      Yamamoto, Kazuhiko; Igarashi, Takeo (The Eurographics Association, 2016)
      Physically-based sound rendering enriches 3D animation. However, it is difficult to make an object with a given shape produce a specific sound using physically-based sound rendering because the user would need to define ...

      Canezin, Florian; Guennebaud, Gaël; Barthe, Loïc (The Eurographics Association, 2016)
      Particle based simulations are widely used in computer graphics. In this field, several recent results have improved the simulation itself or improved the tension of the final fluid surface. In current particle based ...
