April 20th - 22nd, 2009, Budmerice Castle, Slovakia

Up to December, we received a large number of announcements of participation in reply to the Call for Participation of CESCG 2009. Thus, we are proud to publish the preliminary program of CESCG 2009.

Unfortunately, we were not able to accomodate all requested slots, but we have tried to make a fair selection. Please have a look at the list of talks below and send us as soon as possible the information still missing in the table (names, talk titles).

To prepare the successful preparation of printed proceedings and web proceedings for the seminar, we want to remind the participants about how to proceed in preparing their contributions. The detailed timetable can be found in the Call for Participation. Please note that in 2006 there were some changes to the LaTEX template, as well as new instructions for providing images, so please review them carefully!

A Note to Participants

Participants are required to upload a zipped version of their submission (including possible supplementary material like additional images, movies, ..., for reviewing) via our submission web page by February 2, 2009, 23:59 CET at the latest. Note that also this year we do not require an anonymous version. The material will then be distributed for reviewing. Reviews will be sent to the authors by February 23. Final submissions must be uploaded by March 13, 2009, 23:59 CET at the latest. Submissions which are uploaded after this deadline cannot be published in the printed version of CESCG 2009 proceedings. As the HTML version of the proceedings will be prepared in parallel with their printed version, the HTML files have to be here by the same deadline as well.

Please read the upload instructions which are available at our submission web page carefully, such that we have no problems to include all the contributions in the proceedings. Please recall that only those contributions are included in any form of seminar proceedings that conform to the "Guidelines for Authors" as specified at!

Please also make sure that all participants of CESCG 2009, esp. the speakers and supervisors, do register as early as possible via the registration page!

Invited Talks

The organizers of CESCG 2009 are proud to announce the invited talks to be held at the seminar:

Invited Speaker Title and Abstract
Helwig HAUSER,
Interactive Visual Data Exploration and Selected Applications

Visualization aims at establishing a bridge between users and their data -- tasks such as data exploration, visual analysis, and the presentation of findings are supported. Especially in the context of data exploration and analysis, interaction plays a crucial role in visualization. In this talk, a matured concept of interactive visual data exploration is presented that proved its usefulness in a series of different applications. Multiple, linked views are used to show different aspects of the same data, brushing is used to annotate the data with degree of interest values (to incorportate a notion of interpretation in the approach). Focus+context visualization allows to see features in relation to all the data. Data derivation proves as a powerful extension to achieve higher-level exploration and analysis. Application examples include the exploration/analysis of data from automotive engineering, meteorological data, and medical data.

Computer-Assisted Engineering of Biomolecules

Bioinformatics is the information technology applied to the management and analysis of biological data. Analysis of the tertiary structures of biomolecules experimentally determined to the atomic resolution provides insight into the function of living organisms, which is useful for example in designing and optimization of biomolecules for industrial applications. A number of computational tools have been developed for storage and analysis of biomolecular structures in recent years. Yet, new tools are needed for prediction of changes in a structure that will result in modification of the function in a controlled manner. Predicted changes, called mutations, can be then introduced into the structures by the molecular biology techniques. The lecture will describe the usefulness of bioinformatics for design and construction of proteins with novel properties. Presented will be a general concept of computer-assisted engineering of proteins as well as two in-house programs CAVER and HOTSPOT WIZARD developed for prediction of mutations. Examples will be given from engineering of proteins for synthesis of fine chemicals and for detoxification of dangerous chemical substances.

For the first time this year, there will be also a special industry session held by our sponsor Autodesk:

Keynote Speaker Title and Abstract
Stephen STOTT,
United Kingdom
Creativity and Imagination - Inspiration to Digital Solutions

The ability to generate ideas can be developed through exposing students and teachers to a framework of creative learning strategies. This presentation describes a pedagogy that encourages individuals to explore the diversity of imagery and objects from the natural and built world as the stimulus to evolve new and innovative solutions to design problems. The learner will be introduced to skills to guide them to "deconstruct" a source of inspiration and identify key functional and aesthetic elements that will influence the development of a valid engineering outcome. The use of traditional methods of visualisation is explored through pencil drawing and sculptural models and developed into computer aided design through using Autodesk Inventor to create three dimensional digital prototypes.
