    • Sample Based Visibility for Soft Shadows using Alias-free Shadow Maps 

      Sintorn, Erik; Eisemann, Elmar; Assarsson, Ulf (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper introduces an accurate real-time soft shadow algorithm that uses sample based visibility. Initially, we present a GPU-based alias-free hard shadow map algorithm that typically requires only a single render pass ...

    • ScribbleBoost: Adding Classification to Edge-Aware Interpolation of Local Image and Video Adjustments 

      Li, Y.; Adelson, E.; Agarwala, A. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      One of the most common tasks in image and video editing is the local adjustment of various properties (e.g., saturation or brightness) of regions within an image or video. Edge-aware interpolation of user-drawn scribbles ...

    • Sequential Monte Carlo Adaptation in Low-Anisotropy Participating Media 

      Pegoraro, Vincent; Wald, Ingo; Parker, Steven G. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper presents a novel method that effectively combines both control variates and importance sampling in a sequential Monte Carlo context. The radiance estimates computed during the rendering process are cached in a ...

    • Shallow Bounding Volume Hierarchies for Fast SIMD Ray Tracing of Incoherent Rays 

      Dammertz, H.; Hanika, J.; Keller, A. (The Eurographics Association and Blackwell Publishing Ltd, 2008)

    • Stylized Vector Art from 3D Models with Region Support 

      Eisemann, Elmar; Winnemoeller, Holger; Hart, John C.; Salesin, David (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We describe a rendering system that converts a 3D meshed model into the stylized 2D filled-region vector-art commonly found in clip-art libraries. To properly define filled regions, we analyze and combine accurate but ...

    • Table-driven Adaptive Importance Sampling 

      Cline, David; Adams, Daniel; Egbert, Parris (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Monte Carlo rendering algorithms generally rely on some form of importance sampling to evaluate the measurement equation. Most of these importance sampling methods only take local information into account, however, so the ...

    • Tensor Clustering for Rendering Many-Light Animations 

      Hasan, Milos; Velazquez-Armendariz, Edgar; Pellacini, Fabio; Bala, Kavita (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Rendering animations of scenes with deformable objects, camera motion, and complex illumination, including indirect lighting and arbitrary shading, is a long-standing challenge. Prior work has shown that complex lighting ...
