      Shi, Zeyun; Alliez, Pierre; Desbrun, Mathieu; Bao, Hujun; Huang, Jin (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      In this paper, we formulate an automatic approach to the detection of partial, local, and global symmetries and orbits in arbitrary 3D datasets. We improve upon existing voting-based symmetry detection techniques by ...
    • Disk Density Tuning of a Maximal Random Packing

      We introduce an algorithmic framework for tuning the spatial density of disks in a maximal random packing, without changing the sizing function or radii of disks. Starting from any maximal random packing such as a Maximal ...
    • Planar Minimization Diagrams via Subdivision with Applications to Anisotropic Voronoi Diagrams 

      Bennett, Huck; Papadopoulou, Evanthia; Yap, Chee (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Let X = {f1, . . ., fn} be a set of scalar functions of the form fi : R2 →R which satisfy some natural properties. We describe a subdivision algorithm for computing a clustered e-isotopic approximation of the minimization ...
    • Deep Learning for Robust Normal Estimation in Unstructured Point Clouds 

      Boulch, Alexandre; Marlet, Renaud (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Normal estimation in point clouds is a crucial first step for numerous algorithms, from surface reconstruction and scene understanding to rendering. A recurrent issue when estimating normals is to make appropriate decisions ...
    • Interactive Modeling of Mechanical Objects 

      Ureta, Francisca Gil; Tymms, Chelsea; Zorin, Denis (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Objects with various types of mechanical joints are among the most commonly built. Joints implement a vocabulary of simple constrained motions (kinematic pairs) that can be used to build more complex behaviors. Defining ...
    • Stenciling: Designing Structurally-Sound Surfaces with Decorative Patterns 

      Schumacher, Christian; Thomaszewski, Bernhard; Gross, Markus (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present a novel method to design shells with artistic cutouts in a manner that produces a stable final result. The process of stenciling, removing material with a fixed shape, is a particularly appealing way to introduce ...
    • Mesh Statistics for Robust Curvature Estimation 

      Váša, Libor; Vaněček, Petr; Prantl, Martin; Skorkovská, Věra; Martínek, Petr; Kolingerová, Ivana (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      While it is usually not difficult to compute principal curvatures of a smooth surface of sufficient differentiability, it is a rather difficult task when only a polygonal approximation of the surface is available, because ...
    • Polycube Simplification for Coarse Layouts of Surfaces and Volumes 

      Cherchi, Gianmarco; Livesu, Marco; Scateni, Riccardo (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Representing digital objects with structured meshes that embed a coarse block decomposition is a relevant problem in applications like computer animation, physically-based simulation and Computer Aided Design (CAD). One ...
    • Scale-Invariant Directional Alignment of Surface Parametrizations 

      Campen, Marcel; Ibing, Moritz; Ebke, Hans-Christian; Zorin, Denis; Kobbelt, Leif (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Various applications of global surface parametrization benefit from the alignment of parametrization isolines with principal curvature directions. This is particularly true for recent parametrization-based meshing approaches, ...
    • Incorporating Sharp Features in the General Solid Sweep Framework 

      Adsul, Bharat; Machchhar, Jinesh; Sohoni, Milind (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      This paper extends a recently proposed robust computational framework for constructing the boundary representation (brep) of the volume swept by a given smooth solid moving along a one parameter family h of rigid motions. ...
    • SGP 2016: Frontmatter 

      Maks Ovsjanikov; Daniele Panozzo (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    • Iterative Closest Conformal Maps between Planar Domains 

      Segall, Aviv; Ben-Chen, Mirela (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Conformal maps between planar domains are an important tool in geometry processing, used for shape deformation and image warping. The Riemann mapping theorem guarantees that there exists a conformal map between any two ...
    • Advection-Based Function Matching on Surfaces 

      Azencot, Omri; Vantzos, Orestis; Ben-Chen, Mirela (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      A tangent vector field on a surface is the generator of a smooth family of maps from the surface to itself, known as the flow. Given a scalar function on the surface, it can be transported, or advected, by composing it ...
    • Near-Isometric Level Set Tracking 

      Tao, Michael; Solomon, Justin; Butscher, Adrian (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Implicit representations of geometry have found applications in shape modeling, simulation, and other graphics pipelines. These representations, however, do not provide information about the paths of individual points as ...
    • Exploration of Empty Space among Spherical Obstacles via Additively Weighted Voronoi Diagram 

      Manak, Martin (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Properties of granular materials or molecular structures are often studied on a simple geometric model - a set of 3D balls. If the balls simultaneously change in size by a constant speed, topological properties of the empty ...
