    • Matting and Compositing for Fresnel Reflection on Wavy Surfaces 

      Endo, Yuki; Kanamori, Yoshihiro; Fukui, Yukio; Mitani, Jun (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      This paper introduces a framework that can extract an alpha matte from a single image with Fresnel reflection, and that can composite other objects with the image such that plausible reflections are included. Our method ...
    • Parameterization-Aware MIP-Mapping 

      Manson, Josiah; Schaefer, Scott (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      We present a method of generating mipmaps that takes into account the distortions due to the parameterization of a surface. Existing algorithms for generating mipmaps assume that the texture is isometrically mapped to the ...
    • Per-Vertex Defocus Blur for Stochastic Rasterization 

      Munkberg, Jacob; Toth, Robert; Akenine-Möller, Tomas (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      We present user-controllable and plausible defocus blur for a stochastic rasterizer. We modify circle of confusion coefficients per vertex to express more general defocus blur, and show how the method can be applied to ...
    • Polynomial Optics: A Construction Kit for Efficient Ray-Tracing of Lens Systems 

      Hullin, Matthias B.; Hanika, Johannes; Heidrich, Wolfgang (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Simulation of light transport through lens systems plays an important role in graphics. While basic imaging properties can be conveniently derived from linear models (like ABCD matrices), these approximations fail to ...
    • Pre-convolved Radiance Caching 

      Scherzer, Daniel; Nguyen, Chuong; Ritschel, Tobias; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      The incident indirect light over a range of image pixels is often coherent. Two common approaches to exploit this inter-pixel coherence to improve rendering performance are Irradiance Caching and Radiance Caching. Both ...
    • Preface and Table of Contents 

      Fredo Durand and Diego Gutierrez (The Eurographics Association and Blackwell Publishing Ltd., 2012)
    • Progressive Virtual Beam Lights 

      Novák, Jan; Nowrouzezahrai, Derek; Dachsbacher, Carsten; Jarosz, Wojciech (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      A recent technique that forms virtual ray lights (VRLs) from path segments in media, reduces the artifacts common to VPL approaches in participating media, however, distracting singularities still remain. We present Virtual ...
    • Quantized Point-Based Global Illumination 

      Buchholz, Bert; Boubekeur, Tamy (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Point-based global illumination (PBGI) uses a dense point sampling of the scene's surfaces to approximate indirect light transport and is intensively used in 3D motion pictures and special effects. Each point caches the ...
    • A Statistical Method for SVBRDF Approximation from Video Sequences in General Lighting Conditions 

      Palma, Gianpaolo; Callieri, Marco; Dellepiane, Matteo; Scopigno, Roberto (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      We present a statistical method for the estimation of the Spatially Varying Bidirectional Reflectance Distribution Function (SVBRDF) of an object with complex geometry, starting from video sequences acquired with fixed but ...
    • A Stylized Approach for Pencil Drawing from Photographs 

      Yang, Heekyung; Kwon, Yunmi; Min, Kyungha (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      We present a stylized scheme that produces pencil drawings in a range of styles from an image. To produce controllable pencil drawing effects and remedy the problems of existing convolution-based schemes, we develop a swing ...
    • Surface Relief Analysis for Illustrative Shading 

      Ammann, Lucas; Barla, Pascal; Guennebaud, Gaël; Granier, Xavier; Reuter, Patrick (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      In this paper, we present an analysis technique that leverages the complexity found in detailed 3D models for illustrative shading purposes. Given a smooth base surface with relief, it locates relief features (concavities, ...
    • Tessellation-Independent Smooth Shadow Boundaries 

      Mattausch, Oliver; Scherzer, Daniel; Wimmer, Michael; Igarashi, Takeo (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      We propose an efficient and light-weight solution for rendering smooth shadow boundaries that do not reveal the tessellation of the shadow-casting geometry. Our algorithm reconstructs the smooth contours of the underlying ...
