      Pie and doughnut charts nicely convey the part–whole relationship and they have become the most recognizable chart types for representing proportions in business and data statistics. Many experiments have been carried out ...
    • Direct Position‐Based Solver for Stiff Rods 

      Deul, Crispin; Kugelstadt, Tassilo; Weiler, Marcel; Bender, Jan (© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)
      In this paper, we present a novel direct solver for the efficient simulation of stiff, inextensible elastic rods within the position‐based dynamics (PBD) framework. It is based on the XPBD algorithm, which extends PBD to ...
    • Viewing Visual Analytics as Model Building
