    • Fast Texture Synthesis on Arbitrary Meshes 

      Magda, Sebastian; Kriegman, David (The Eurographics Association, 2003)
      While texture synthesis on surfaces has received much attention in computer graphics, the ideal solution that quickly produces high-quality textures with little user intervention has remained elusive. The algorithm presented ...
    • Hybrid Texture Synthesis 

      Nealen, Andrew; Alexa, Marc (The Eurographics Association, 2003)
      Patch-based texture synthesis algorithms produce reasonable results for a wide variety of texture classes. They preserve global structure, but often introduce unwanted visual artifacts along patch boundaries. Pixel-based ...
    • An Efficient Spatio-Temporal Architecture for Animation Rendering 

      Havran, Vlastimil; Damez, Cyrille; Myszkowski, Karol; Seidel, Hans-Peter (The Eurographics Association, 2003)
      Producing high quality animations featuring rich object appearance and compelling lighting effects is very time consuming using traditional frame-by-frame rendering systems. In this paper we present a rendering architecture ...
    • Path Integration for Light Transport in Volumes 

      Premoze, Simon; Ashikhmin, Michael; Shirley, Peter (The Eurographics Association, 2003)
      Simulating the transport of light in volumes such as clouds or objects with subsurface scattering is computationally expensive. We describe an approximation to such transport using path integration. Unlike the more commonly ...
    • Efficient Illumination by High Dynamic Range Images 

      Kollig, Thomas; Keller, Alexander (The Eurographics Association, 2003)
      We present an algorithm for determining quadrature rules for computing the direct illumination of predominantly diffuse objects by high dynamic range images. The new method precisely reproduces fine shadow detail, is much ...
    • Global Illumination Animation with Random Radiance Representation 

      Szirmay-Kalos, László; Antal, György; Benedek, Balázs (The Eurographics Association, 2003)
      This paper proposes a non-diffuse global illumination algorithm that is fast enough to be appropriate for interactive walkthroughs and general animations. To meet the severe performance requirements, we heavily exploit ...
    • A Stained Glass Image Filter 

      Mould, David (The Eurographics Association, 2003)
      Medieval stained glass windows are a stylized artform that has not previously been thoroughly treated in the computer graphics literature. In this paper, we present an automated method for transforming an arbitrary image ...
    • Delivering Interactivity to Complex Tone Mapping Operators 

      Artusi, Alessandro; Bittner, Jirí; Wimmer, Michael; Wilkie, Alexander (The Eurographics Association, 2003)
      The accurate display of high dynamic range images requires the application of complex tone mapping operators. These operators are computationally costly, which prevents their usage in interactive applications. We propose ...
    • Interactive Time-Dependent Tone Mapping Using Programmable Graphics Hardware 

      Goodnight, Nolan; Wang, Rui; Woolley, Cliff; Humphreys, Greg (The Eurographics Association, 2003)
      Modern graphics architectures have replaced stages of the graphics pipeline with fully programmable modules. Therefore, it is now possible to perform fairly general computation on each vertex or fragment in a scene. In ...
    • Computer Generated Celtic Design 

      Kaplan, Matthew; Cohen, Elaine (The Eurographics Association, 2003)
      We present a technique for automating the construction of Celtic knotwork and decorations similar to those in illuminated manuscripts such as the Lindisfarne Gospels. Our method eliminates restrictions imposed by previous ...
