April 20th - 22nd, 2015, in Smolenice, Slovakia

We received a large number of submissions in reply to the Call for Participation of CESCG 2015. Thus, we are proud to publish the preliminary program of CESCG 2015. The final program will be published on April 07, 2015

We were able to provide full presentation slots to all submissions. Even more, four student papers which were originally submitted to the CESCG were accepted for the SCCG and will be presented within the joint day. We are also preparing a series of workshops to improve your writing and presentation skills. These are meant to promote scientific careers and academic mobility within the Visegrad region.

In order to sucessfully prepare for the seminar, please do not forget to take care of the following:

Please follow all comments and try to include all requests of the reviewers in the camera-ready version of your paper. Your local supervisor should assist you and check the final pdf before submitting. Please note that we also require you to submit the LaTEX source in a zip file, so that we may adjust and compile it easily in case of any formatting issues.
Supplementary material
Along with the paper, we will be happy if you can also include a web presentation or some screenshots, sourcecode, datasets etc.
You should prepare and practice your presentation with your supervisor at least a week in advance. We also offer feedback to your slides if you upload them on April 11, 2015 the latest.
The fast-forward session will provide a quick preview of all the papers and is obligatory for all speakers. Please send us your 30 seconds presentation or video until April 13, 2015.
We hope that you can also show us a video about your research - either explaining the principles of the theory or presenting how the application works. We will award the best video at the closing ceremony.
The detailed timetable will all deadlines can be found at the bottom of Call for Participation.

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 15, 2015, 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 March 11, 2015. Final submissions must be uploaded by April 04, 2015, 23:59 CET at the latest. Submissions which are uploaded after this deadline cannot be published in the printed version of CESCG 2015 proceedings.

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 note that the templates have been updated for this year. Please use the latest version and submit the LaTeX source as well.

Please also make sure that all participants of CESCG 2015, esp. the speakers and supervisors, do register as early as possible via the registration page!

Preliminary Seminar Schedule

The seminar schedule is again divided into three days. We have two invited talks sessions, six paper sessions, coffee breaks and lunch and again very popular social programs.

Invited Talks

The organizers of CESCG 2015 are proud to announce the invited talks to be held at the seminar:

Invited Speaker Title and Abstract
Computational Challenges in Designing Virtual Models for Fabrication

3D printing is considered a disruptive technology with potentially tremendous socioeconomic impact. In recent years, additive manufacturing technologies have made significant progress in terms of both sophistication and price; they have advanced to a point where devices now feature high-resolution, full-color, and multi-material printing. Nonetheless, they remain of limited use, given the lack of efficient algorithms and intuitive tools that can be used to design and model 3D-printable content. My vision is to unleash the full potential of 3D printing technology with the help of computational methods. In our research, we are working to invent and develop new computational techniques for intuitively designing virtual 3D models and bringing them to the real world. Given the digital nature of the process, three factors play a central role: computational models and efficient representations that facilitate intuitive design, accurate and fast simulation techniques, and intuitive authoring tools for physically realizable objects and materials. In this talk, I will present several projects that demonstrate our recent efforts in working toward this goal, structured according to basic object properties, and the lessons learned from working over several years with various 3D printers.

Bibliographical Details

Bernd Bickel joined IST Austria in early 2015 as Assistant Professor. He is a computer scientist interested in computer graphics and its overlap into animation, biomechanics, material science, and digital fabrication. His main objective is to push the boundaries of how digital content can be efficiently created, simulated, and reproduced.

Bernd obtained his Master’s degree in Computer Science from ETH Zurich in 2006. For his PhD studies, Bernd joined the group of Markus Gross who is a full professor of Computer Science at ETH Zurich and the director of Disney Research Zurich. From 2011-2012, Bernd was a visiting professor at TU Berlin, and in 2012 he became a research scientist and research group leader at Disney Research, where he investigates approaches for simulating, designing, and fabricating materials and 3D objects.

Bernd’s work focuses on two closely related challenges: (1) developing novel modeling and simulation methods, and (2) investigating efficient representation and editing algorithms for materials and functional objects. Recent work includes: theoretical foundations and practical algorithms for measuring and modeling the deformation behavior of soft tissue; simulating and reproducing fundamental properties, such as elasticity, surface reflectance, and subsurface scattering; and computational design systems for efficiently creating functional artifacts such as deformable objects and mechanical systems.

Challenges in Digital Shape Reconstruction

Digital Shape Reconstruction is a rapidly expanding new technology to produce complex digital models from measured data. A wide variety of applications emerges in mechanical engineering, medical sciences, and preserving the cultural heritage of mankind.

This talk focuses on reproducing engineering objects and investigates the limits of creating perfect CAD models in a semi-automatic manner. It gives an overview of the whole DSR process from 3D data acquisition through algorithms to reproduce the original design intent to 3D printing. Intermediate geometric processing steps include merging point clouds, repairing and simplifying meshes, segmentation, classifying surface regions, fitting surfaces and perfecting the final models before these are exported into CAD/CAM systems. Some interesting algorithmic details will also be discussed. The talk will be supplemented with lots of short videos that will help to gain some practical insight into this highly complex, interdisciplinary area.

Bibliographical Details

Dr. Tamas Varady led the Geometric Modeling Laboratory at the Computer and Automation Institute of the Hungarian Academy of Sciences for 20 years (1984 - 2003). He acted as Chief Technology Advisor for Geomagic, Inc., USA, and partly directed the development of their flagship product, Geomagic Studio (2003 - 2010). Currently he is a full professor at the Budapest University of Technology and Economics; his research interest includes digital shape reconstruction and surface modeling based on general topology curve networks. Dr. Varady has published more than 90 research papers, and his work is highly cited (2500+). He is an associate editor of Computer-Aided Geometric Design (Elsevier).
