• Nguyen Tuan Thien (JKU, LINZ) visited us from March to May, to collaborate with B. Mourrain and A. Galligo on parameterization problems in isogeometric analysis, for his secondement in the context of the ITN Marie-Curie SAGA.

Participation In International Programs

PAI STAR South Corea collaboration

Participants : Laurent Busé, André Galligo, Evelyne Hubert, Angelos Mantzaflaris, Bernard Mourrain.

The objective of this collaboration is to conduct research in algebraic techniques for solving geometric modeling problems. More specially, we are interested in developing efficient and robust methods to solve non-linear constraints which appear in geometric computation. These methods will be used in applications such as shape design and reconstruction for solving interpolation or approximation problems. A typical area in which we will apply our methods is ship design. Experimentation and validation will lead to open source software implementation.

Collaborators from Seoul National University: Tae-Wan Kim, Sharma Rajiv, Hur Seok, Yeong-hwa Seo.

Tae-Wan Kimm visited INRIA-GALAAD from April 17 to April 23.
