....which also generate a new mesh starting from a given one. Such schemes primarily aim at adapting the complexity of the mesh to an acceptable level for graphics visualization hardware or simulation algorithms. For efficient mesh processing, most previous work have focused on semi regular remeshing [36, 34, 26, 33, 29], the lat ter techniques often requiring a first simplification stage. Kobbelt et al. focus on feature sensitive remeshing techniques [54, 10, 11] to reduce the artifacts produced when converting a given geometry into a triangle mesh. More recently, Gu et al. 24] proposed a technique for ....

....mesh faces according to a bucketing of face normals. Eck et al. 4] use a Voronoi based partition. These last two algorithms make little effort to adapt charts to surface geometry, so the chart boundaries can hinder simplification, leading to poor LaD approximations. MAPS [18] and Normal Meshes [8] map edges of the simplified base domain back to the original mesh. While the resulting charts adapt to surface geometry, their boundaries cut across faces of original mesh, requiring addition of new vertices and faces. For the applications in [8] 18] these additional vertices are only temporary, ....

....LaD approximations. MAPS [18] and Normal Meshes [8] map edges of the simplified base domain back to the original mesh. While the resulting charts adapt to surface geometry, their boundaries cut across faces of original mesh, requiring addition of new vertices and faces. For the applications in [8][18] these additional vertices are only temporary, because the mesh geometry is subsequently resampled. However, our application is to generate a PM from a userspecified mesh, whose connectivity is often carefully optimized, so the imposition of new vertices is a drawback. Chart ....

....improved force based approach to quickly converge to a refined mesh that adaptively fits the data with good aspect ratio triangles. 1. 2 Related Work Traditional Methods and Multiresolution proceed by first constructing an MC mesh and then improving it through simplification [20] and or remeshing [11, 29, 33, 28, 19]. Common mesh simplification algorithms have large memory footprints [21, 15] and are impractical for decimating meshes with millions of samples (see [35, 34] to address this issue) In addition, simplification algorithms create irregular connectivity meshes with non smooth parameterizations. ....

....filters more suitable for geometry. Careful examination of reconstructed geometry reveals some ringing artifacts with our current wavelets. Even for our semi regular meshes, there is still a fair amount of tangential information especially on the coarse levels. Recent work by Guskov et al. [15] shows that it is possible to construct normal meshes, i.e. meshes in which all wavelet coefficients lie exactly in the normal direction. The issues we discuss in this paper regarding geometry versus parameterization led to ideas such as coarsely quantizing the tangential components. These ....
