    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 ...

    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 ...
  • 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 ...

    Bukenberger, Dennis R.; Lensch, Hendrik P. A. (The Eurographics Association and John Wiley & Sons Ltd., 2018)
    In this paper we present a novel method to reconstruct watertight quad meshes on scanned 3D geometry. There exist many different approaches to acquire 3D information from real world objects and sceneries. Resulting point ...
