    • Dependent Tests Driven Filtering in Monte-Carlo Global Illumination 

      Csonka, Ferenc; Szirmay-Kalos, Laszlo; Kelemen, Csaba; Antal, György (Eurographics Association, 2002)
      This paper presents a multi-phase algorithm to solve the global illumination problem. In the first phase dependent tests are applied, i.e. the random walks of different pixels are built from the same random numbers. The ...
    • Digital Watermarking for Volumetric Datasets 

      Dimitrov, Leonid I.; Sramek, Milos (Eurographics Association, 2002)
      An idea for digitaly watermarking volumetric datasets (VDS) and preliminary results from a test implementation are presented. It consists of a combination of filtering and rendering operations on volumetric data allowing ...
    • Distance fields applied to character animation 

      Rudomin, Isaac; Castillo, J. (Eurographics Association, 2002)
      A general hybrid geometric-physical method that is useful for animating characters with skin, clothing and a MPEG-4 compatible face is presented. This method uses an approximation to the underlying musculo-skeletal structure ...
    • Dynamic Motion Models 

      Grünvogel, Stefan Michael; Lange, Thorsten; Piesk, Jens (Eurographics Association, 2002)
      Real-time animation of virtual characters is a demanding task. We propose dynamic motion models which can create the motion of a virtual character in different styles and have the ability to change the animation while it ...
    • Dynamics-Based Motion Synthesis by Simple Learning Control 

      Kiriazov, Petko (Eurographics Association, 2002)
      Point-to-point motion of a humanoid agent (or any mobile creature) is considered as a composition of basic movements related to the degrees of freedom. With time/energy performance criteria, such movements can be synthesized ...
    • Eurographics 2002 - Presentation of European Groups doing Computer Graphics Research 

      - (Eurographics Association, 2002)
      This brochure contains a concentrated description of many European Computer Graphics research labs. It was produced to accompany a track of lab presentations at the annual conference Eurographics’2002 in Saarbrücken in ...
    • Extraction of Critical Points and Nets Based on Discrete Gradient Vector Field 

      De Floriani, Leila; Mesmoudi, Mohammed Mostefa; Danovaro, Emanuele (Eurographics Association, 2002)
      In this paper we address the problem of representing the topology of discrete scalar fields defined on triangulated domains. To this aim, we use the notion of discrete gradient vector field that we have introduced in [4] ...
    • Facial Modeling and Animation 

      Haber, Jörg; Magnenat-Thalmann, Nadia; Terzopoulos, Demetri; Vetter, Thomas; Blanz, Volker; Kähler, Kolja (Eurographics Association, 2002)
    • 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 ...
    • Feature Extraction and Visualisation of Flow Fields 

      Post, Frits H.; Vrolijk, Benjamin; Hauser, Helwig; Laramee, Robert S.; Doleisch, Helmut (Eurographics Association, 2002)
      Flow visualisation has already been a very attractive part of visualisation research for a long time. Usually very large data sets need to be processed, which often consist of multivariate data with a large number of sample ...
    • 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 ...
    • Flexible bump map capture from video 

      Paterson, James Alexander; Fitzgibbon, Andrew W. (Eurographics Association, 2002)
      We extend recent techniques for the automated capture of surface normal maps or bump maps from real-world material samples. In contrast to recent systems, which have required cumbersome laboratory setups with careful ...
    • Frame-Coherent Stippling 

      Meruvia Pastor, Oscar E.; Strothotte, Thomas (Eurographics Association, 2002)
      Stippling is an artistic rendering technique where shading and texture is given by placing points or stipples on the canvas until the desired darkness is achieved. Computer-generated stippling has focused on producing high ...
    • From Textual Chats to Interest Groups in 3D Virtual Space 

      Masa, Michal; Zara, Jiri (Eurographics Association, 2002)
      While the textual chat is a highly popular tool for various kinds of social interactions, its extension to the visual three-dimensional domain remains almost untouched and without practical utilization yet. This paper ...
    • Function-defined shape node for VRML 

      Lai, Feng Min; Sourin, Alexei (Eurographics Association, 2002)
      This paper describes how the web-based visualisation can be greatly improved using the function-based shape modelling technique. We propose the function-defined VRML shape node, which allows the content creators to describe ...
