactive visualization.

Leif Kobbelt completed his PhD at the University of Karlsruhe in 1994. After a postdoc stay at the University of Wisconsin in Madison (with Carl de Boor) he joined the Computer Graphics group at the University of Erlangen in 1996 and completed his Habilitation in 1999. Shortly after joining MPI Informatik as an associate professor in 1999, he received an offer for a full professorship from RWTH Aachen University and moved to Aachen in 2001.

Leif Kobbelt’s early work focused on subdivision surfaces where he made several fundamental contributions, including his algorithm for interpolatory subdivision on quad nets with arbitrary topology (Eurographics 1996), his well-known Sqrt(3) subdivision algorithm (SIGGRAPH 2000), and a significant body of pioneering work on variational subdivision and discrete fairing. With the advent of 3D scanner technology, the acquisition and processing of very large unstructured 3D data sets has become an important topic of research with high practical relevance, and Kobbelt’s work has significantly influenced the state of the art: Ideas from subdivision and mesh decimation paved the way for powerful multiresolution techniques and Kobbelt’s SIGGRAPH 1998 paper on interactive multi resolution modeling on arbitrary meshes is one of the most widely cited milestones in this development. Other important contributions are his work on remeshing (e.g. Eurographics 1999, Günther Enderle Award), on feature sensitive surface extraction (SIGGRAPH 2001), and on shape modeling with point sampled geometry (SIGGRAPH 2003).

Leif Kobbelt’s work combines sound mathematical analysis with a thorough understanding of the relevant problems, and significant implementations. His results have helped to shape the newly emerging field of 3D geometry processing. Based on his initiative the Symposium on Geometry Processing Series started in 2003. Within the German Gesellschaft für Informatik he is founding chair of the special interest group on geometry processing.

Leif Kobbelt has chaired several leading international events and served on many international program committees (including Eurographics, SIGGRAPH). His research contributions have been recognized and cited widely, and he received several awards for his work, including the Heinz-Maier-Leibnitz Award from the German Research Foundation (DFG) in 2000 and the first Eurographics Outstanding Technical Contributions Award in 2004.

Leif Kobbelt was elected to a Fellowship of the Association in recognition of:

  • his research contributions to computer graphics and geometry processing;
  • his contributions towards setting up the symposium on geometry processing series and turning it into a leading international event;
  • his chairmanship of several leading international events.

László Szirmay-Kalos

László Szirmay-Kalos is a full professor of computer science and head of the Department of Control Engineering and Information Technology at the Budapest University of Technology and Economics, Hungary. His research interests include photorealistic image synthesis, global illumination with Monte Carlo techniques, optical material models and BRDFs, scientific visualization, and implementations on computer graphics hardware.

László Szirmay-Kalos completed his PhD in Computer Science at the Hungarian Academy of Sciences in 1992. He got a position at the Budapest University of Technology and Economics, where he started a new computer graphics group. In 2001 he became a full professor at this university.

He participated in large scale software development projects which resulted in global illumination and real-time rendering systems. During the last 5 years he led more than 10 research projects. He has written several books and more than 150 scientific papers on realistic rendering.

László Szirmay-Kalos’s early work focused on global solutions for the radiosity calculation, investigating convergence properties and complexity measures of such algorithms. Making use of stochastic methods, in particular of Monte Carlo like algorithms, he managed to improve the runtime of such algorithms dramatically over the years. Other research fields in the late 1990’s were ray shooting algorithms and stochastic reflectance models. With the development of powerful graphics cards László invented various methods to speed up algorithms not only for global illumination, but also for shading, shadows, displacement mapping, and volume visualization.

One of the best graphics textbooks is “Theory of Three Dimensional Computer Graphics” (by László Szirmay-Kalos), which first appeared in 1995. His new book “GPU-Based Techniques for Global Illumination Effects” (co-authored by László Szécsi and Mateu Sbert) summarizes many of the useful results he obtained in the last years. Unfortunately, some of his other books are available only in Hungarian, which on the other hand helped to boost the Hungarian graphics landscape a lot.

László Szirmay-Kalos’s work is characterized by sound mathematical analysis with a thorough understanding of the relevant problems, and significant implementations. His writing style is excellent and so his books are first class comprehensions of the field. His contributions have been recognized and cited widely, and he received several awards for his work, including a third best paper award at Eurographics 1999.

László Szirmay-Kalos was elected to a Fellowship of the Association in recognition of:

  • his research contributions to computer graphics, especially in the field of Monte Carlo global illumination;
  • his contributions to Eurographics, including his roles as co-chairman of the IPC in the Eurographics ’97 event in Budapest (the first time the conference had been held in Eastern Europe), and the Eurographics 2006 event in Vienna;
  • the establishment of a strong computer graphics group at the Technical University of Budapest.
