We are proud to announce the ninth Central European Seminar on Computer Graphics for students, to be held in Budmerice (together with SCCG 2005) in early May, 2005. This international seminar is a continuation of CESCG '97, CESCG '98, CESCG '99, CESCG 2000, CESCG 2001, CESCG 2002, CESCG 2003, and CESCG 2004, and previously held joint seminars. CESCG is organized by the Institute of Computer Graphics and Algorithms, Vienna University of Technology, and the Department of Computer Graphics and Image Processing, Comenius University, in Bratislava. The seminar is again organized under the auspices of His Excellency Martin Bolldorf, Austrian ambassador in Slovakia. The main sponsor is SOFTIP company.

We are pleased to invite the following groups (in alphabetical order) to actively participate in CESCG 2005 by sending students to the seminar:

Austria	Graz		Institute for Computer Graphics, Graz University of Technology
	Hagenberg		Media Technology and Design, Upper Austria University of Applied Sciences
	Vienna		Institute of Computer Graphics and Algorithms, Vienna University of Technology
			VRVis Research Center for Virtual Reality and Visualization
Bosnia	Sarajevo		Department of Computer Science, Faculty of Electrical Engineering, University of Sarajevo
Czech Republic	Brno		Department of Computer Graphics and Multimedia, Brno University of Technology
	Plzen		Computer Graphics Group at the Department of Computer Science, University of West Bohemia
	Prague		Computer Graphics Group at the Department of Computer Science and Engineering, Faculty of Electrical Engineering, Czech Technical University
Germany	Bonn		Institute of Computer Science II, Computer Graphics Group, University of Bonn
Hungary	Budapest		Computer Graphics Group at the Department of Process Control, Technical University of Budapest
			Faculty of Informatics, Eötvös Lorand Science University
	Szeged		Department of Applied Informatics, University of Szeged
Poland	Szczecin		Institute of Computer Graphics and Multimedia Systems, Technical University of Szczecin
Slovakia	Bratislava		Department of Computer Graphics and Vision and Department of Algebra, Geometry, and Didactics of Mathematics, Comenius University in Bratislava
			Faculty of Informatics and Information Technology, Slovak University of Technology in Bratislava
Slovenia	Maribor		Laboratory for Geometric Modelling and Multimedia Algorithms, Institute of Computer Science, University of Maribor
Switzerland	Zürich		Department of Computer Science, ETH Zürich
United Kingdom	Bristol		Department of Computer Science, University of Bristol

Please note that active participation with paper and talk must be announced via email to cescg#cg.tuwien.ac.at until December 10, 2004. Otherwise an active participation will not be possible! See below for more details about the procedure of registering presentations at CESCG.

The main idea of CESCG is to bring undergraduate students who are interested in computer graphics together across the borders of universities and countries. The seminar is also intended to be an international event, where students can present their excellent work to other students. Actively participating students are, therefore, required to have studied computer science (or something similar) for at least five or six semesters. Sufficient expertise in giving a talk as well as reasonable knowledge of the English language is also required for active participation.

Of course, the overall topic of CESCG is computer graphics. Specifically, the following fields are covered by the seminar:

• Virtual Reality, Augmented Reality
• Scientific Visualization, Information Visualization
• Rendering and Global Illumination
• Animation, Multimedia, and Internet technologies
• Graphical Human-Computer Interaction
• Geometric Modelling, Computational Geometry
• Simulation and Graphics
• Artistic Rendering
• Image Processing, Computer Vision

CESCG is planned to be held in Budmerice at the beginning of May 2005. Students have enough time to arrive in Budmerice on the first day (in time), even from the distant locations. There are approximately 24 talks (including time for discussions) scheduled for all three days in total. The program of the seminar is divided into morning and afternoon sessions. Time for lunch and coffee breaks is reserved as well. After the first and second day of the seminar, there are social programs in the evening, e.g., going to a pub. There is of course the possibility to sleep in Budmerice.

Papers submitted to CESCG are reviewed by well-known researchers in the field of computer graphics to provide the authors with constructive feedback so they can improve their articles before publication. This means that papers are not rejected due to reviewing, but only recommendations on how to improve the papers are provided. The following International Program Committee (IPC) has been established for CESCG (alphabetically ordered):

• Andrej Ferko, Bratislava
• Helwig Hauser, Vienna
• Laszlo Szirmay-Kalos, Budapest
• Radoslaw Mantiuk, Szczecin
• Jiri Zara, Prague
• Michael Wimmer, Vienna

Again, we will have two very interesting invited talks by

• Reinhard Klein (Germany) and
• Radoslaw Mantiuk (Poland)

The seminar language is English, i.e., CESCG papers are written in English and presentations are also given in English language.

Active participation in the form of a published and presented paper has to follow the following process: first, a certain set of computer graphics groups in Central Europe are invited to participate through the dissemination of this call for participation. Then, until the first deadline, invited groups announce their active participation to the CESCG organization in Vienna via mailto:cescg#cg.tuwien.ac.at: groups tell the number of presentation slots they would like to fill at the seminar (one, two, three, or even more). Due to the limited number of talks at a CESCG seminar (up to 24 talks), only one or two slots per actively participating group can be guaranteed. After the first deadline, and according to the total of all talk announcements, the Vienna part of the CESCG organization compiles a so-called preliminary program, which states which groups can send how many students for active presentations.

Each student has a responsible advisor. Until the second deadline, students prepare their CESCG papers under the supervision of their advisor and submit them for reviewing using the submission system on the CESCG webpage. After reviewing, CESCG students incorporate the reviewers' recommendations for improvements into their papers. It is the responsibility of the student's advisor that this happens properly, so that the hard work invested by the reviewers is not in vain. The advisor (and not the student!) then re-submits the improved paper for final publication. Papers are eventually published in printed form (printed proceedings), electronic form (on CD-ROM and as web proceedings), and as presentations directly at the seminar.

The contributions are submitted in some directly printable format for printed proceedings (preferably PDF, or, if not otherwise possible, zipped device-independent Postscript) and the paper source (LaTeX). To ensure a minimum typographic quality of the seminar proceedings, all submissions have to follow the guidelines for authors available at http://www.cg.tuwien.ac.at/studentwork/CESCG/guidelines/. A LaTeX2e class (implementing these guidelines) can be downloaded from this web- page.

Students are highly encouraged to include additional material in their submissions. This additional material can be images, animations, etc., and should be assembled on an HTML page which will be included in the electronic proceedings on the web and the CD.

Note that only those contributions are included in the seminar proceedings which conform to the guidelines specified above and which are submitted in time according to the schedule of the seminar.

To prepare a successful seminar, it is necessary to coordinate several groups in different countries. It is obvious that this can only work if all the participating groups stick to the schedule of the seminar. The schedule for CESCG 2005 is as follows:

Participation in CESCG 2005 is free for attendees who present a paper or supervise a presenter. Participants who just wish to attend the presentations and discussions are of course also kindly invited. A registration fee of Euro 40,- (to be paid via bank transfer) is requested from such participants.
