Polygonal finite element-based content-aware image warping
Computational Visual Media, 2023 Mesh-based image warping techniques typically represent image deformation using linear functions on triangular meshes or bilinear functions on rectangular meshes. This enables simple and efficient implementation, but in turn, restricts the representation

Preparation Of Control Space For Remeshing Of Polygonal Surfaces
Computer Science, 2013 The subject of the article concerns the issues of remeshing, transforming a polygonal mesh into a triangular mesh adapted to surface. From the initial polygonal mesh the curvature of surface and boundary is retrieved and used to calculate a metric tensor

Automatic Reconstruction of Building Façade Model from Photogrammetric Mesh Model
Remote Sensing, 2021 Three-dimensional (3D) building façade model reconstruction is of great significance in urban applications and real-world visualization. This paper presents a newly developed method for automatically generating a 3D regular building façade model from the

Discrete Laplacians on general polygonal meshes [PDF]
ACM Transactions on Graphics, 2011 While the theory and applications of discrete Laplacians on triangulated surfaces are well developed, far less is known about the general polygonal case. We present here a principled approach for constructing geometric discrete Laplacians on surfaces with arbitrary polygonal faces ...

A PLATFORM FOR MULTILAYERED DOCUMENTATION OF CULTURAL HERITAGE [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2021 This paper presents a platform for multilayered documentation of cultural heritage, inspired by the current lack of a heritage BIM approach capable of creating models with both high geometric accuracy and high semantic richness. The platform is developed

Boolean operations between two colliding shells: a robust, exact, and simple method
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2017 Boolean operations are classic procedures in computer-aided design, and allow the creation of complex objects by combining simple objects. Although Boolean operations are trivial in implicit surface representations, they are problematic in polygonal ...

Progressive compression of manifold polygon meshes [PDF]
Computers & Graphics, 2012 This paper presents a new algorithm for the progressive compression of manifold polygon meshes. The input surface is decimated by several traversals that generate successive levels of detail through a specific patch decimation operator which combines vertex removal and local remeshing.

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
