Invited Speaker Bios and Abstracts

Dr. Oleg Skipa, Team Leader, CST - Computer Simulation Technology

Title: Mesh generation for electromagnetic design and analysis

Biography: Oleg Skipa works as a Team Leader at the R&D department of CST Computer Simulation Technology AG based in Darmstadt, Germany. His responsibility is the mesh generation technology for electromagnetic and multiphysics simulations. He received the Ph. D. degree in 2004 from Karlsruhe Institute of Technology (KIT), Germany working on numeric simulations of electric fields generated by human heart. Before starting his post-graduate studies in 1999, he obtained the Diploma in Physics from Kiev National Taras Shevchenko University, Ukraine.

Abstract:


Leif Kobbelt, RWTH Aachen University

Title: 3D Model Augmentation: From Quad Meshes to Quad Layouts

Biography: Leif Kobbelt is a university professor of Computer Science with a specialization in Computer Graphics and Geometry Processing. He is the head of the Institute for Computer Graphics and Multimedia at RWTH Aachen University.

After receiving his diploma in 1992 and his Ph.D. in 1994 in Computer Science from the Karlsruhe Institute of Technology he worked at the University of Wisconsin in Madison, University of Erlangen-Nuremberg and the Max Planck Institute of Computer Science before he moved to RWTH Aachen University in 2001. His research interests include 3D reconstruction, efficient geometry processing and optimization, realistic realtime rendering and (mobile) multimedia applications. For his research he was awarded with a number of academic prices including the Heinz-Maier-Leibnitz Prize 2000, the Eurographics Outstanding Technical Contribution Award 2004, the Günther Enderle Award (in 1999 and 2012), an ERC Advanced Grant 2013 and the Gottfried Wilhelm Leibniz Prize 2014. He has been named a Fellow of the Eurographics Association (2008) and a Distinguished Professor of RWTH Aachen University (2013).

Abstract: The conversion of raw geometric data (that typically comes in the form of unstructured triangle meshes) to high quality quad meshes is an important and challenging task. The complexity of the task results from the fact that quad mesh topologies are subject to global consistency requirements which cannot be dealt with by local constructions. This is why recent quad meshing techniques formulate the mesh generation process as a global optimization problem. By adding hard and soft constraints to this optimization, many desired properties such as structural simplicity, principal direction alignment, as well as injectivity can be guaranteed by construction. An even more challenging problem is the computation of quad layouts, where a coarse segmentation of the input surface into essentially rectangular patches is sought which also satisfies global consistency and shape quality requirements. While being structurally related, both problems need to be addressed by fundamentally different approaches. In my talk I will present some of these approaches and demonstrate that they can generate high quality quad meshes and quad layouts with a high degree of automation but that they also allow the user to interactively control the results by setting boundary conditions accordingly.
