Connectivity Compression for Irregular Quadrilateral Meshes [PDF]
arXiv, 2000 Applications that require Internet access to remote 3D datasets are often limited by the storage costs of 3D models. Several compression methods are available to address these limits for objects represented by triangle meshes. Many CAD and VRML models, however, are represented as quadrilateral meshes or mixed triangle/quadrilateral meshes, and these ...

Tracing cross-free polylines oriented by a N-symmetry direction field on triangulated surfaces [PDF]
, 2013 We propose an algorithm for tracing polylines on a triangle mesh such that: they are aligned with a N-symmetry direction field, and two such polylines cannot cross or merge. This property is fundamental for mesh segmentation and is very difficult to enforce with numerical integration of vector fields. We propose an alternative solution based on "stream-

ℓ_1-Based Construction of Polycube Maps from Complex Shapes [PDF]
, 2014 Polycube maps of triangle meshes have proved useful in a wide range of applications, including texture mapping and hexahedral mesh generation. However, constructing either fully automatically or with limited user control a low-distortion polycube from a ...

An extended triangulation to the Marching Cubes 33 algorithm
Journal of the Brazilian Computer Society, 2019 The Marching Cubes algorithm is arguably the most popular isosurface extraction algorithm. Since its inception, two problems have lingered, namely, triangle quality and topology correctness.

Advanced Healthcare Materials, EarlyView.In this study, a novel cationic peptide, IW is designed and synthesized, with a tandem‐repeat sequence demonstrating potent activities against a broad spectrum of clinically relevant Carbapenem‐resistant Enterobacteriaceae in both the planktonic and biofilm states. IW is then formulated with P407 to form IW‐P407 colloids.

Study on boundary search method for DFM mesh generation [PDF]
China Foundry, 2012 The boundary mesh of the casting model was determined by direct calculation on the triangular facets extracted from the STL file of the 3D model. Then the inner and outer grids of the model were identified by the algorithm in which we named Inner Seed ...
