Compressing the property mapping of polygon meshes [PDF]
Proceedings 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.

Regular meshes from polygonal patterns
ACM 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

Breaking Permutation-Based Mesh Steganography and Security Improvement
IEEE Access, 2019 Permutation-based steganography in polygonal meshes can provide considerably large embedding capacities for hiding secret messages. However, corresponding steganalysis techniques against such methods have never been studied.

Survey of polygonal surface simplification algorithms on GPU
Труды Института системного программирования РАН, 2018 Rendering time depends on number of faces in polygonal mesh. Displaying large number of objects or objects with a lot of faces can result in performance degradation.

THE USE OF BREAKLINES OF HYDROGRAPHIC OBJECTS IN THREE-DIMENSIONAL MODELING OF CITIES [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2023 Three-dimensional polygonal models are used for various tasks. They are created based on aerial photography or aerial laser scanning. In this paper, a study is conducted on what tasks require the correct geometry of the model on water bodies.

Tsallis Entropy for Geometry Simplification
Entropy, 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 ...

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.
