A great challenge for flow simulators of new generation is to gain more accuracy at well proximity within complex geological structures. For this purpose, a new approach based on...
The aim of this paper is to study the feasibility of using (irreversible) entropy production as driving force for a moving mesh. Such a method should be able to capture or track p...
In this paper, we propose a robust isotropic tetrahedral mesh generation method. An advancing front method is employed to control local mesh density and to easily preserve the ori...
Algorithms that detect silhouettes, creases, and other edge based features often perform per-edge and per-face mesh computations using global adjacency information. These are unsu...
Recently, various three-dimensional(3-D) mesh coding schemes have been proposed to improve compression efficiency or error resilience. However, we need to consider both coding effi...
The first stage in an adaptive finite element scheme (cf. [CAS95, bor1]) consists in creating an initial mesh of a given domain Ω, which is used to perform an initial computati...
Abstract. This article presents special quadrilateral quadratic refinement elements, which provide geometry and field continuity across Tjunctions where two elements are connecte...
In this paper, we propose a new fragile watermarking scheme for 3D meshes. Firstly, the watermark information is adaptively embedded into the mesh geometry by slightly adjusting t...
We present a meshing and rendering framework for tetrahedral meshes that constructs a multi-resolution representation and uses this representation to adapt the mesh to rendering p...
Generating triangular meshes from images is a task important to many applications. Usually, techniques that can do that either take as starting point a segmented image or generate...
