An Efficient Visualization Method for Polygonal Data with Dynamic Simplification
ISPRS International Journal of Geo-Information, 2018 Polygonal data often require rendering with symbolization and simplification in geovisualization. A common issue in existing methods is that simplification, symbolization and rendering are addressed separately, causing computational and data redundancies

A computational method for sharp interface advection [PDF]
Royal Society Open Science, 2016 We devise a numerical method for passive advection of a surface, such as the interface between two incompressible fluids, across a computational mesh.

Virtual Element Methods on Meshes with Small Edges or Faces
, 2017 We consider a model Poisson problem in $\R^d$ ($d=2,3$) and establish error estimates for virtual element methods on polygonal or polyhedral meshes that can contain small edges ($d=2$) or small faces ($d=3$).Comment: 36 ...

IET Networks, EarlyView., 2022 Abstract 3D scanning is rapidly becoming a key maintenance tool. Aerospace was a pioneer in adopting 3D scanning technology because aircraft manufacture and maintenance require precision. Monitoring deterioration, removing components for maintenance, and verifying covert operations are not practical or helpful without technology.

Deep Neural Network for 3D Shape Classification Based on Mesh Feature
Sensors, 2022 Virtual reality, driverless cars, and robotics all make extensive use of 3D shape classification. One of the most popular ways to represent 3D data is with polygonal meshes. In particular, triangular mesh is frequently employed.

A Nystr\"om-based finite element method on polygonal elements
, 2017 We consider families of finite elements on polygonal meshes, that are defined implicitly on each mesh cell as solutions of local Poisson problems with polynomial data.

Bijective Mappings Of Meshes With Boundary And The Degree In Mesh Processing [PDF]
, 2014 This paper introduces three sets of sufficient conditions, for generating bijective simplicial mappings of manifold meshes. A necessary condition for a simplicial mapping of a mesh to be injective is that it either maintains the orientation of all ...

Embedded Implicit Stand-ins for Animated Meshes: a Case of Hybrid Modelling [PDF]
, 2008 In this paper we address shape modelling problems, encountered in computer animation and computer games development that are difficult to solve just using polygonal meshes.
