      Ahmed, Amr Adel Hassan; Hilton, Adrian; Mokhtarian, Farzin (Eurographics Association, 2002)
      In this paper we introduce an adaptive motion compression technique using the discrete wavelet transform. Based on the analysis of human animation data, and its frequency contents, the wavelet analysis is utilised to achieve ...
    • Adaptive Tessellation for Trimmed NURBS Surface 

      YingLiang, Ma; Hewitt, Terry (Eurographics Association, 2002)
      We present an adaptive method for tessellating the trimmed NURBS surface in the parametric domain. Given a model space tolerance ε, the algorithm first splits the NURBS surface in both the U and V directions to fit within ...

      Terzopoulos, Demetri (Eurographics Association, 2002)
      The confluence of virtual reality and artificial life, an emerging discipline that spans the computational and biological sciences, has yielded synthetic worlds inhabited by realistic, artificial flora and fauna. Artificial ...
    • Automated Enhancement of 3D Models 

      Torres-Mendez, L.A.; Dudek, G. (Eurographics Association, 2002)
      The acquisition of a 3D model of a real environment can be accomplished using range sensors. In practice, suitable sensors to densely cover a large environment are often impractical. This paper presents ongoing work on the ...
    • 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 ...
    • Cloth Animation and Rendering 

      Hauth, Michael; Etzmuss, Olaf; Eberhardt, Bernd; Klein, Reinhard; Sarlette, Ralf; Sattler, Mirko; Daubert, Katja; Kautz, Jan (Eurographics Association, 2002)
      The area of physically-based modeling is situated in the intersection of computer science, mathematics, and physics. The animation of cloth is a particularly interesting application of physically-based modeling, because ...
    • Concise Tour to the Virtual Old Prague 

      Zara, Jiri (Eurographics Association, 2002)
      This paper describes a structure and a user interface of the Internet based 3D presentation of existing historical part of city Prague. The application offers a smooth tour to selected regions of the real city, utilizing ...
    • 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 ...
    • 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 ...
