  • Shapira, Nitzan; Ben-Chen, Mirela (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    Inferring maps between shapes is a long standing problem in geometry processing. The less similar the shapes are, the harder it is to compute a map, or even define criteria to evaluate it. In many cases, shapes appear as ...
  • Jin, Yao; Huang, Jin; Tong, Ruofeng (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    Constructing locally injective mappings for 2D triangular meshes is vital in applications such as deformations. In such a highly constrained optimization, the prescribed tessellation may impose strong restriction on the ...
  • Yoshiyasu, Yusuke; Ma, Wan-Chun; Yoshida, Eiichi; Kanehiro, Fumio (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    We present a non-rigid surface registration technique that can align surfaces with sizes and shapes that are different from each other, while avoiding mesh distortions during deformation. The registration is constrained ...
  • Azencot, Omri; Weißmann, Steffen; Ovsjanikov, Maks; Wardetzky, Max; Ben-Chen, Mirela (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    Fluid simulation plays a key role in various domains of science including computer graphics. While most existing work addresses fluids on bounded Euclidean domains, we consider the problem of simulating the behavior of an ...
  • Heeren, Behrend; Rumpf, Martin; Schröder, Peter; Wardetzky, Max; Wirth, Benedikt (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    We prove both in the smooth and discrete setting that the Hessian of an elastic deformation energy results in a proper Riemannian metric on the space of shells (modulo rigid body motions). Based on this foundation we develop ...
  • Kosinka, Jiri; Sabin, Malcolm A.; Dodgson, Neil A. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    We explore a method for generalising Pixar semi-sharp creases from the univariate cubic case to arbitrary degree subdivision curves. Our approach is based on solving simple matrix equations. The resulting schemes allow for ...
  • Deng, Chongyang; Hormann, Kai (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    Pseudo-splines provide a rich family of subdivision schemes with a wide range of choices that meet various demands for balancing the approximation power, the length of the support, and the regularity of the limit functions. ...
  • Mellado, Nicolas; Aiger, Dror; Mitra, Niloy J. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    Data acquisition in large-scale scenes regularly involves accumulating information across multiple scans. A common approach is to locally align scan pairs using Iterative Closest Point (ICP) algorithm (or its variants), ...
  • Schroers, Christopher; Setzer, Simon; Weickert, Joachim (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    The problem of reconstructing a watertight surface from a finite set of oriented points has received much attention over the last decades. In this paper, we propose a general higher order framework for surface reconstruction. ...
  • Jiang, Caigui; Wang, Jun; Wallner, Johannes; Pottmann, Helmut (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    Motivated by requirements of freeform architecture, and inspired by the geometry of hexagonal combs in beehives, this paper addresses torsion-free structures aligned with hexagonal meshes. Since repetitive geometry is a ...
  • Takayama, Kenshi; Panozzo, Daniele; Sorkine-Hornung, Olga (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    We propose an algorithm to quadrangulate an N-sided patch with prescribed numbers of edge subdivisions at its boundary. Our algorithm is guaranteed to succeed for arbitrary valid input, which is proved using a canonical ...
  • Yan, Dong-Ming; Guo, Jianwei; Jia, Xiaohong; Zhang, Xiaopeng; Wonka, Peter (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    In this paper, we present a novel method for surface sampling and remeshing with good blue-noise properties. Our approach is based on the farthest point optimization (FPO), a relaxation technique that generates high quality ...
  • AlHalawani, Sawsan; Yang, Yong-Liang; Wonka, Peter; Mitra, Niloy J. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    Urban data ranging from images and laser scans to traffic flows are regularly analyzed and modeled leading to better scene understanding. Commonly used computational approaches focus on geometric descriptors, both for ...
  • Sidorov, Kirill A.; Marshall, A. David (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    We present a new real-time approach to simulate deformable objects using a learnt statistical model to achieve a high degree of realism. Our approach improves upon state-of-the-art interactive shape-matching meshless ...
  • Tam, Gary K. L.; Martin, Ralph R.; Rosin, Paul L.; Lai, Yu-Kun (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    Identifying multiple deformable parts on meshes and establishing dense correspondences between them are tasks of fundamental importance to computer graphics, with applications to e.g. geometric edit propagation and texture ...
  • Litman, Roee; Bronstein, Alex; Bronstein, Michael; Castellani, Umberto (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    We present a method for supervised learning of shape descriptors for shape retrieval applications. Many contentbased shape retrieval approaches follow the bag-of-features (BoF) paradigm commonly used in text and image ...
  • Xu, Weiwei; Shi, Zhouxu; Xu, Mingliang; Zhou, Kun; Wang, Jingdong; Zhou, Bin; Wang, Jinrong; Yuan, Zhenming (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    We propose a transductive shape segmentation algorithm, which can transfer prior segmentation results in database to new shapes without explicitly specification of prior category information. Our method first partitions ...
  • Vanek, Juraj; Galicia, Jorge A. G.; Benes, Bedrich (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    We introduce an optimization framework for the reduction of support structures required by 3D printers based on Fused Deposition Modeling (FDM) technology. The printers need to connect overhangs with the lower parts of the ...
  • Rodolà, Emanuele; Bulò, Samuel Rota; Cremers, Daniel (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    We consider the problem of stable region detection and segmentation of deformable shapes. We pursue this goal by determining a consensus segmentation from a heterogeneous ensemble of putative segmentations, which are ...
  • Xie, Zhige; Xu, Kai; Liu, Ligang; Xiong, Yueshan (The Eurographics Association and John Wiley and Sons Ltd., 2014)
    We propose a fast method for 3D shape segmentation and labeling via Extreme Learning Machine (ELM). Given a set of example shapes with labeled segmentation, we train an ELM classifier and use it to produce initial segmentation ...
