The paper deals with the problem of analyzing and visualizinglarge-size volume data sets.To this aim, we consider multiresolution representations based on a decomposition of the field domain into tetrahedral cells.We compare two types of multiresolution representations that differ on the rule applied to refine an initial coarse mesh: one is based on tetrahedron bisection, and one based on vertex split.The two representations can be viewedas instances of a common multiresolution model, that we call amultiresolution mesh.Encoding data structures for the two representations are briefly described. An experimental comparison on structured volume data sets is presented.
