    • 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 ...
    • Automatic Modeling of Urban Facades from Raw LiDAR Point Data 

      Wang, Jun; Xu, Yabin; Remil, Oussama; Xie, Xingyu; Ye, Nan; Wei, Mingqiang (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Modeling of urban facades from raw LiDAR point data remains active due to its challenging nature. In this paper, we propose an automatic yet robust 3D modeling approach for urban facades with raw LiDAR point clouds. The ...
    • Building Construction Sets by Tiling Grammar Simplification 

      Kalojanov, Javor; Wand, Michael; Slusallek, Philipp (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      This paper poses the problem of fabricating physical construction sets from example geometry: A construction set provides a small number of different types of building blocks from which the example model as well as many ...
    • 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 ...
    • Efficient Volumetric PolyCube-Map Construction 

      Fu, Xiao-Ming; Bai, Chong-Yang; Liu, Yang (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      PolyCubes provide compact representations for closed complex shapes and are essential to many computer graphics applications. Existing automatic PolyCube construction methods usually suffer from poor quality or time-consuming ...
    • An Eulerian Approach for Constructing a Map Between Surfaces With Different Topologies 

      Park, Hangil; Cho, Youngjin; Bang, Seungbae; Lee, Sung-Hee (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      3D objects of the same kind often have different topologies, and finding correspondence between them is important for operations such as morphing, attribute transfer, and shape matching. This paper presents a novel method ...
    • Learning 3D Deformation of Animals from 2D Images 

      Kanazawa, Angjoo; Kovalsky, Shahar; Basri, Ronen; Jacobs, David (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Understanding how an animal can deform and articulate is essential for a realistic modification of its 3D model. In this paper, we show that such information can be learned from user-clicked 2D images and a template 3D ...
    • 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 ...
    • 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 ...
    • 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 ...
    • Spatial Matching of Animated Meshes 

      Seo, Hyewon; Cordier, Frederic (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      This paper presents a new technique which makes use of deformation and motion properties between animated meshes for finding their spatial correspondences. Given a pair of animated meshes exhibiting a semantically similar ...
