  • 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 ...
  • Constructing 3D CSG Models from 3D Raw Point Clouds 

    Wu, Qiaoyun; Xu, Kai; Wang, Jun (The Eurographics Association and John Wiley & Sons Ltd., 2018)
    The Constructive Solid Geometry (CSG) tree, encoding the generative process of an object by a recursive compositional structure of bounded primitives, constitutes an important structural representation of 3D objects. ...
  • Möbius Registration 

    Baden, Alex; Crane, Keenan; Kazhdan, Misha (The Eurographics Association and John Wiley & Sons Ltd., 2018)
    Conformal parameterizations over the sphere provide high-quality maps between genus zero surfaces, and are essential for applications such as data transfer and comparative shape analysis. However, such maps are not unique: ...
  • Modular Latent Spaces for Shape Correspondences 

    Ganapathi-Subramanian, Vignesh; Diamanti, Olga; Guibas, Leonidas J. (The Eurographics Association and John Wiley & Sons Ltd., 2018)
    We consider the problem of transporting shape descriptors across shapes in a collection in a modular fashion, in order to establish correspondences between them. A common goal when mapping between multiple shapes is ...
  • 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 ...
  • Principal Geodesic Analysis in the Space of Discrete Shells 

    Heeren, Behrend; Zhang, Chao; Rumpf, Martin; Smith, William (The Eurographics Association and John Wiley & Sons Ltd., 2018)
    Important sources of shape variability, such as articulated motion of body models or soft tissue dynamics, are highly nonlinear and are usually superposed on top of rigid body motion which must be factored out. We propose ...
  • Field-Aligned and Lattice-Guided Tetrahedral Meshing 

    Ni, Saifeng; Zhong, Zichun; Huang, Jin; Wang, Wenping; Guo, Xiaohu (The Eurographics Association and John Wiley & Sons Ltd., 2018)
    We present a particle-based approach to generate field-aligned tetrahedral meshes, guided by cubic lattices, including BCC and FCC lattices. Given a volumetric domain with an input frame field and a user-specified edge ...

    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 ...
