Welcome to CESCG 2007!

CESCG, the Central European Seminar on Computer Graphics, is entering a new decade! After the wonderful festivities last year celebrating the 10th anniversary of CESCG, we are off for a fresh start and looking for new challenges in a new decade!

The long history of CESCG has started in 1997 in a medium-sized lecture room in Bratislava, bringing together students from Bratislava, Brno, Budapest, Graz, Prague, and Vienna. The idea found wide appraisal and the seminar moved to the beautiful castle of Budmerice, where it was held for 8 consecutive years, constantly growing in size and attraction. It was just in the 10th anniversary year 2006 that CESCG had to take a detour to move to Častá-Papiernička Centre. Although this proved a more than adequate venue, we are happy that the new decade of CESCG sees us back in Budmerice castle, which we have grown to love so much!

Who are the CESCG heroes who made this year's seminar happen? In no particular order -- because many people were involved equally -- we would like to thank the organizers from Vienna, especially Stefan Jeschke for taking care of the complete reviewing process. We are very thankful to the CESCG organizers from Bratislava, mainly Andrej Ferko, always an inspiration to CESCG; and Stanislav Stanek, Roman Durikovič, Zdenka Slobodová, Martin Samuelčík and Pavla Ňuňuková for the excellent preparations and on-site organization.

The main idea of CESCG is to bring students of computer graphics together across boundaries of universities and countries. Therefore we are proud to state that we have achieved again a very high number of 16 participating institutions and a very tight time schedule of 24 valuable student works and two invited talks. We are also proud that for the first time, students from Freiburg University, Germany, joined the seminar. We also welcome groups from Bratislava (UK and STU), Slovakia; Brno, Plzeň and Prague, Czech Republic; Budapest, Hungary; Bonn, Germany; Graz, Hagenberg and Vienna (TU and VRVis), Austria; Szczecin, Poland; Maribor, Slovenia; and Sarajevo (Univ. and SST), Bosnia and Herzegovina.

Due to the positive experience with an enlarged program committee established last year, we again assembled a large International Program Committee of 14 members. This allowed us to have each paper reviewed by two IPC members during the informal reviewing process. We would like to thank the members of the IPC for their contribution to the reviewing process. The IPC of CESCG 2007 consists of:

Andrej FerkoMartin Šperka
Markus GrabnerMichael Wimmer
Helwig HauserPavel Zemcík
Reinhard KleinBorut Žalik
Ivana KolingerováJiří Bittner

Invited talks this year are held by Ivana Kolingerová from the University of West Bohemia, Czech Republic, about Triangulations for Computer Graphics Applications, and Mateu Sbert from the University of Girona, Spain, about Applications of Information Theory to Computer Graphics. The seminar features an exhibition Aesthetics in Computation organized by Peter Borovský. The seminar is held under the auspices of the Austrian Ambassador to Slovakia, His Excellency Dr. Helmut Wessely, and is co-organized with the Spring Conference on Computer Graphics (SCCG), which takes place right after the seminar.

The organization of a seminar where there are de facto no expenses for the students requires funding. We are very thankful to the sponsors of CESCG 2007:

  • Ministry of Education of the Slovak Republic;
  • SOFTIP, a Slovak information technology provider;
  • NOKIA, connecting people;
  • Eurographics, the European Association for Computer Graphics;
  • VRVis, a research center for virtual reality and visualization in Vienna;
  • A K Peters, a publisher of scientific books;
  • Caligari Corporation, 3D modeling and rendering software;
