    • Customized Summarizations of Visual Data Collections 

      Yuan, Mengke; Ghanem, Bernard; Yan, Dong‐Ming; Wu, Baoyuan; Zhang, Xiaopeng; Wonka, Peter (© 2021 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2021)
      We propose a framework to generate customized summarizations of visual data collections, such as collections of images, materials, 3D shapes, and 3D scenes. We assume that the elements in the visual data collections can ...

    • Deep Deformation Detail Synthesis for Thin Shell Models 

      Chen, Lan; Gao, Lin; Yang, Jie; Xu, Shibiao; Ye, Juntao; Zhang, Xiaopeng; Lai, Yu-Kun (The Eurographics Association and John Wiley & Sons Ltd., 2023)
      In physics-based cloth animation, rich folds and detailed wrinkles are achieved at the cost of expensive computational resources and huge labor tuning. Data-driven techniques make efforts to reduce the computation significantly ...

    • Learning Scene Illumination by Pairwise Photos from Rear and Front Mobile Cameras 

      Cheng, Dachuan; Shi, Jian; Chen, Yanyun; Deng, Xiaoming; Zhang, Xiaopeng (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      Illumination estimation is an essential problem in computer vision, graphics and augmented reality. In this paper, we propose a learning based method to recover low-frequency scene illumination represented as spherical ...

    • Tree Branch Level of Detail Models for Forest Navigation 

      Zhang, Xiaopeng; Bao, Guanbo; Meng, Weiliang; Jaeger, Marc; Li, Hongjun; Deussen, Oliver; Chen, Baoquan (© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We present a level of detail (LOD) method designed for tree branches. It can be combined with methods for processing tree foliage to facilitate navigation through large virtual forests. Starting from a skeletal representation ...

    • Tree Growth Modelling Constrained by Growth Equations 

      Yi, Lei; Li, Hongjun; Guo, Jianwei; Deussen, Oliver; Zhang, Xiaopeng (© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)
      Modelling and simulation of tree growth that is faithful to the living environment and numerically consistent to botanic knowledge are important topics for realistic modelling in computer graphics. The realism factors ...
