    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
    • Wavelet Environment Matting 

      Peers, Pieter; Dutré, Philip (The Eurographics Association, 2003)
      In this paper we present a novel approach for capturing the environment matte of a scene. We impose no restrictions on material properties of the objects in the captured scene and exploit scene characteristics (e.g. material ...
    • Interactive Global Illumination in Complex and Highly Occluded Environments 

      Wald, Ingo; Benthin, Carsten; Slusallek, Philipp (The Eurographics Association, 2003)
      Global illumination algorithms have traditionally been very time consuming and were only suitable for off-line computations. Recent research in realtime ray tracing has improved global illumination performance to allow for ...
    • Efficient Isotropic BRDF Measurement 

      Matusik, Wojciech; Pfister, Hanspeter; Brand, Matthew; McMillan, Leonard (The Eurographics Association, 2003)
      In this paper we present novel reflectance measurement procedures that require fewer total measurements than standard uniform sampling approaches. First, we acquire densely sampled reflectance data for a large collection ...
    • Refinement Criteria Based on f-Divergences 

      Rigau, Jaume; Feixas, Miquel; Sbert, Mateu (The Eurographics Association, 2003)
      In several domains a refinement criterion is often needed to decide whether to go on or to stop sampling a signal. When the sampled values are homogeneous enough, we assume that they represent the signal fairly well and ...
    • Interactive Texture Synthesis on Surfaces Using Jump Maps 

      Zelinka, Steve; Garland, Michael (The Eurographics Association, 2003)
      We introduce a new method for fast texture synthesis on surfaces from examples. We generalize the image-based jump map texture synthesis algorithm, which partitions the task of texture synthesis into a slower analysis phase ...
    • Efficient and Realistic Visualization of Cloth 

      Sattler, Mirko; Sarlette, Ralf; Klein, Reinhard (The Eurographics Association, 2003)
      Efficient and realistic rendering of cloth is of great interest especially in the context of e-commerce. Aside from the simulation of cloth draping, the rendering has to provide the "look and feel" of the fabric itself. ...
    • Optimizing Color Matching in a Lighting Reproduction System for Complex Subject and Illuminant Spectra 

      Wenger, A.; Hawkins, T.; Debevec, P. (The Eurographics Association, 2003)
      This paper presents a technique for improving color matching results in an LED-based lighting reproduction system for complex light source spectra. In our technique, we use measurements of the spectral response curve of ...
    • 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 ...
    • The Trilateral Filter for High Contrast Images and Meshes 

      Choudhury, Prasun; Tumblin, Jack (The Eurographics Association, 2003)
      We present a new, single-pass nonlinear filter for edge-preserving smoothing and visual detail removal for N dimensional signals in computer graphics, image processing and computer vision applications. Built from two ...
    • 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 ...
    • Interactive Rendering of Translucent Deformable Objects 

      Mertens, Tom; Kautz, Jan; Bekaert, Philippe; Seidel, Hans-Peter; Reeth, Frank Van (The Eurographics Association, 2003)
      Realistic rendering of materials such as milk, fruits, wax, marble, and so on, requires the simulation of subsurface scattering of light. This paper presents an algorithm for plausible reproduction of subsurface scattering ...
    • Rendering Fake Soft Shadows with Smoothies 

      Chan, Eric; Durand, Fredo (The Eurographics Association, 2003)
      We present a new method for real-time rendering of shadows in dynamic scenes. Our approach builds on the shadow map algorithm by attaching geometric primitives that we call "smoothies" to the objects' silhouettes. The ...
