    • Fast Volume Carving 

      Pyo, Soon Hyoung; Shin, Yeong Gil (Eurographics Association, 2002)
      In recent years, the volumetric scene representation has been widely used in the fields of computer graphics and computer vision. In computer graphics, the representation is used to visualize and reconstruct 3D internal ...

    • A Convolution-Based Algorithm for Animated Water Waves 

      Loviscach, Jörn (Eurographics Association, 2002)
      A non-linear partial differential equation solver is too sophisticated for computer graphics applications if they are only used to render effects like circular waves and ship wakes. We present an approach which simulates ...

    • Modeling Visual Attention in VR: Measuring the Accuracy of Predicted Scanpaths 

      Duchowski, Andrew; Marmitt, Gerd (Eurographics Association, 2002)
      Dynamic human vision is an important contributing factor to the design of perceptually-based Virtual Reality. A common strategy relies on either an implicit assumption or explicit measurement of gaze direction. Given the ...

    • Image Editing with Intelligent Paint 

      Reese, Jack; Barrett, William (Eurographics Association, 2002)
      Intelligent Paint provides a new tool for interactively selecting image objects or regions of interest, while simultaneously applying filters or effects directly to the selection(s). By coupling adaptive cost-ordered region ...

    • Multi-dimensional and Multi-scale Visualizer of Large XML Documents 

      Jacquemin, Christian; Jardino, Michele (Eurographics Association, 2002)
      3D-XV (3-Dimensional XML Visualizer) is an interactive graphical interface for accessing large structured documents. It relies on a geometrical model that combines a sequential organization and a hierarchical structure. ...

    • Knowledge-Based Representation of Cinematic Expression and its Application to Animation 

      Friedman, Doron; Feldman, Yishai (Eurographics Association, 2002)
      Camera control in virtual environments received growing attention recently, and some of the research turned to cinematography as a source for inspiration. Cinematic knowledge is a highly challenging domain for formalization. ...

    • Interpolating 2D Shape Hierarchically 

      Johan, Henry; Nishita, Tomoyuki (Eurographics Association, 2002)
      Shape interpolation has been widely used in the field of computer graphics for modeling and for creating visual effects. This paper presents a novel hierarchical method to interpolate between two 2D shapes. A hierarchical ...

    • Automatic Data Acquisition and Visualization for Usability Evaluation of Virtual Reality Systems 

      Holm, Roland; Priglinger, Markus; Stauder, Erwin; Volkert, J.; Wagner, R. (Eurographics Association, 2002)
      Evaluating the usability of a Virtual Reality system is a common practice nowadays. However, gathering and analyzing the necessary data are time-consuming tasks and sometimes involve inconvenient changes to the system. The ...

    • Interactive Polygonisation for Function-based Modelling 

      Sourin, Alexei; Levinski, Konstantin (Eurographics Association, 2002)
      This paper addresses interactive function-based shape modelling. Interactive modification of the function model with concurrent visualization of the respective polygonal mesh lets us provide both the interactivity and any ...

    • Feature interference in free form template matching 

      Song, Y.; Vergeest, J. S. M.; Horvath, I. (Eurographics Association, 2002)
      Template matching is a useful method in the reconstruction of free form surfaces. In this paper, matching of free form surfaces with parameterized templates is studied with the emphasis on feature interference. By their ...

    • Improved Bump Mapping by using Quadratic Vector Interpolation 

      Hast, Hans Anders; Barrera, Tony; Bengtsson, Ewert (Eurographics Association, 2002)
      Bump mapping is a technique that perturbs normals used in the illumination computation in order to make the surface appear rough or wrinkled. Standard graphics hardware linearly interpolates rotated vectors in the direction ...

    • Rendering of Japanese Artcraft 

      Durikovic, Roman; Kolchin, Kostantin; Ershov, Sergey (Eurographics Association, 2002)
      We present several methods for simulation of Japanese lacquer ware, a prominent Far East Asian handicraft art. We consider two most popular kinds of Japanese lacquer ware made by the makie and nashiji techniques. For ...

    • Rendering Artistic Line Drawings Using Off-the-Shelf 3-D Software 

      Loviscach, Jörn (Eurographics Association, 2002)
      Most commercial 3-D software packages used for animated films and still picture production offer merely rudimentary support for non-photorealistic rendering. However, nearly all of these packages possess interfaces which ...

    • Texture Minification using Quad-trees and Fipmaps 

      Bornik, Alexander; Ferko, Andrej (Eurographics Association, 2002)
      The paper extends the recently published methods for image reconstruction and texture minification using the generalized ripmap method, named fipmap, and quad-trees. Fipmap is based on the technique of partitioned iterated ...

    • Texture Mapping on Doo-Sabin Subdivision Surfaces Using Multiple Images 

      Huang, Zhiyong; Neo, Chee Seng (Eurographics Association, 2002)
      We propose a texture mapping method on subdivision surfaces using multiple images and have implemented it on Doo- Sabin scheme. At the beginning, one texture map is specified for each control mesh face respectively. In a ...

    • Tree balancing for mesh simplification 

      Grabner, Markus (Eurographics Association, 2002)
      In this paper, a tree balancing technique is presented that reduces the number of hierarchy levels in typical paircontraction based mesh simplification methods. A well-balanced hierarchy is essential for data structures ...

    • SAVANT: A new efficient approach to generating the visual hull 

      Lyons, Alex; Kotcheff, Aaron (Eurographics Association, 2002)
