      In this paper, we consider the problem of information transfer across shapes and propose an extension to the widely used functional map representation. Our main observation is that in addition to the vector space structure ...
    • Extended Narrow Band FLIP for Liquid Simulations 

      Sato, Takahiro; Wojtan, Chris; Thuerey, Nils; Igarashi, Takeo; Ando, Ryoichi (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      The Fluid Implicit Particle method (FLIP) reduces numerical dissipation by combining particles with grids. To improve performance, the subsequent narrow band FLIP method (NB-FLIP) uses a FLIP-based fluid simulation only ...
    • Fast Fluid Simulations with Sparse Volumes on the GPU
