Molecular Surface Remeshing with Local Region Refinement

Isotropic Surface Remeshing

This paper proposes a new method for isotropic remeshing of triangulated surface meshes. Given a triangulated surface mesh to be resampled and a user-specified density function defined over it, we first distribute the desired number of samples by generalizing error diffusion, commonly used in image halftoning, to work directly on mesh triangles and feature edges. We then use the resulting sampl...

Surface Remeshing and Applications

Due to the focus of popular graphic accelerators, triangle meshes remain the primary representation for 3D surfaces. They are the simplest form of interpolation between surface samples, which may have been acquired with a laser scanner, computed from a 3D scalar field resolved on a regular grid, or identified on slices of medical data. Typical methods for the generation of triangle meshes from ...

About Surface Remeshing

In this paper we present a general scheme suitable to optimize an arbitrary given surface triangulation representing a piecewise linear approximation of an underlying surface geometry The proposed approach is based on two steps related to i the extraction of a geometric mesh based on a simpli cation procedure ii the optimization of this mesh with respect to the model geometry as well as to the ...

Geodesic-based Surface Remeshing

Generation of surface meshes remains an active research problem despite the many publications addressing this topic. The main issues which must be treated by a good remeshing algorithm are: element quality, sizing control, approximation accuracy, robustness and efficiency. One reason surface meshing is such a challenging problem is the fact that using the Euclidean metric to measure distances b...
