    • Image Interpolation by Pixel-Level Data-Dependent Triangulation 

      Su, Dan; Willis, Philip (The Eurographics Association and Blackwell Publishing Ltd., 2004)
      We present a novel image interpolation algorithm. The algorithm can be used in arbitrary resolution enhancement, arbitrary rotation and other applications of still images in continuous space. High-resolution images are ...

    • An Integer One-Pass Algorithm for Voxel Traversal 

      Liu, Y. K.; Zalik, B.; Yang, H. (The Eurographics Association and Blackwell Publishing Ltd., 2004)
      Voxel traversing along a line in a uniformly divided voxel space is frequently needed in different applications of computer graphics. The paper presents a new integer one-pass algorithm for this problem. In 2D, the proposed ...

    • Modeling Trees with Hypertextures 

      Strnad, D.; Guid, N. (The Eurographics Association and Blackwell Publishing Ltd., 2004)
      In the paper, a new method for modelling trees at medium detail is presented. The method is based on a volumetric representation of trees, generated by an iterated function system (IFS). Alleviating the modeling restrictions ...

    • Space-Time Hierarchical Radiosity with Clustering and Higher-Order Wavelets 

      Damez, Cyrille; Holzschuch, Nicolas; Sillion, Francois X. (The Eurographics Association and Blackwell Publishing Ltd., 2004)
      We address in this paper the issue of computing diffuse global illumination solutions for animation sequences. The principal difficulties lie in the computational complexity of global illumination, emphasized by the movement ...

    • The State of the Art in Flow Visualization: Dense and Texture-Based Techniques 

      Laramee, Robert S.; Hauser, Helwig; Doleisch, Helmut; Vrolijk, Benjamin; Post, Frits H. and Weiskopf, Daniel (The Eurographics Association and Blackwell Publishing Ltd., 2004)
      Flow visualization has been a very attractive component of scientific visualization research for a long time. Usually very large multivariate datasets require processing. These datasets often consist of a large number of ...

    • A Viewpoint-Dependent Approach to Ray Trace Free-Form Surfaces 

      Formella, A.; Mueller, K. (The Eurographics Association and Blackwell Publishing Ltd., 2004)
      For convincing realistic scenes objects with free-form surfaces are essential. Especially for photorealistic rendering pure polygonal models are often not sufficient. We present a new kind of algorithm to render free-form ...

    • Visualizing Objects with Mirrors 

      Hurtado, F.; Noy, M.; Robert, J.-M.; Sacristan, V.; Skiena, S. (The Eurographics Association and Blackwell Publishing Ltd., 2004)
      We present an automatic camera and mirrors placement method for visualizing 3D scenes such that complete and nonredundant visibility is guaranteed, as well as highest image resolution. We provide algorithms and geometries ...
