Michael Kaufmann - University of Tübingen, GermanyOn Orthogonal Drawings of plane and not so plane graphs
The orthogonal drawing model is one of the basic models in graph drawing. Algorithms and variants have developed from the very beginning of the field, over the years and it is still very present in recent works.
In my talk, I will make a personal walk through the last 30 years of orthogonal graph drawing. I will highlight some topics that I like and which you possibly don't know, still containing remarkable techniques. At the end, I will give some open questions and directions from the past that might be remarkable.
Monique Teillaud - INRIA Nancy - Grand Est, LORIA, FranceThe CGAL Project - cgal.org
CGAL, The Computational Geometry Algorithms Library, provides easy access to efficient and reliable geometric algorithms in the form of a C++ library. It is is used both in academia and industry, in various areas needing geometric computation, such as geographic information systems, computer aided design, molecular biology, medical imaging, computer graphics, and robotics.
The CGAL Project is a joint effort of several research groups in academia and their industrial partner GeometryFactory. It started in 1996 as a consortium of seven academic sites in Europe and Israel. In 2003, it has become an Open Source project, inviting developers from around the world to join.
This talk is definitely not going to be a CGAL course. Instead I will try to give insight about the history of the project and the multiple ingredients that have made it successful over the years: technical choices, development tools, project organization, license choice, etc, without forgetting the most important: the CGAL people.
