Towards Globally Optimal Normal Orientations for Large Point Clouds
(© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
Various processing algorithms on point set surfaces rely on consistently oriented normals (e.g. Poisson surface reconstruction). While several approaches exist for the calculation of normal directions, in most cases, their ...
Accurate and Efficient Computation of Laplacian Spectral Distances and Kernels
(© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
This paper introduces the Laplacian spectral distances, as a function that resembles the usual distance map, but exhibits properties (e.g. smoothness, locality, invariance to shape transformations) that make them useful ...
Enhancing Urban Façades via LiDAR‐Based Sculpting
(© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
Buildings with symmetrical façades are ubiquitous in urban landscapes and detailed models of these buildings enhance the visual realism of digital urban scenes. However, a vast majority of the existing urban building models ...
On the Stability of Functional Maps and Shape Difference Operators
(© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)
In this paper, we provide stability guarantees for two frameworks that are based on the notion of functional maps—the framework of shape difference operators and the one of analyzing and visualizing the deformations between ...
State of the Art on Stylized Fabrication
(© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)
Digital fabrication devices are powerful tools for creating tangible reproductions of 3D digital models. Most available printing technologies aim at producing an accurate copy of a tridimensional shape. However, fabrication ...
Part‐Based Mesh Segmentation: A Survey
(© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)
This paper surveys mesh segmentation techniques and algorithms, with a focus on part‐based segmentation, that is, segmentation that divides a mesh (featuring a 3D object) into meaningful parts. Part‐based segmentation ...
Field‐Aligned Isotropic Surface Remeshing
(© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)
We present a novel isotropic surface remeshing algorithm that automatically aligns the mesh edges with an underlying directional field. The alignment is achieved by minimizing an energy function that combines both centroidal ...
A Survey of Geometric Analysis in Cultural Heritage
(Copyright © 2016 The Eurographics Association and John Wiley & Sons Ltd., 2016)
We present a review of recent techniques for performing geometric analysis in cultural heritage (CH) applications. The survey is aimed at researchers in the areas of computer graphics, computer vision and CH computing, as ...
Efficient Computation of Smoothed Exponential Maps
(© 2019 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2019)
Many applications in geometry processing require the computation of local parameterizations on a surface mesh at interactive rates. A popular approach is to compute local exponential maps, i.e. parameterizations that ...
Robust Structure‐Based Shape Correspondence
(© 2019 The Eurographics Association and John Wiley & Sons Ltd., 2019)
We present a robust method to find region‐level correspondences between shapes, which are invariant to changes in geometry and applicable across multiple shape representations. We generate simplified shape graphs by jointly ...
