    • 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 ...
