Polycube-maps are used as base-complexes in various fields of computational geometry, including the generation of regular all-hexahedral meshes free of internal singularities. However, the strict alignment constraints behind polycube-based methods ma

Construction of optimal deformations is one of the long standing problems of computational mathematics. We consider the problem of computing quasi-isometric deformations with minimal possible quasi-isometry constant (global estimate for relative leng

Mapping a triangulated surface to 2D space (or a tetrahedral mesh to 3D space) is the most fundamental problem in geometry processing.In computational physics, untangling plays an important role in mesh generation: it takes a mesh as an input, and mo

Optimal mapping is one of the longest standing problems in computational mathematics.It is natural to measure relative length error to assess map quality.Maximum of such error is called quasi-isometry constant, and its minimization is a nontrivial ma

This thesis studies polycube methods for the generation of hexahedral meshes. These meshes, and more generally block structured meshes, are very much in demand for numerical simulations of physical phenomena (nuclear fission, flow, aerospace...). How

International audience; Given a triangulated surface, a unit length tangent vector field can be used to orient entities located on the surface, such as glyphs or strokes. When these entities are invariant under a π/2 rotation (squares, or curvature

Mesh untangling is still a hot topic in applied mathematics. Tangled or folded meshes appear in many applications involving mappings or deformations. Despite the fact that a large number of mesh untangling strategies was proposed during the last deca
