    • Feature Preserving Octree-Based Hexahedral Meshing 

      Gao, Xifeng; Shen, Hanxiao; Panozzo, Daniele (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      We propose an octree-based algorithm to tessellate the interior of a closed surface with hexahedral cells. The generated hexahedral mesh (1) explicitly preserves sharp features of the original input, (2) has a maximal, ...
    • Field-aligned Quadrangulation for Image Vectorization 

      Wei, Guangshun; Zhou, Yuanfeng; Gao, Xifeng; Ma, Qian; Xin, Shiqing; He, Ying (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Image vectorization is an important yet challenging problem, especially when the input image has rich content. In this paper, we develop a novel method for automatically vectorizing natural images with feature-aligned ...
    • Hexahedral Meshing With Varying Element Sizes 

      Xu, Kaoji; Gao, Xifeng; Deng, Zhigang; Chen, Guoning (© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Hexahedral (or Hex‐) meshes are preferred in a number of scientific and engineering simulations and analyses due to their desired numerical properties. Recent state‐of‐the‐art techniques can generate high‐quality hex‐meshes. ...
