    • Anisotropic Filtering of Non-Linear Surface Features 

      Hildebrandt, Klaus; Polthier, Konrad (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      A new method for noise removal of arbitrary surfaces meshes is presented which focuses on the preservation and sharpening of non-linear geometric features such as curved surface regions and feature lines. Our method uses ...
    • Applied Geometry:Discrete Differential Calculus for Graphics 

      Desbrun, Mathieu (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      Geometry has been extensively studied for centuries, almost exclusively from a differential point of view. However, with the advent of the digital age, the interest directed to smooth surfaces has now partially shifted due ...
    • Approximate Soft Shadows win an Image-Space Flood-Fill Algorithm 

      Arvo, Jukka; Hirvikorpi, Mika; Tyystjaervi, Joonas (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      Most former soft shadow algorithms have either suffered from restricted self-shadowing capabilities, been too slow for interactive applications, or could only be used with a limited types of geometry. In this paper, we ...
    • Approximated Centroidal Voronoi Diagrams for Uniform Polygonal Mesh Coarsening 

      Valette, Sebastien; Chassery, Jean-Marc (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      We present a novel clustering algorithm for polygonal meshes which approximates a Centroidal Voronoi Diagram construction. The clustering provides an efficient way to construct uniform tessellations, and therefore leads ...
    • Approximation of Optimal Voxel Size for Collision Detection in Maintainability Simulations within Massive Virtual Environments 

      Borro, D.; Garcia-Alonso, A.; Matey, L. (The Eurographics Association and Blackwell Publishing Ltd., 2004)
      This paper describes a Collision Method for massive virtual environments composed of millions of triangles. It has been applied in the aeronautics industry for maintainability simulations using virtual aircraft engine ...
    • Author Index Volume 23 (2004) 

      Unknown author (The Eurographics Association and Blackwell Publishing Ltd., 2004)
    • Balancing Considered Harmful - Faster Photon Mapping using the Voxel Volume Heuristic - 

      Wald, Ingo; Guenther, Johannes; Slusallek, Philipp (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      Photon mapping is one of the most important algorithms for computing global illumination. Especially for efficiently producing convincing caustics, there are no real alternatives to photon mapping. On the other hand, photon ...
    • A Biophysically-Based Spectral Model of Light Interaction with Human Skin 

      Krishnaswamy, Aravind; Baranoski, Gladimir V.G. (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      Despite the notable progress in physically-based rendering, there is still a long way to go before we can automatically generate predictable images of biological materials. In this paper, we address an open problem in this ...
    • CGForum 2004 Cover Image 

      Unknown author (The Eurographics Association and Blackwell Publishing Ltd., 2004)
    • Coherent Hierarchical Culling: Hardware Occlusion Queries Made Useful 

      Bittner, Jiri; Wimmer, Michael; Piringer, Harald; Purgathofer, Werner (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      We present a simple but powerful algorithm for optimizing the usage of hardware occlusion queries in arbitrary complex scenes. Our method minimizes the number of issued queries and reduces the delays due to the latency of ...
    • Combined Correlated and Importance Sampling in Direct Light Source Computation and Environment Mapping 

      Szecsi, Laszlo; Sbert, Mateu; Szirmay-Kalos, Laszlo (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      This paper presents a general variance reduction method that is a quasi-optimal combination of correlated and importance sampling. The weights of the combination are selected automatically in order to keep the merits of ...
    • Compression of Large-Scale Terrain Data for Real-Time Visualization Using a Tiled Quad Tree 

      Platings, M.; Day, A. M. (The Eurographics Association and Blackwell Publishing Ltd., 2004)
      The aim of the rapid world modeling project is to implement a system to visualize the topography of the entire world on consumer-level hardware. This presents a significant problem in terms of both storage requirements and ...
