Mesh quality metrics for isogeometric Bernstein–Bézier discretizations

open access: yesComputer Methods in Applied Mechanics and Engineering, 2020
High-order finite element methods harbor the potential to deliver improved accuracy per degree of freedom versus low-order methods. Their success, however, hinges upon the use of a curvilinear mesh of not only sufficiently high accuracy but also sufficiently high quality.

Geometric parameters in the target matrix mesh optimization paradigm

open access: yesPartial Differential Equations in Applied Mathematics, 2022
The Target Matrix Optimization Paradigm for improving mesh quality has always had, as its agenda, to create a direct path between application mesh quality requirements and a set of target matrices that can result in an optimal mesh that meets the ...

Textured Mesh Quality Assessment: Large-scale Dataset and Deep Learning-based Quality Metric

open access: yesACM Transactions on Graphics, 2023
Over the past decade, three-dimensional (3D) graphics have become highly detailed to mimic the real world, exploding their size and complexity. Certain applications and device constraints necessitate their simplification and/or lossy compression, which can degrade their visual quality.

Generic attribute deviation metric for assessing mesh simplification algorithm quality [PDF]

open access: yesProceedings. International Conference on Image Processing, 2003
This paper describes an efficient method to compare two triangular meshes. Meshes considered here contain geometric features as well as other surface attributes such as material colors, texture, temperature, radiation, etc. Two deviation measurements are presented to assess the differences between two meshes.
