BSP-fields: An Exact Representation of Polygonal Objects by Differentiable Scalar Fields Based on Binary Space Partitioning [PDF]
, 2011 The problem considered in this work is to find a dimension independent algorithm for the generation of signed scalar fields exactly representing polygonal objects and satisfying the following requirements: the defining real function takes zero value ...

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

Compressing the property mapping of polygon meshes [PDF]
Proceedings Ninth Pacific Conference on Computer Graphics and Applications. Pacific Graphics 2001, 2002 Many polygon meshes have properties such as shading normals, colours, texture coordinates, and/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.

A Velocity-based Moving Mesh Virtual Element Method [PDF]
, 2022 We present a velocity-based moving mesh virtual element method for the numerical solution of PDEs involving moving boundaries. The virtual element method is used for computing both the mesh velocity and a conservative Arbitrary Lagrangian-Eulerian solution transfer on general polygonal meshes.

Evaluation of geometric deviations in rapid prototyped three-dimensional models created from computed tomography data [PDF]
Digital Diagnostics, 2021 BACKGROUND: Computer-aided design and three-dimensional printing have been used in various clinical and fundamental medicine fields, especially in surgery. For example, in the preoperative period, the correspondence of printed products to the anatomy can

POLYLLA: Polygonal meshing algorithm based on terminal-edge regions [PDF]
arXiv, 2022 This paper presents an algorithm to generate a new kind of polygonal mesh obtained from triangulations. Each polygon is built from a terminal-edge region surrounded by edges that are not the longest-edge of any of the two triangles that share them. The algorithm is termed Polylla and is divided into three phases.

Morphing of Triangular Meshes in Shape Space [PDF]
, 2008 We present a novel approach to morph between two isometric poses of the same non-rigid object given as triangular meshes. We model the morphs as linear interpolations in a suitable shape space $\mathcal{S}$.
