    • Hardware-Based Volumetric Knit-Wear 

      Daubert, Katja; Seidel, Hans-Peter (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      We present a hardware-based, volumetric approach for rendering knit wear at very interactive rates. A single stitch is represented by a volumetric texture with each voxel storing the main direction of the strands of yarn ...

    • Hybrid Geometric - Image Based Rendering 

      Hidalgo, Eduardo; Hubbold, Roger J. (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      We present a Hybrid Geometric-Image Based Rendering (HGIBR) system for displaying very complex geometrical models at interactive frame rates. Our approach replaces distant geometry with a combination of image-based ...

    • 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 ...

    • Improved Scene Reconstruction from Range Images 

      Wang, Jianning; Oliveira, Manuel M. (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      The modeling of real scenes is a complex and challenging task for which the use of laser rangefinders is one of the most promising approaches. Unfortunately, in many situations, it is not possible or practical to guarantee ...

    • Interactive Visualization with Programmable Graphics Hardware 

      Ertl, Thomas (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      One of the main scientific goals of visualization is the development of algorithms and appropriate data models which facilitate interactive visual analysis and direct manipulation of the increasingly large data sets which ...

    • Intrinsic Parameterizations of Surface Meshes 

      Desbrun, Mathieu; Meyer, Mark; Alliez, Pierre (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      Parameterization of discrete surfaces is a fundamental and widely-used operation in graphics, required, for instance, for texture mapping or remeshing. As 3D data becomes more and more detailed, there is an increased need ...

    • 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. ...

    • Metamorphosis of Polyhedral Surfaces using Decomposition 

      Shlafman, Shymon; Tal, Ayellet; Katz, Sagi (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      This paper describes an algorithm for morphing polyhedral surfaces based on their decompositions into patches. The given surfaces need neither be genus-zero nor two-manifolds. We present a new algorithm for decomposing ...

    • Modeling Surperspective Projection of Landscapes for Geographical Guide-Map Generation 

      Takahashi, Shigeo; Ohta, Naoya; Nakamura, Hiroko; Takeshima, Yuriko; Fujishiro, Issei (Blackwell Science Ltd and the Eurographics Association, 2002)
      It is still challenging to generate hand-drawn pictures because they differ from ordinary photographs in that they are often drawn as seen from multiple viewpoints. This paper presents a new approach for modeling such ...

    • Multi-Resolution Rendering of Complex Animated Scenes 

      Wand, M.; Strasser, W. (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      We present a novel multi-resolution point sample rendering algorithm for keyframe animations. The algorithm accepts triangle meshes of arbitrary topology as input which are animated by specifying different sets of vertices ...

    • Object Space EWA Surface Splatting: A Hardware Accelerated Approach to High Quality Point Rendering 

      Ren, Liu; Pfister, Hanspeter; Zwicker, Matthias (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      Elliptical weighted average (EWA) surface splatting is a technique for high quality rendering of point-sampled 3D objects. EWA surface splatting renders water-tight surfaces of complex point models with high quality, ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...
