Quadrilateral mesh simplification [PDF]
ACM Transactions on Graphics, 2008 We introduce a simplification algorithm for meshes composed of quadrilateral elements. It is reminiscent of edge-collapse based methods for triangle meshes, but takes a novel approach to the challenging problem of maintaining the quadrilateral connectivity during level-of-detail creation.

Mesh Simplification With Appearance-Driven Optimizations
IEEE Access, 2020 In this work, we propose a novel solution for simplifying texture-mapped three-dimensional (3D) meshes. It simplifies a 3D triangular mesh to optimally preserve the visual appearance of the original texture-mapped model at reduced vertex budgets.

Streaming Simplification of Tetrahedral Meshes [PDF]
IEEE Transactions on Visualization and Computer Graphics, 2007 Unstructured tetrahedral meshes are commonly used in scientific computing to represent scalar, vector, and tensor fields in three dimensions. Visualization of these meshes can be difficult to perform interactively due to their size and complexity. By reducing the size of the data, we can accomplish real-time visualization necessary for scientific ...

Building Geometry Simplification for Improving Mesh Quality of Numerical Analysis Model
Applied Sciences, 2020 Numerical analysis, especially the finite volume method (FVM), is one of the primary approaches employed when evaluating a building environment. A complicated geometry can degrade the mesh quality, leading to numerical diffusions and errors.

Restricted Mesh Simplification Using Edge Contractions [PDF]
International Journal of Computational Geometry & Applications, 2006 We consider the problem of simplifying a planar triangle mesh using edge contractions, under the restriction that the resulting vertices must be a subset of the input set. That is, contraction of an edge must be made onto one of its adjacent vertices, which results in removing the other adjacent vertex.
