    • Dynamic Textures for Image-based Rendering of Fine-Scale 3D Structure and Animation of Non-rigid Motion 

      Cobzas, Dana; Yerex, Keith; Jagersand, Martin (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      The problem of capturing real world scenes and then accurately rendering them is particularly difficult for fine-scale 3D structure. Similarly, it is difficult to capture, model and animate non-rigid motion. We present a ...

    • Automatic Integration of Facade Textures into 3D Building Models with a Projective Geometry Based Line Clustering 

      Lee, Sung Chun; Jung, Soon Ki; Nevatia, Ram (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      Visualization of city scenes is important for many applications including entertainment and urban mission planning. Models covering wide areas can be efficiently constructed from aerial images. However, only roof details ...

    • 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 ...

    • 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 ...

    • 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, ...

    • 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. ...
