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

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.

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

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

Compressing the property mapping of polygon meshes [PDF]
Proceedings Ninth Pacific Conference on Computer Graphics and Applications. Pacific Graphics 2001, 2002 Summary: Many polygon meshes have properties such as shading normals, colors, texture coordinates, or material attributes that are associated with the vertices, faces, or corners of the mesh. While current research in mesh compression has focused on connectivity and geometry coding, the compression of properties has received less attention.

A TWELVE NODED FINITE ELEMENT APPROXIMATION TO 2D-POISSON EQUATIONS WITH A DIRAC LINE SOURCE [PDF]
Journal of Mechanics of Continua and Mathematical SciencesThis paper presents the finite element approach to solving the Poisson equation. Using Dirichlet boundary conditions in a two-dimensional polygonal region, the polygon to be discretized is made up of twelve-noded quadrilateral structured meshes.
