Volumetric Functional Maps
Filippo Maggioli, Simone Melzi, Marco Livesu
Computing volumetric correspondences between 3D shapes is a prominent tool for medical and industrial applications. In this work, we pave the way for spectral volume mapping, exten…
Hex-Mesh Generation and Processing: a Survey
Nico Pietroni, Marcel Campen, Alla Sheffer +7
In this article, we provide a detailed survey of techniques for hexahedral mesh generation. We cover the whole spectrum of alternative approaches to mesh generation, as well as pos…
Optimal Dual Schemes for Adaptive Grid Based Hexmeshing
Marco Livesu, Luca Pitzalis, Gianmarco Cherchi
Hexahedral meshes are an ubiquitous domain for the numerical resolution of partial differential equations. Computing a pure hexahedral mesh from an adaptively refined grid is a pro…
A Survey of Algorithms for Geodesic Paths and Distances
Keenan Crane, Marco Livesu, Enrico Puppo +1
Numerical computation of shortest paths or geodesics on curved domains, as well as the associated geodesic distance, arises in a broad range of applications across digital geometry…
Real-time Deformation with Coupled Cages and Skeletons
Fabrizio Corda, Jean-Marc Thiery, Marco Livesu +3
Skeleton-based and cage-based deformation techniques represent the two most popular approaches to control real-time deformations of digital shapes and are, to a vast extent, comple…
Benchmark of Polygon Quality Metrics for Polytopal Element Methods
M. Attene, S. Biasotti, S. Bertoluzza +6
Polytopal Element Methods (PEM) allow to solve differential equations on general polygonal and polyhedral grids, potentially offering great flexibility to mesh generation algorithm…
Surface2Volume: Surface Segmentation Conforming Assemblable Volumetric Partition
Chrystiano Araújo, Daniela Cabiddu, Marco Attene +3
Users frequently seek to fabricate objects whose outer surfaces consist of regions with different surface attributes, such as color or material. Manufacturing such objects in a sin…
Loopy Cuts: Surface-Field Aware Block Decomposition for Hex-Meshing
Marco Livesu, Nico Pietroni, Enrico Puppo +2
We present a new fully automatic block-decomposition hexahedral meshing algorithm capable of producing high quality meshes that strictly preserve feature curve networks on the inpu…
HexaLab.net: an online viewer for hexahedral meshes
Matteo Bracci, Marco Tarini, Nico Pietroni +2
We introduce HexaLab: a WebGL application for real time visualization, exploration and assessment of hexahedral meshes. HexaLab can be used by simply opening www.hexalab.net. Our v…
From 3D Models to 3D Prints: an Overview of the Processing Pipeline
Marco Livesu, Stefano Ellero, Jonás Martìnez +2
Due to the wide diffusion of 3D printing technologies, geometric algorithms for Additive Manufacturing are being invented at an impressive speed. Each single step, in particular al…
