      Multi-perspective rendering has a variety of applications; examples include lens refraction, curved mirror re- flection, caustics, as well depiction and visualization. However, multi-perspective rendering is not yet practical ...
    • Visual Chatter in the Real World 

      Nayar, Shree K.; Krishnan, Gurunandan G. (The Eurographics Association, 2006)
      When a scene is lit by a source of light, the radiance of each point in the scene can be viewed as having two components, namely, direct and global. Recently, an efFIcient separation method has been proposed that uses high ...

      Guthe, Michael; Balázs, Ákos; Klein, Reinhard (The Eurographics Association, 2006)
      The most efficient general occlusion culling techniques are based on hardware accelerated occlusion queries. Although in many cases these techniques can considerably improve performance, they may still reduce efficiency ...
    • Texture Replacement of Garments in Monocular Video 

      Scholz, Volker; Magnor, Marcus (The Eurographics Association, 2006)

    • Warping and Partitioning for Low Error Shadow Maps 

      Lloyd, D. Brandon; Tuft, David; Yoon, Sung-eui; Manocha, Dinesh (The Eurographics Association, 2006)
      We evaluate several shadow map algorithms based on warping and partitioning using the maximum perspective aliasing error over the entire view frustum. With respect to our error metric, we show that a range of warping ...
    • Reconstruction of Volumetric Surface Textures for Real-Time Rendering 

      Magda, Sebastian; Kriegman, David (The Eurographics Association, 2006)
      Volumetric texturing is a popular technique for rendering rich 3-D detail when a polygonal surface representation would be ineffective. Although efficient algorithms for rendering volumetric textures have been known for ...
    • Antialiasing for Automultiscopic 3D Displays 

      Zwicker, Matthias; Matusik, Wojciech; Durand, Frédo; Pfister, Hanspeter (The Eurographics Association, 2006)
      Automultiscopic displays show stereoscopic images that can be viewed from any viewpoint without special glasses. They hold great promise for the future of television and digital entertainment. However, the image quality ...
    • Ambient Occlusion for Animated Characters 

      Kontkanen, Janne; Aila, Timo (The Eurographics Association, 2006)
      We present a novel technique for approximating ambient occlusion of animated objects. Our method automatically determines the correspondence between animation parameters and per-vertex ambient occlusion using a set of ...
    • Bidirectional Instant Radiosity 

      Segovia, Benjamin; Iehl, Jean Claude; Mitanchey, Richard; Péroche, Bernard (The Eurographics Association, 2006)
      This paper presents a new sampling strategy to achieve interactive global illumination on one commodity computer. The goal is to propose an efficient numerical stochastic scheme which can be well adapted to a fast rendering ...
    • Feature-Aware Texturing 

      Gal, Ran; Sorkine, Olga; Cohen-Or, Daniel (The Eurographics Association, 2006)
      We present a method for inhomogeneous 2D texture mapping guided by a feature mask, that preserves some regions of the image, such as foreground objects or other prominent parts. The method is able to arbitrarily warp a ...
    • Segmentation-Based 3D Artistic Rendering 

      Kolliopoulos, Alexander; Wang, Jack M.; Hertzmann, Aaron (The Eurographics Association, 2006)
      This paper introduces segmentation-based 3D non-photorealistic rendering, in which 3D scenes are rendered as a collection of 2D image segments. Segments abstract out unnecessary detail and provide a basis for defining new ...
    • Sequential Sampling for Dynamic Environment Map Illumination 

      Ghosh, Abhijeet; Doucet, Arnaud; Heidrich, Wolfgang (The Eurographics Association, 2006)
      Sampling complex illumination in the form of environment maps has received a lot of attention in computer graphics. Recent work in this area has demonstrated that drawing samples from the product of light and BRDF produces ...
