Simultaneous Smoothing and Untangling of 2D Meshes Based on Explicit Element Geometric Transformation and Element Stitching

open access: yesApplied Sciences, 2020
Mesh quality can affect both the accuracy and efficiency of numerical solutions. This paper first proposes a geometry-based smoothing and untangling method for 2D meshes based on explicit element geometric transformation and element stitching.

Compressing the property mapping of polygon meshes [PDF]

open access: yesProceedings Ninth Pacific Conference on Computer Graphics and Applications. Pacific Graphics 2001, 2002
Summary: Many polygon meshes have properties such as shading normals, colors, texture coordinates, or material attributes that are associated with the vertices, faces, or corners of the mesh. While current research in mesh compression has focused on connectivity and geometry coding, the compression of properties has received less attention.

Virtual Element Methods for hyperbolic problems on polygonal meshes [PDF]

open access: yes, 2016
In the present paper we develop the Virtual Element Method for hyperbolic problems on polygonal meshes, considering the linear wave equations as our model problem. After presenting the semi-discrete scheme, we derive the convergence estimates in H^1 semi-

Regular meshes from polygonal patterns

open access: yesACM Transactions on Graphics, 2017
We present a framework for designing shapes from diverse combinatorial patterns, where the vertex 1-rings and the faces are as rotationally symmetric as possible, and define such meshes as regular. Our algorithm computes the geometry that brings out the symmetries encoded in the combinatorics. We then allow designers and artists to envision and realize

Anisotropic mesh quality measures and adaptation for polygonal meshes [PDF]

open access: yesJournal of Computational Physics, 2020
Anisotropic mesh quality measures and anisotropic mesh adaptation are studied for polygonal meshes. Three sets of alignment and equidistribution measures are developed, one based on least squares fitting, one based on generalized barycentric mapping, and the other based on singular value decomposition of edge matrices.

Virtual Elements for the Navier-Stokes problem on polygonal meshes [PDF]

open access: yes, 2017
A family of Virtual Element Methods for the 2D Navier-Stokes equations is proposed and analysed. The schemes provide a discrete velocity field which is point-wise divergence-free.

Tsallis Entropy for Geometry Simplification

open access: yesEntropy, 2011
This paper presents a study and a comparison of the use of different information-theoretic measures for polygonal mesh simplification. Generalized measures from Information Theory such as Havrda–Charvát–Tsallis entropy and mutual information have been ...

Self-Replicating Strands that Self-Assemble into User-Specified Meshes [PDF]

open access: yes, 2005
It has been argued that a central objective of nanotechnology is to make products inexpensively, and that self-replication is an effective approach to very low-cost manufacturing.
