Regular meshes from polygonal patterns
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
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
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.

Tsallis Entropy for Geometry Simplification
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 ...

THE USE OF BREAKLINES OF HYDROGRAPHIC OBJECTS IN THREE-DIMENSIONAL MODELING OF CITIES [PDF]
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.

Structure-aware Building Mesh Polygonization
We introduce a novel approach for the polygonization of Multi-view Stereo (MVS) meshes of buildings, which results in compact and topologically valid models. The main characteristic of our method is structure awareness, i.e., the recovery and preservation of the initial mesh primitives and their adjacencies.

Mesh smoothing algorithm based on exterior angles split.
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.

A steganalytic algorithm for 3D polygonal meshes [PDF]
We propose a steganalytic algorithm for watermarks embedded by Cho et al.'s mean-based algorithm [1]. The main observation is that while in a clean model the means of Cho et al.'s normalized histogram bins are expected to follow a Gaussian distribution, in a marked model their distribution will be bimodal. The proposed algorithm estimates the number of
