A Laplacian for Nonmanifold Triangle Meshes
Computer Graphics Forum, 2020 AbstractWe describe a discrete Laplacian suitable for any triangle mesh, including those that are nonmanifold or nonorientable (with or without boundary). Our Laplacian is a robust drop‐in replacement for the usual cotan matrix, and is guaranteed to have nonnegative edge weights on both interior and boundary edges, even for extremely poor‐quality ...

Progressive Compression of Triangle Meshes
Image Processing On Line, 2023 This paper details the first publicly available implementation of the progressive mesh compression algorithm described in the paper entitled "Compressed Progressive Meshes" [R. Pajarola and J. Rossignac, IEEE Transactions on Visualization and Computer Graphics, 6 (2000), pp. 79-93].

Well-Centered Triangulation [PDF]
, 2008 Meshes composed of well-centered simplices have nice orthogonal dual meshes (the dual Voronoi diagram). This is useful for certain numerical algorithms that prefer such primal-dual mesh pairs.

An Effective Method for Slicing Triangle Meshes Using a Freeform Curve
MathematicsSlicing 3D polygonal meshes is a fundamental operation in various applications such as virtual surgery, garment simulation, and game development. Existing methods primarily slice meshes using either a single line or a set of line segments approximating a

Segmenting reliefs on triangle meshes [PDF]
Proceedings of the 2006 ACM symposium on Solid and physical modeling, 2006 Sculptural reliefs are widely used in various industries for purposes such as applying brands to packaging and decorating porcelain. In order to easily apply reliefs to CAD models, it is often desirable to reverse-engineer previously designed and manufactured reliefs. 3D scanners can generate triangle meshes from objects with reliefs; however, previous

Multiresolution Computation of Conformal Structures of Surfaces [PDF]
Journal of Systemics, Cybernetics and Informatics, 2003 An efficient multiresolution method to compute global conformal structures of nonzero genus triangle meshes is introduced. The homology, cohomology groups of meshes are computed explicitly, then a basis of harmonic one forms and a basis of holomorphic ...

A tetrahedral space-filling curve for non-conforming adaptive meshes
, 2016 We introduce a space-filling curve for triangular and tetrahedral red-refinement that can be computed using bitwise interleaving operations similar to the well-known Z-order or Morton curve for cubical meshes.
