    • Real-time Animation of Dressed Virtual Humans 

      Cordier, Frederic; Magnenat-Thalmann, Nadia (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      In this paper, we describe a method for cloth animation in real-time. The algorithm works in a hybrid manner exploiting the merits of both the physical-based and geometric deformations. It makes use of predetermined ...

    • Recent Advances in Mesh Morphing 

      Alexa, Marc (Blackwell Publishers Ltd and the Eurographics Association, 2002)
      Meshes have become a widespread and popular representation of models in computer graphics. Morphing techniques aim at transforming a given source shape into a target shape. Morphing techniques have various applications ...

    • Representation of Pseudo Inter-reflection and Transparency by Considering Characteristics of Human Vision 

      Matsuoka, H.; Takeuchi, T.; Kitazawa, H.; Onozawa, A. (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      We have succeeded in developing a quick and fully automated system that can generate photo-realistic 3D CG data based on a real object. A major factor in this success comes from our findings through psychophysical experiments ...

    • Sculpturing on Discrete Displacement Fields 

      Ayasse, Jorg; Muller, Heinrich (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      A displacement field can be defined by a vector field and a height field on an orientable surfaceS, describing the direction and the amount of displacement to be applied toSin order to get a surface represented by the ...

      Unknown author (Blackwell Publishers Ltd and the Eurographics Association, 2002)

    • Siggraph 2002 

      Laycock, Stephen D.; Laycock, Robert G. (Blackwell Publishers, Inc and the Eurographics Association, 2002)

    • A Simple and Robust Mutation Strategy for the Metropolis Light Transport Algorithm 

      Kelemen, Csaba; Szirmay-Kalos, Laszlo; Antal, Gyorgy; Csonka, Ferenc (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      This paper presents a new mutation strategy for the Metropolis light transport algorithm, which works in the unit cube of pseudo-random numbers instead of mutating in the path space. This transformation makes the integrand ...

    • A Skeleton-based Approach for Detection of Perceptually Salient Features on Polygonal Surfaces 

      Hisada, Masayuki; Belyaev, Alexander G.; Kunii, Tosiyasu L. (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      The paper presents a skeleton-based approach for robust detection of perceptually salient shape features. Given ashape approximated by a polygonal surface, its skeleton is extracted using a three-dimensional Voronoi ...

    • Slow Growing Subdivision (SGS) in Any Dimension: Towards Removing the Curse of Dimensionality 

      Pascucci, V. (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      In recent years subdivision methods have been one of the most successful techniques applied to the multi-resolution representation and visualization of surface meshes. Extension these techniques to the volumetric case would ...

    • A Solid Model Based Virtual Hairy Brush 

      Xu, Songhua; Tang, Min; Lau, Francis; Pan, Yunhe (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      We present the detailed modeling of the hairy brush used typically in Chinese calligraphy. The complex model, which includes also a model for the ink and the paper, covers the various stages of the brush going through a ...

    • Space-Optimized Texture Maps 

      Balmelli, Laurent; Taubin, Gabriel; Bernardini, Fausto (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      Texture mapping is a common operation to increase the realism of three-dimensional meshes at low cost. We propose a new texture optimization algorithm based on the reduction of the physical space allotted to the texture ...

    • A Spoken Dialogue System for Navigation in Non-Immersive Virtual Environments 

      McNeill, M.D.J.; Sayers, H.; Wilson, S.; Mc Kevitt, P. (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      Navigation is the process by which people control their movement in virtual environments and is a corefunctional requirement for all virtual environment (VE) applications. Users require the ability to move, controllingorientation, ...

    • STRANDS: Interactive Simulation of Thin Solids using Cosserat Models 

      Pai, Dinesh K. (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      Strandsare thin elastic solids that are visually well approximated as smooth curves, and yet possess essential physical behaviors characteristic of solid objects such as twisting. Common examples in computer graphics ...

    • Stylizing Silhouettes at Interactive Rates: From Silhouette Edges to Silhouette Strokes 

      Isenberg, Tobias; Halper, Nick; Strothotte, Thomas (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      A way to create effective stylized line drawings is to draw strokes that start and stop at visible portions along the silhouette of an object to be portrayed. In computer graphics to date, algorithms to extract silhouette ...

    • Surface reconstruction based on a dynamical system? 

      Giesen, Joachim; John, Matthias (Blackwell Publishers, Inc and the Eurographics Association, 2002)
