Algorithmes parallèles de manipulation de maillages

Abstract : This thesis deals with different aspects of mesh processing, and the way those operations can be done in parallel, or using distributed memory, when GPUs and supercomputers are more and more commonly used. We present surfacic and volumetric mesh smoothing algorithms, based upon image processing techniques (bilateral filter, local histograms). After those geometric considerations, we talk about topologic methods, as local remeshing, enabling one to generate, from a tetrahedral mesh, one layer of good quality prisms and hexahedron, allowing fluid mechanics simulations in those near-surface areas. Finally, we present a meshing technique based upon particular interactions, in order to construct quad-dominant meshes.
