Construire un mailleur anisotrope de type Delaunay nécessite le développement d'un algorithme d'insertion de points en anisotrope dans une triangulation. Ce papier...

On rappelle ce qu'est la bascule la plus simple en trois dimensions, à savoir la bascule face-arête qui est la transformation dite «2-3» qui modifie deux tétraèdres en...

Given a finite sampling $P\subset\mathbbR^d$ of an unknown surface $S$, surface reconstruction is concerned with the calculation of a model of $S$ from $P$. The model...

Though Delaunay and regular triangulations are very well known geometric data structures, the problem of the robust removal of a vertex in a three-dimensional...

In this thesis, we look for methods for reconstructing an approximation of a manifold known only through a high-dimensional point cloud. Especially, we are interested...
