    • Rational Bézier Guarding 

      Khanteimouri, Payam; Mandad, Manish; Campen, Marcel (The Eurographics Association and John Wiley & Sons Ltd., 2022)
      We present a reliable method to generate planar meshes of nonlinear rational triangular elements. The elements are guaranteed to be valid, i.e. defined by injective rational functions. The mesh is guaranteed to conform ...

    • Precise High-order Meshing of 2D Domains with Rational Bézier Curves 

      Yang, Jinlin; Liu, Shibo; Chai, Shuangming; Liu, Ligang; Fu, Xiao-Ming (The Eurographics Association and John Wiley & Sons Ltd., 2022)
      We propose a novel method to generate a high-order triangular mesh for an input 2D domain with two key characteristics: (1) the mesh precisely conforms to a set of input piecewise rational domain curves, and (2) the geometric ...

    • Deterministic Linear Time for Maximal Poisson-Disk Sampling using Chocks without Rejection or Approximation 

      Mitchell, Scott A. (The Eurographics Association and John Wiley & Sons Ltd., 2022)
      We show how to sample uniformly within the three-sided region bounded by a circle, a radial ray, and a tangent, called a ''chock.'' By dividing a 2D planar rectangle into a background grid, and subtracting Poisson disks ...

      Zheng, Xinyang; Liu, Yang; Wang, Pengshuai; Tong, Xin (The Eurographics Association and John Wiley & Sons Ltd., 2022)
      We present a StyleGAN2-based deep learning approach for 3D shape generation, called SDF-StyleGAN, with the aim of reducing visual and geometric dissimilarity between generated shapes and a shape collection. We extend ...

    • PriFit: Learning to Fit Primitives Improves Few Shot Point Cloud Segmentation

      We present PRIFIT, a semi-supervised approach for label-efficient learning of 3D point cloud segmentation networks. PRIFIT combines geometric primitive fitting with point-based representation learning. Its key idea is to ...

    • Smooth Interpolating Curves with Local Control and Monotone Alternating Curvature 

      Binninger, Alexandre; Sorkine-Hornung, Olga (The Eurographics Association and John Wiley & Sons Ltd., 2022)
      We propose a method for the construction of a planar curve based on piecewise clothoids and straight lines that intuitively interpolates a given sequence of control points. Our method has several desirable properties that ...

    • Localized Shape Modelling with Global Coherence: An Inverse Spectral Approach 

      Pegoraro, Marco; Melzi, Simone; Castellani, Umberto; Marin, Riccardo; Rodolà, Emanuele (The Eurographics Association and John Wiley & Sons Ltd., 2022)
      Many natural shapes have most of their characterizing features concentrated over a few regions in space. For example, humans and animals have distinctive head shapes, while inorganic objects like chairs and airplanes are ...

    • Harmonic Shape Interpolation on Multiply-connected Planar Domains 

      Shi, Dongbo; Chen, Renjie (The Eurographics Association and John Wiley & Sons Ltd., 2022)
      Shape interpolation is a fundamental problem in computer graphics. Recently, there have been some interpolation methods developed which guarantee that the results are of bounded amount of geometric distortion, hence ensure ...

    • SGP 2022 CGF 41-5: Frontmatter 

      Campen, Marcel; Spagnuolo, Michela (The Eurographics Association and John Wiley & Sons Ltd., 2022)

    • Nested Papercrafts for Anatomical and Biological Edutainment 

      Schindler, Marwin; Korpitsch, Thorsten; Raidou, Renata Georgia; Wu, Hsiang-Yun (The Eurographics Association and John Wiley & Sons Ltd., 2022)
      In this paper, we present a new workflow for the computer-aided generation of physicalizations, addressing nested configurations in anatomical and biological structures. Physicalizations are an important component of ...

    • Misinformed by Visualization: What Do We Learn From Misinformative Visualizations? 

      Lo, Leo Yu-Ho; Gupta, Ayush; Shigyo, Kento; Wu, Aoyu; Bertini, Enrico; Qu, Huamin (The Eurographics Association and John Wiley & Sons Ltd., 2022)
      Data visualization is powerful in persuading an audience. However, when it is done poorly or maliciously, a visualization may become misleading or even deceiving. Visualizations give further strength to the dissemination ...
