We study mesh refinement techniques for first-order hyperbolic equations. A refinement method for use with the leap-frog scheme is defined and its stability established. The remainder of the paper is devoted to a discussion of the effects of nonuniform grids and the circumstances under which they may be used.

A new method for smoothly connecting different patches on triangle meshes with arbitrary connectivity, called mesh blending, is presented. A major feature of mesh blending is to move vertices of the blending region to a virtual blending surface by choosing an appropriate parameterization of those vertices.

Summary: This paper describes the implementation of an `active-mesh' that is to be automatically created and configured directly from a single frame of an image sequence. The aim of this approach is to use the derived mesh to perform visual tracking in unconstrained motion environments, allowing movement of the camera, the scene and even the inclusion ...

This work introduces “generalized meshes”, a type of meshes suited for the discretization of partial differential equations in non-regular geometries. Generalized meshes extend regular simplicial meshes by allowing for overlapping elements and more flexible adjacency relations.

Skin graft meshing, over-meshing and cross-meshing
Split skin grafts (SSGs) are often meshed to increase their size and allow exudate to escape. We investigated the expansion obtained with meshing, and the possibility of re-meshing skin that has already been meshed ("overmeshing"). Both useful and inadvisable permutations are illustrated.Thin porcine SSGs were sideways meshed, or meshed with ratios of ...

Mesh Draping: Parametrization‐Free Neural Mesh Transfer
AbstractDespite recent advances in geometric modelling, 3D mesh modelling still involves a considerable amount of manual labour by experts. In this paper, we introduce Mesh Draping: a neural method for transferring existing mesh structure from one shape to another. The method drapes the source mesh over the target geometry and at the same time seeks to

Distributions of several infinite families of mesh patterns [PDF]
Br\"and\'en and Claesson introduced mesh patterns to provide explicit expansions for certain permutation statistics as linear combinations of (classical) permutation patterns.

A fast and robust patient specific Finite Element mesh registration technique: application to 60 clinical cases [PDF]
Finite Element mesh generation remains an important issue for patient specific biomechanical modeling. While some techniques make automatic mesh generation possible, in most cases, manual mesh generation is preferred for better control over the sub ...

Stability of explicit one-step methods for P1-finite element approximation of linear diffusion equations on anisotropic meshes [PDF]
We study the stability of explicit one-step integration schemes for the linear finite element approximation of linear parabolic equations. The derived bound on the largest permissible time step is tight for any mesh and any diffusion matrix within a ...
