    • Fast Out-of-Core Octree Generation for Massive Point Clouds 

      Schütz, Markus; Ohrhallinger, Stefan; Wimmer, Michael (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      We propose an efficient out-of-core octree generation method for arbitrarily large point clouds. It utilizes a hierarchical counting sort to quickly split the point cloud into small chunks, which are then processed in ...

    • Cosserat Rod with rh-Adaptive Discretization 

      Wen, Jiahao; Chen, Jiong; Nobuyuki, Umetani; Bao, Hujun; Huang, Jin (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Rod-like one-dimensional elastic objects often exhibit complex behaviors which pose great challenges to the discretization method for pursuing a faithful simulation. By only moving a small portion of material points, the ...

    • Semi-analytical Solid Boundary Conditions for Free Surface Flows 

      Chang, Yue; Liu, Shusen; He, Xiaowei; Li, Sheng; Wang, Guoping (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      The treatment of solid boundary conditions remains one of the most challenging parts in the SPH method. We present a semianalytical approach to handle complex solid boundaries of arbitrary shape. Instead of calculating a ...

    • Simulation of Arbitrarily-shaped Magnetic Objects 

      Kim, Seung-wook; Han, JungHyun (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Abstract We propose a novel method for simulating rigid magnets in a stable way. It is based on analytic solutions of the magnetic vector potential and flux density, which make the magnetic forces and torques calculated ...

    • A Novel Plastic Phase-Field Method for Ductile Fracture with GPU Optimization 

      Zhao, Zipeng; Huang, Kemeng; Li, Chen; Wang, Changbo; Qin, Hong (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      efficiently simulate ductile fracture with GPU optimization. At the theoretical level of physically-based modeling and simulation, our PPF approach assumes the fracture sensitivity of the material increases with the plastic ...

    • Fracture Patterns Design for Anisotropic Models with the Material Point Method 

      Cao, Wei; Lyu, Luan; Ren, Xiaohua; Zhang, Bob; Yang, Zhixin; Wu, Enhua (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Physically plausible fracture animation is a challenging topic in computer graphics. Most of the existing approaches focus on the fracture of isotropic materials. We proposed a frame-field method for the design of anisotropic ...

    • Learning Elastic Constitutive Material and Damping Models 

      Wang, Bin; Deng, Yuanmin; Kry, Paul; Ascher, Uri; Huang, Hui; Chen, Baoquan (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Commonly used linear and nonlinear constitutive material models in deformation simulation contain many simplifications and only cover a tiny part of possible material behavior. In this work we propose a framework for ...

    • Adjustable Constrained Soft-Tissue Dynamics 

      Wang, Bohan; Zheng, Mianlun; Barbic, Jernej (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Physically based simulation is often combined with geometric mesh animation to add realistic soft-body dynamics to virtual characters. This is commonly done using constraint-based simulation whereby a soft-tissue simulation ...

    • Image-Driven Furniture Style for Interactive 3D Scene Modeling 

      Weiss, Tomer; Yildiz, Ilkay; Agarwal, Nitin; Ataer-Cansizoglu, Esra; Choi, Jae-Woo (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Creating realistic styled spaces is a complex task, which involves design know-how for what furniture pieces go well together. Interior style follows abstract rules involving color, geometry and other visual elements. ...

    • Robust Computation of 3D Apollonius Diagrams 

      Wang, Peihui; Yuan, Na; Ma, Yuewen; Xin, Shiqing; He, Ying; Chen, Shuangmin; Xu, Jian; Wang, Wenping (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Apollonius diagrams, also known as additively weighted Voronoi diagrams, are an extension of Voronoi diagrams, where the weighted distance is defined by the Euclidean distance minus the weight. The bisectors of Apollonius ...

    • A Deep Residual Network for Geometric Decontouring 

      Ji, Zhongping; Zhou, Chengqin; Zhang, Qiankan; Zhang, Yu-Wei; Wang, Wenping (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Grayscale images are intensively used to construct or represent geometric details in field of computer graphics. In practice, displacement mapping technique often allows an 8-bit grayscale image input to manipulate the ...

    • Practical Fabrication of Discrete Chebyshev Nets 

      Liu, Hao-Yu; Liu, Zhong-Yuan; Zhao, Zheng-Yu; Liu, Ligang; Fu, Xiao-Ming (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      We propose a computational and practical technique to allow home users to fabricate discrete Chebyshev nets for various 3D models. The success of our method relies on two key components. The first one is a novel and simple ...

    • Memory-Efficient Bijective Parameterizations of Very-Large-Scale Models 

      Ye, Chunyang; Su, Jian-Ping; Liu, Ligang; Fu, Xiao-Ming (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      As high-precision 3D scanners become more and more widespread, it is easy to obtain very-large-scale meshes containing at least millions of vertices. However, processing these very-large-scale meshes is still a very ...
