    • Improved Corners with Multi‐Channel Signed Distance Fields 

      Chlumský, V.; Sloup, J.; Šimeček, I. (© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)
      We propose an extension to the state‐of‐the‐art text rendering technique based on sampling a 2D signed distance field from a texture. This extension significantly improves the visual quality of sharp corners, which is the ...

    • Super‐Resolution of Point Set Surfaces Using Local Similarities 

      Hamdi‐Cherif, Azzouz; Digne, Julie; Chaine, Raphaëlle (© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)
      Three‐dimensional scanners provide a virtual representation of object surfaces at some given precision that depends on many factors such as the object material, the quality of the laser ray or the resolution of the camera. ...

    • Uniformization and Density Adaptation for Point Cloud Data Via Graph Laplacian 

      Luo, Chuanjiang; Ge, Xiaoyin; Wang, Yusu (© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)
      Point cloud data is one of the most common types of input for geometric processing applications. In this paper, we study the point cloud density adaptation problem that underlies many pre‐processing tasks of points data. ...
