    • Computational Design and Optimization of Non-Circular Gears 

      Xu, Hao; Fu, Tianwen; Song, Peng; Zhou, Mingjun; Fu, Chi-Wing; Mitra, Niloy J. (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      We study a general form of gears known as non-circular gears that can transfer periodic motion with variable speed through their irregular shapes and eccentric rotation centers. To design functional non-circular gears is ...

    • Curve Complexity Heuristic KD-trees for Neighborhood-based Exploration of 3D Curves 

      Lu, Yucheng; Cheng, Luyu; Isenberg, Tobias; Fu, Chi-Wing; Chen, Guoning; Liu, Hui; Deussen, Oliver; Wang, Yunhai (The Eurographics Association and John Wiley & Sons Ltd., 2021)
      We introduce the curve complexity heuristic (CCH), a KD-tree construction strategy for 3D curves, which enables interactive exploration of neighborhoods in dense and large line datasets. It can be applied to searches of ...

    • Non-Local Low-Rank Normal Filtering for Mesh Denoising 

      Li, Xianzhi; Zhu, Lei; Fu, Chi-Wing; Heng, Pheng-Ann (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      This paper presents a non-local low-rank normal filtering method for mesh denoising. By exploring the geometric similarity between local surface patches on 3D meshes in the form of normal fields, we devise a low-rank ...

    • Worst-Case Rigidity Analysis and Optimization for Assemblies with Mechanical Joints 

      Liu, Zhenyuan; Hu, Jingyu; Xu, Hao; Song, Peng; Zhang, Ran; Bickel, Bernd; Fu, Chi-Wing (The Eurographics Association and John Wiley & Sons Ltd., 2022)
      We study structural rigidity for assemblies with mechanical joints. Existing methods identify whether an assembly is structurally rigid by assuming parts are perfectly rigid. Yet, an assembly identified as rigid may not ...
