(H)exaschrink: Multiresolution Compression of Large Structured Hexahedral Meshes with Discontinuities in Geosciences

Abstract : We propose a new compression method devoted to large structured hexahedral meshes having discontinuities. It is dedicated to applications such as visualization or physical simulations whose management by any workstation or mobile device with limited memory and bandwidth is critical. Our method relies on a multiresolution analysis that generates a hierarchy of meshes at increasing resolutions. Our technique also uses a discontinuity tracking feature for their preservation, whatever the resolutions, and consequently maintains a coherent geometry with respect to the original mesh. Experimental results emphasize the quality of our compression, in terms of both geometrical distortion and compression ratio.
