Our research project "GoodShape" is supported by the European Research Council ("Starting Grant Project"). This is a long-term project (5 years) aiming at developping next-generation geometry processing. Links: The European Research Council. Short article on Inria website. Article in ERCIM news Executive summary: Project GOODSHAPE (Numerical Geometric Abstraction: from bits to equations), involves several fundamental aspects of 3D modelling and computer graphics. GOODSHAPE is taking a new approach to the classic, essential problem of sampling, or the digital representation of objects in a computer. This new approach proposes to simultaneously consider the problem of approximating the solution of a partial differential equation and the optimal sampling problem. The proposed approach, based on the theory of numerical optimization, is likely to lead to new algorithms, more efficient than existing methods. Possible applications are envisioned in inverse engineering and oil exploration.
Le projet en quelques mots: Le projet GOODSHAPE (Abstraction Geometrique Numérique: des bits aux équations) concerne certains aspects fondamentaux de la modélisation 3D et du graphisme par ordinateur. GOODSHAPE reconsidère d'une nouvelle manière le problème fondamental de l'échantillonage, à savoir la manière de représenter des objets dans un ordinateur. Cette nouvelle approche propose de considérer en meme temps le problème de l'approximation de la solution d'une équations aux dérivées partielle et celui de l'échantillonage optimal. L'approche proposée, fondée sur la théorie de l'optimisation numérique, a des chances d'aboutir à de nouveaux algorithmes, bien plus efficaces que les méthodes existantes. Des applications possibles sont envisagées dans le domaine de l'ingénierie inverse et de l'exploration pétrolière. |
