Delaunay Refinement Mesh Generation
Delaunay refinement is a technique for generating unstructured meshes of triangles or tetrahedra suitable for use in the finite element method or other numerical methods for solving partial differential equations. Popularized by the engineering community in the mid-1980s, Delaunay refinement operates by maintaining a Delaunay triangulation or Delaunay tetrahedralization, which is refined by the...
متن کاملMesh Segmentation Refinement
This paper proposes a method for refining existing mesh segmentations, employing a novel extension of the active contour approach to meshes. Given a segmentation, produced either by an automatic segmentation method or interactively, our algorithm propagates the segment boundaries to more appropriate locations. In addition, unlike most segmentation algorithms, our method allows the boundaries to...
متن کاملMesh refinement with color attributes
Although many sophisticated solutions have been proposed to reduce the geometry complexity of a 3D mesh, few of these take into account color and texture fields, which are fundamental for a visual appearance of high quality. We propose here an innovative solution which combines the concept of hierarchy in refining a mesh with color attributes with mesh regularization. It operates subdividing re...
متن کاملGeneralized 2d Delaunay Mesh Refinement
Delaunay refinement is a popular mesh generation method which makes it possible to derive mathematical guarantees with respect to the quality of the elements. Traditional Delaunay refinement algorithms insert Steiner points in a small enumerable number (one or two) of specific positions inside circumscribed circles of poor quality triangles and on encroached segments. In this paper we prove tha...
متن کاملAdaptive Mesh Refinement for Multiscale
plied and theoretical physics is to fully understand and predict the behavior of systems far from thermodynamic equilibrium,1–4 including those systems driven by an external force or experiencing a sudden change in environment (such as pressure or temperature). They also include systems transitioning from one metastable or long-lived state to another. The need to accurately model and numericall...
