Activités de Recherche
Many works in simulation, modeling or geometry processing use multiple representations of the same object. They may correspond to different scales or to different levels of detail, especially in multiresolution applications. They may also correspond to models of different natures.
In simulation, most methods require volumetric meshing for the computation of deformation. To this first mesh a finer surface mesh is usually associated for realistic rendering. The use of multi-scale representation is also common in the field of image segmentation for mesh compression or simplification. At last, many algorithms make use of hierarchical structures to speed up the treatments, such as ray tracing and collision detection.
My research concerns the development of multi-scale combinatorial structures for geometric modeling, animation and geometry processing.
