  • Schrödinger Operator for Sparse Approximation of 3D Meshes 

    Choukroun, Yoni; Pai, Gautam; Kimmel, Ron (The Eurographics Association, 2017)
    We introduce a Schrödinger operator for spectral approximation of meshes representing surfaces in 3D. The operator is obtained by modifying the Laplacian with a potential function which defines the rate of oscillation of ...
  • PCR: A Geometric Cocktail for Triangulating Point Clouds Beautifully Without Angle Bounds 

    Leitão, Gonçalo N. V.; Gomes, Abel J. P. (The Eurographics Association, 2017)
    Reconstructing a triangulated surface from a point cloud through a mesh growing algorithm is a difficult problem, in largely because they use bounds for the admissible dihedral angle to decide on the next triangle to be ...
  • Localized Manifold Harmonics for Spectral Shape Analysis 

    Melzi, Simone; Rodolà, Emanuele; Castellani, Umberto; Bronstein, Michael M. (The Eurographics Association, 2017)
    The use of Laplacian eigenfunctions is ubiquitous in a wide range of computer graphics and geometry processing applications. In particular, Laplacian eigenbases allow generalizing the classical Fourier analysis to manifolds. ...
  • A Primal-to-Primal Discretization of Exterior Calculus on Polygonal Meshes 

    Ptackova, Lenka; Velho, Luiz (The Eurographics Association, 2017)
    Discrete exterior calculus (DEC) offers a coordinate-free discretization of exterior calculus especially suited for computations on curved spaces. We present an extended version of DEC on surface meshes formed by general ...

    Guerrero, Paul; Winnemöller, Holger; Li, Wilmot; Mitra, Niloy J. (The Eurographics Association, 2017)
    In the context of scene understanding, a variety of methods exists to estimate different information channels from mono or stereo images, including disparity, depth, and normals. Although several advances have been reported ...
  • Sequentially-Defined Compressed Modes via ADMM 

    Houston, Kevin (The Eurographics Association, 2017)
    The eigenfunctions of the discrete Laplace-Beltrami operator have played an important role in many aspects of geometry processing. Given the success of sparse representation methods in areas such as compressive sensing it ...
  • Symposium on Geometry Processing 2017: Frontmatter 

    Bærentzen, Jakob Andreas; Hildebrandt, Klaus (Eurographics Association, 2017)
  • 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 ...
  • 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 ...
  • Disk Density Tuning of a Maximal Random Packing 

    Ebeida, Mohamed S.; Rushdi, Ahmad A.; Awad, Muhammad A.; Mahmoud, Ahmed H.; Yan, Dong-Ming; English, Shawn A.; Owens, John D.; Bajaj, Chandrajit L.; Mitchell, Scott A. (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    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 ...
  • 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 ...
  • 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 ...
  • Symmetry and Orbit Detection via Lie-Algebra Voting 

    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 ...
  • Identifying Style of 3D Shapes using Deep Metric Learning 

    Lim, Isaak; Gehre, Anne; Kobbelt, Leif (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    We present a method that expands on previous work in learning human perceived style similarity across objects with different structures and functionalities. Unlike previous approaches that tackle this problem with the help ...
  • Learning 3D Scene Synthesis from Annotated RGB-D Images 

    Kermani, Zeinab Sadeghipour; Liao, Zicheng; Tan, Ping; Zhang, Hao (Richard) (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    We present a data-driven method for synthesizing 3D indoor scenes by inserting objects progressively into an initial, possibly, empty scene. Instead of relying on few hundreds of hand-crafted 3D scenes, we take advantage ...
  • Construction of Topologically Correct and Manifold Isosurfaces 

    Grosso, Roberto (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    We present a simple method to describe the geometry and topologically classify the intersection of level sets of trilinear interpolants with a reference unit cell. The solutions of three quadratic equations are used to ...

    Parakkat, Amal Dev; Muthuganapathy, Ramanathan (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    Given a planar point set sampled from an object boundary, the process of approximating the original shape is called curve reconstruction. In this paper, a novel non-parametric curve reconstruction algorithm based on Delaunay ...
  • Curve Reconstruction with Many Fewer Samples 

    Ohrhallinger, Stefan; Mitchell, Scott A.; Wimmer, Michael (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    We consider the problem of sampling points from a collection of smooth curves in the plane, such that the CRUST family of proximity-based reconstruction algorithms can rebuild the curves. Reconstruction requires a dense ...

    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 ...
