    • QuadriFlow: A Scalable and Robust Method for Quadrangulation 

      Huang, Jingwei; Zhou, Yichao; Niessner, Matthias; Shewchuk, Jonathan Richard; Guibas, Leonidas J. (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      QuadriFlow is a scalable algorithm for generating quadrilateral surface meshes based on the Instant Field-Aligned Meshes of Jakob et al. (ACM Trans. Graph. 34(6):189, 2015). We modify the original algorithm such that it ...

    • Sensor-aware Normal Estimation for Point Clouds from 3D Range Scans 

      Comino Trinidad, Marc; Andujar, Carlos; Chica, Antonio; Brunet, Pere (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      Normal vectors are essential for many point cloud operations, including segmentation, reconstruction and rendering. The robust estimation of normal vectors from 3D range scans is a challenging task due to undersampling and ...

    • Statistical Modeling of the 3D Geometry and Topology of Botanical Trees 

      Wang, Guan; Laga, Hamid; Jia, Jinyuan; Xie, Ning; Tabia, Hedi (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      We propose a framework for statistical modeling of the 3D geometry and topology of botanical trees. We treat botanical trees as points in a tree-shape space equipped with a proper metric that captures the geometric and the ...

    • Topological Function Optimization for Continuous Shape Matching 

      Poulenard, Adrien; Skraba, Primoz; Ovsjanikov, Maks (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      We present a novel approach for optimizing real-valued functions based on a wide range of topological criteria. In particular, we show how to modify a given function in order to remove topological noise and to exhibit ...

    • A Unified Discrete Framework for Intrinsic and Extrinsic Dirac Operators for Geometry Processing 

      Ye, Zi; Diamanti, Olga; Tang, Chengcheng; Guibas, Leonidas J.; Hoffmann, Tim (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      Spectral mesh analysis and processing methods, namely ones that utilize eigenvalues and eigenfunctions of linear operators on meshes, have been applied to numerous geometric processing applications. The operator used ...
