Recent Submissions

  • Limit Shapes - A Tool for Understanding Shape Differences and Variability in 3D Model Collections 

    Huang, Ruqi; Achlioptas, Panos; Guibas, Leonidas; Ovsjanikov, Maks (The Eurographics Association and John Wiley & Sons Ltd., 2019)
    We propose a novel construction for extracting a central or limit shape in a shape collection, connected via a functional map network. Our approach is based on enriching the latent space induced by a functional map network ...
  • On Evaluating Consensus in RANSAC Surface Registration 

    Hruda, Lukáš; Dvořák, Jan; Váša, Libor (The Eurographics Association and John Wiley & Sons Ltd., 2019)
    Random Sample Consensus is a powerful paradigm that was successfully applied in various contexts, including Location Determination Problem, fundamental matrix estimation and global 3D surface registration, where many ...
  • Parallel Globally Consistent Normal Orientation of Raw Unorganized Point Clouds 

    Jakob, Johannes; Buchenau, Christoph; Guthe, Michael (The Eurographics Association and John Wiley & Sons Ltd., 2019)
    A mandatory component for many point set algorithms is the availability of consistently oriented vertex-normals (e.g. for surface reconstruction, feature detection, visualization). Previous orientation methods on meshes ...
  • High Quality Refinable G-splines for Locally Quad-dominant Meshes With T-gons 

    Karciauskas, Kestutis; Peters, Jorg (The Eurographics Association and John Wiley & Sons Ltd., 2019)
    Polyhedral modeling and re-meshing algorithms use T-junctions to add or remove feature lines in a quadrilateral mesh. In many ways this is akin to adaptive knot insertion in a tensor-product spline, but differs in that the ...
  • Feature Preserving Octree-Based Hexahedral Meshing 

    Gao, Xifeng; Shen, Hanxiao; Panozzo, Daniele (The Eurographics Association and John Wiley & Sons Ltd., 2019)
    We propose an octree-based algorithm to tessellate the interior of a closed surface with hexahedral cells. The generated hexahedral mesh (1) explicitly preserves sharp features of the original input, (2) has a maximal, ...
  • Unsupervised Cycle-consistent Deformation for Shape Matching 

    Groueix, Thibault; Fisher, Matthew; Kim, Vladimir G.; Russel, Bryan C.; Aubry, Mathieu (The Eurographics Association and John Wiley & Sons Ltd., 2019)
    We propose a self-supervised approach to deep surface deformation. Given a pair of shapes, our algorithm directly predicts a parametric transformation from one shape to the other respecting correspondences. Our insight is ...
  • Point Pattern Synthesis via Irregular Convolution 

    Tu, Peihan; Lischinski, Dani; Huang, Hui (The Eurographics Association and John Wiley & Sons Ltd., 2019)
    Point pattern synthesis is a fundamental tool with various applications in computer graphics. To synthesize a point pattern, some techniques have taken an example-based approach, where the user provides a small exemplar ...
  • A Convolutional Decoder for Point Clouds using Adaptive Instance Normalization 

    Lim, Isaak; Ibing, Moritz; Kobbelt, Leif (The Eurographics Association and John Wiley & Sons Ltd., 2019)
    Automatic synthesis of high quality 3D shapes is an ongoing and challenging area of research. While several data-driven methods have been proposed that make use of neural networks to generate 3D shapes, none of them reach ...
  • Structural Design Using Laplacian Shells 

    Ulu, Erva; McCann, Jim; Kara, Levent Burak (The Eurographics Association and John Wiley & Sons Ltd., 2019)
    We introduce a method to design lightweight shell objects that are structurally robust under the external forces they may experience during use. Given an input 3D model and a general description of the external forces, our ...
  • A Family of Barycentric Coordinates for Co-Dimension 1 Manifolds with Simplicial Facets 

    Yan, Zhipei; Schaefer, Scott (The Eurographics Association and John Wiley & Sons Ltd., 2019)
    We construct a family of barycentric coordinates for 2D shapes including non-convex shapes, shapes with boundaries, and skeletons. Furthermore, we extend these coordinates to 3D and arbitrary dimension. Our approach modifies ...
  • Hierarchical Functional Maps between Subdivision Surfaces 

    Shoham‬‏, ‪Meged; Vaxman, Amir; Ben-Chen, Mirela (The Eurographics Association and John Wiley & Sons Ltd., 2019)
    We propose a novel approach for computing correspondences between subdivision surfaces with different control polygons. Our main observation is that the multi-resolution spectral basis functions that are often used for ...
  • Structured Regularization of Functional Map Computations 

    Ren, Jing; Panine, Mikhail; Wonka, Peter; Ovsjanikov, Maks (The Eurographics Association and John Wiley & Sons Ltd., 2019)
    We consider the problem of non-rigid shape matching using the functional map framework. Specifically, we analyze a commonly used approach for regularizing functional maps, which consists in penalizing the failure of the ...
  • Dense Point-to-Point Correspondences Between Genus-Zero Shapes 

    Lee, Sing Chun; Kazhdan, Misha (The Eurographics Association and John Wiley & Sons Ltd., 2019)
    We describe a novel approach that addresses the problem of establishing correspondences between non-rigidly deformed shapes by performing the registration over the unit sphere. In a pre-processing step, each shape is ...
  • Consistent Shape Matching via Coupled Optimization 

    Azencot, Omri; Dubrovina, Anastasia; Guibas, Leonidas (The Eurographics Association and John Wiley & Sons Ltd., 2019)
    We propose a new method for computing accurate point-to-point mappings between a pair of triangle meshes given imperfect initial correspondences. Unlike the majority of existing techniques, we optimize for a map while ...
  • Divergence-Free Shape Correspondence by Deformation 

    Eisenberger, Marvin; Lähner, Zorah; Cremers, Daniel (The Eurographics Association and John Wiley & Sons Ltd., 2019)
    We present a novel approach for solving the correspondence problem between a given pair of input shapes with non-rigid, nearly isometric pose difference. Our method alternates between calculating a deformation field and a ...
