We propose a new compression method devoted to large structuredhexahedral meshes having discontinuities. It is dedicated to applicationssuch as visualization or physical simulations whose managementby any workstation or mobile device with limited memoryand bandwidth is critical. Our method relies on a multiresolutionanalysis that generates a...

Nous présentons une technique originale de décomposition progressive en résolution pour maillages hexaédriques structurés. Cette technique prend en compte les discontinuités géométriques potentiellement présentes dans les données issues des géosciences (failles, etc.), afin de préserver leur morphologie au travers des résolutions. Des...

With huge data acquisition progresses realized in the past decades and acquisition systems now able to produce high resolution point clouds, the digitization of physical terrains becomes increasingly more precise. Such extreme quantities of generated and modeled data greatly impact computational performances on many levels: storage media,...
