Recent Submissions

  • Viitanen, Timo; Koskela, Matias; Jääskeläinen, Pekka; Immonen, Kalle; Takala, Jarmo (The Eurographics Association and John Wiley & Sons Ltd., 2017)
    There is recent interest in GPU architectures designed to accelerate ray tracing, especially on mobile systems with limited memory bandwidth. A promising recent approach is to store and traverse Bounding Volume Hierarchies ...

    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 ...
  • Wu, Lifan; Yan, Ling-Qi; Kuznetsov, Alexandr; Ramamoorthi, Ravi (The Eurographics Association and John Wiley & Sons Ltd., 2017)
    Distribution effects such as diffuse global illumination, soft shadows and depth of field, are most accurately rendered using Monte Carlo ray or path tracing. However, physically accurate algorithms can take hours to ...
  • Boughida, Malik; Boubekeur, Tamy (The Eurographics Association and John Wiley & Sons Ltd., 2017)
    The stochastic nature of Monte Carlo rendering algorithms inherently produces noisy images. Essentially, three approaches have been developed to solve this issue: improving the ray-tracing strategies to reduce pixel variance, ...
  • 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 ...
  • Guingo, Geoffrey; Sauvage, Basile; Dischler, Jean-Michel; Cani, Marie-Paule (The Eurographics Association and John Wiley & Sons Ltd., 2017)
    We propose a bi-layer representation for textures which is suitable for on-the-fly synthesis of unbounded textures from an input exemplar. The goal is to improve the variety of outputs while preserving plausible small-scale ...
  • Simon, Florian; Hanika, Johannes; Zirr, Tobias; Dachsbacher, Carsten (The Eurographics Association and John Wiley & Sons Ltd., 2017)
    Emissive media are often challenging to render: in thin regions where only few scattering events occur the emission is poorly sampled, while sampling events for emission can be disadvantageous due to absorption in dense ...
  • Müller, Thomas; Gross, Markus; Novák, Jan (The Eurographics Association and John Wiley & Sons Ltd., 2017)
    We present a robust, unbiased technique for intelligent light-path construction in path-tracing algorithms. Inspired by existing path-guiding algorithms, our method learns an approximate representation of the scene's ...
  • Singh, Gurprit; Miller, Bailey; Jarosz, Wojciech (The Eurographics Association and John Wiley & Sons Ltd., 2017)
    Recently researchers have started employing Monte Carlo-like line sample estimators in rendering, demonstrating dramatic reductions in variance (visible noise) for effects such as soft shadows, defocus blur, and participating ...
  • Nalbach, Oliver; Arabadzhiyska, Elena; Mehta, Dushyant; Seidel, Hans-Peter; Ritschel, Tobias (The Eurographics Association and John Wiley & Sons Ltd., 2017)
    In computer vision, convolutional neural networks (CNNs) achieve unprecedented performance for inverse problems where RGB pixel appearance is mapped to attributes such as positions, normals or reflectance. In computer ...
  • 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 ...

    Reproducing the appearance of real-world materials using current printing technology is problematic. The reduced number of inks available define the printer's limited gamut, creating distortions in the printed appearance ...

    Accurately modeling how light interacts with cloth is challenging, due to the volumetric nature of cloth appearance and its multiscale structure, where microstructures play a major role in the overall appearance at higher ...
  • Xu, Chao; Wang, Rui; Zhao, Shuang; Bao, Hujun (The Eurographics Association and John Wiley & Sons Ltd., 2017)
    We present a new technique to jointly MIP-map BRDF and normal maps. Starting with generating an instant BRDF map, our technique builds its MIP-mapped versions based on a highly efficient algorithm that interpolates von ...
  • Innamorati, Carlo; Ritschel, Tobias; Weyrich, Tim; Mitra, Niloy J. (The Eurographics Association and John Wiley & Sons Ltd., 2017)
    Photographers routinely compose multiple manipulated photos of the same scene into a single image, producing a fidelity difficult to achieve using any individual photo. Alternately, 3D artists set up rendering systems to ...
  • Leimkühler, Thomas; Seidel, Hans-Peter; Ritschel, Tobias (The Eurographics Association and John Wiley & Sons Ltd., 2017)
    Observing that many visual effects (depth-of-field, motion blur, soft shadows, spectral effects) and several sampling modalities (time, stereo or light fields) can be expressed as a sum of many pinhole camera images, we ...
