Harmonic numbers, Catalan's triangle and mesh patterns [PDF]
Discrete Mathematics, 2012 The notion of a mesh pattern was introduced recently, but it has already proved to be a useful tool for description purposes related to sets of permutations. In this paper we study eight mesh patterns of small lengths. In particular, we link avoidance of one of the patterns to the harmonic numbers, while for three other patterns we show their ...

Streaming compression of triangle meshes [PDF]
ACM SIGGRAPH 2005 Sketches on - SIGGRAPH '05, 2005 Current mesh compression schemes encode triangles and vertices in an order derived from systematically traversing the connectivity graph. These schemes struggle with gigabyte-sized mesh input where the construction and the usage of the data structures that support topological traversal queries become I/O-inefficient and require large amounts of ...

ON THE ASSOCIATION OF LIDAR POINT CLOUDS AND TEXTURED MESHES FOR MULTI-MODAL SEMANTIC SEGMENTATION [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 The semantic segmentation of the huge amount of acquired 3D data has become an important task in recent years. We propose a novel association mechanism that enables information transfer between two 3D representations: point clouds and meshes.

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

Toward the Assessment of Intrinsic Geometry of Implicit Brain MRI Manifolds
IEEE Access, 2021 Principal and Gaussian curvatures are commonly used intrinsic metrics for geometric morphometrics analysis: to assess morphometric changes in brain geometry (developmental neuroimaging studies), to quantify shape deformation (organ motion assessment), or

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 ...

Size-Adaptive Texture Atlas Generation and Remapping for 3D Urban Building Models
ISPRS International Journal of Geo-Information, 2021 A high-fidelity 3D urban building model requires large quantities of detailed textures, which can be non-tiled or tiled ones. The fast loading and rendering of these models remain challenges in web-based large-scale 3D city visualization. The traditional

A Topological Framework for Interactive Queries on 3D Models in the Web
The Scientific World Journal, 2014 Several technologies exist to create 3D content for the web. With X3D, WebGL, and X3DOM, it is possible to visualize and interact with 3D models in a web browser.
