Approximating uniform triangular meshes in polygons
Theoretical Computer Science, 2000 AbstractWe consider the problem of triangulating a convex polygon using n Steiner points under the following optimality criteria: (1) minimizing the overall edge length ratio; (2) minimizing the maximum edge length; and (3) minimizing the maximum triangle perimeter. We establish a relation of these problems to a certain extreme packing problem.

Hessian Eigenfunctions for Triangular Mesh Parameterization [PDF]
Proceedings of the 11th Joint Conference on Computer Vision, Imaging and Computer Graphics Theory and Applications, 2016 Hessian Locally Linear Embedding (HLLE) is an algorithm that computes the nullspace of a Hessian functional H for Dimensionality Reduction (DR) of a sampled manifold M. This article presents a variation of classic HLLE for parameterization of 3D triangular meshes.

Constrained CVT meshes and a comparison of triangular mesh generators
Computational Geometry, 2009 AbstractMesh generation in regions in Euclidean space is a central task in computational science, and especially for commonly used numerical methods for the solution of partial differential equations, e.g., finite element and finite volume methods. We focus on the uniform Delaunay triangulation of planar regions and, in particular, on how one selects ...

Mesh smoothing algorithm based on exterior angles split.
PLoS ONE, 2020 Since meshes of poor quality give rise to low accuracy in finite element analysis and kinds of inconveniences in many other applications, mesh smoothing is widely used as an essential technique for the improvement of mesh quality.

Parameterization for fitting triangular mesh [PDF]
Progress in Natural Science, 2006 Abstract In recent years, with the development of 3D data acquisition equipments, the study on reverse engineering has become more and more important. However, the existing methods for parameterization can hardly ensure that the parametric domain is rectangular, and the parametric curve grid is regular.

FESOM-C v.2: coastal dynamics on hybrid unstructured meshes [PDF]
Geoscientific Model Development, 2019 We describe FESOM-C, the coastal branch of the Finite-volumE Sea ice – Ocean Model (FESOM2), which shares with FESOM2 many numerical aspects, in particular its finite-volume cell-vertex discretization.
