    • Area-Preserving Parameterizations for Spherical Ellipses 

      Guillén, Ibón; Ureña, Carlos; King, Alan; Fajardo, Marcos; Georgiev, Iliyan; López-Moreno, Jorge; Jarabo, Adrián (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We present new methods for uniformly sampling the solid angle subtended by a disk. To achieve this, we devise two novel area-preserving mappings from the unit square [0;1]2 to a spherical ellipse (i.e. the projection of ...

    • Fiber-Level On-the-Fly Procedural Textiles 

      Luan, Fujun; Zhao, Shuang; Bala, Kavita (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Procedural textile models are compact, easy to edit, and can achieve state-of-the-art realism with fiber-level details. However, these complex models generally need to be fully instantiated (aka. realized) into 3D volumes ...

    • Stochastic Light Culling for VPLs on GGX Microsurfaces 

      Tokuyoshi, Yusuke; Harada, Takahiro (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      This paper introduces a real-time rendering method for single-bounce glossy caustics created by GGX microsurfaces. Our method is based on stochastic light culling of virtual point lights (VPLs), which is an unbiased culling ...
