    • Image-Swept Volumes 

      Winter, Andrew S.; Chen, Min (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      Many graphical objects can be represented by swept volumes (including its subset - generalised cylinders) by sweeping 2D or 3D templates along 3D trajectories. In this paper, we present a new approach for constructing swept ...

    • 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 ...

    • 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 ...

    • 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 ...

    • Texture Particles 

      Dischler, J.-M.; Maritaud, K.; Levy, B.; Ghazanfarpour, D. (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      This paper presents an analytical extension of texture synthesis techniques based on the distribution of elementary texture components. Our approach is similar to the bombing, cellular, macrostructured and lapped textures ...

    • Projective Texture Mapping with Full Panorama 

      Kim, Dongho; Hahn, James K. (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      Projective texture mapping is used to project a texture map onto scene geometry. It has been used in many applications, since it eliminates the assignment of fixed texture coordinates and provides a good method of representing ...

    • Angle-Analyzer: A Triangle-Quad Mesh Codec 

      Lee, Haeyoung; Alliez, Pierre; Desbrun, Mathieu (Blackwell Publishers, Inc and the Eurographics Association, 2002)

    • A Frequency-Domain Approach to Watermarking 3D Shapes 

      Ohbuchi, 1 Ryutarou; Mukaiyama, 1 Akio; Takahashi, 2 Shigeo (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      This paper presents a robust watermarking algorithm with informed detection for 3D polygonal meshes. The algorithm is based on our previous algorithm [22] that employs mesh-spectral analysis to modify mesh shapes in their ...

    • Surface reconstruction based on a dynamical system? 

      Giesen, Joachim; John, Matthias (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      We present an efficient algorithm that computes a manifold triangular mesh from a set of unorganized sample points in. The algorithm builds on the observation made by several researchers that the Gabriel graph of the sample ...

    • Using Perceptual Texture Masking for Efficient Image Synthesis 

      Walter, Bruce; Pattanaik, Sumanta N.; Greenberg, Donald P. (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      Texture mapping has become indispensable in image synthesis as an inexpensive source of rich visual detail. Less obvious, but just as useful, is its ability to mask image errors due to inaccuracies in geometry or lighting. ...

    • Efficient Fitting and Rendering of Large Scattered Data Sets Using Subdivision Surfaces 

      Scheib, Vincent; Haber, Jorg; Lin, Ming C.; Seidel, Hans-Peter (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      We present a method to efficiently construct and render a smooth surface for approximation of large functional scattered data. Using a subdivision surface framework and techniques from terrain rendering, the resulting ...

    • 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 ...

    • Local Physical Models for Interactive Character Animation 

      Oore, Sageev; Terzopoulos, Demetri; Hinton, Geoffrey (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      Our goal is to design and build a tool for the creation of expressive character animation. Virtual puppetry, also known as performance animation, is a technique in which the user interactively controls a character's motion. ...

    • 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 ...

    • Transparency in Interactive Technical Illustrations 

      Diepstraten, J.; Weiskopf, D.; Ertl, T. (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      This paper describes how technical illustrations containing opaque and non-opaque objects can be automatically generated. Traditional methods to show transparency in manual drawings are evaluated to extract a small and ...

    • Geometric Approximations Towards Free Specular Comic Shading 

      Winnemoller, Holger; Bangay, Shaun (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      We extend the standard solution to comic rendering with a comic-style specular component. To minimise the computational overhead associated with this extension, we introduce two optimising approximations; the perspective ...

    • Virtual Visual Servoing: a framework for real-time augmented reality 

      Marchand, Eric; Chaumette, Francois (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      This paper presents a framework to achieve real-time augmented reality applications. We propose a framework based on the visual servoing approach well known in robotics. We consider pose or viewpoint computation as a similar ...
