  • Smith, Shamus P.; Duke, David J. (Blackwell Publishers Ltd and the Eurographics Association, 2000)
    There are many toolkits and development environments that aid the process of constructing virtual environment applications. Many of these development environments encourage customising a virtual environment's design while ...
  • Thomas, Gwenola; Donikian, Stephane (Blackwell Publishers Ltd and the Eurographics Association, 2000)
    In order to populate virtual cities, it is necessary to specify the behaviour of dynamic entities such as pedestrians or car drivers. Since a complete mental model based on vision and image processing cannot be constructed ...
  • Mizuno, S.; Kasaura, T.; Okouchi, T.; Yamamoto, S.; Okada, M.; Toriwaki, J. (Blackwell Publishers Ltd and the Eurographics Association, 2000)
    In this paper, we study a method to synthesize a multicolor virtual woodblock print by using several virtual woodblocks. It consists of two sections: carving and printing, to synthesize a virtual print. In the carving ...
  • Havran, V.; Bittner, J. (Blackwell Publishers Ltd and the Eurographics Association, 2000)
    We describe two new techniques of ray shooting acceleration that exploit the traversal coherence of a spatial hierarchy. The first technique determines a sequence of adjacent leaf-cells of the hierarchy that is pierced by ...

  • Bernardini, Fausto; Klosowski, James T.; El-Sana, Jihad (Blackwell Publishers Ltd and the Eurographics Association, 2000)
    We present a technique for accelerating the rendering of high depth-complexity scenes. In a preprocessing stage, we approximate the input model with a hierarchical data structure and compute simple view-dependent polygonal ...
  • Jimenez, W. F. H.; Esperanca, C.; Oliveira, A. A. F. (Blackwell Publishers Ltd and the Eurographics Association, 2000)
    The number of polygons in realistic architectural models is many more than can be rendered at interactive frame rates. Typically, however, due to occlusion by opaque surfaces (e.g., walls), only small fractions of such ...
  • Andujar, Carlos; Saona-Vazquez, Carlos; Navazo, Isabel; Brunet, Pere (Blackwell Publishers Ltd and the Eurographics Association, 2000)
    Occlusion culling and level-of-detail rendering have become two powerful tools for accelerating the handling of very large models in real-time visualization applications. We present a framework that combines both techniques ...
  • Attene, Marco; Spagnuolo, Michela (Blackwell Publishers Ltd and the Eurographics Association, 2000)
    In this paper an algorithm is proposed that takes as input a generic set of unorganized points, sampled on a real object, and returns a closed interpolating surface. Specifically, this method generates a closed 2-manifold ...
  • Gopi, M.; Krishnan, S.; Silva, C.T. (Blackwell Publishers Ltd and the Eurographics Association, 2000)
    We present a fast, memory efficient algorithm that generates a manifold triangular mesh S passing through a set of unorganized points P R 3. Nothing is assumed about the geometry, topology or presence of boundaries in the ...
  • Deussen, Oliver; Hiller, Stefan; Van Overveld, Cornelius; Strothotte, Thomas (Blackwell Publishers Ltd and the Eurographics Association, 2000)
    We present a method for computer generated pen-and-ink illustrations by the simulation of stippling. In a stipple drawing, dots are used to represent tone and also material of surfaces. We create such drawings by generating ...
  • Kobbelt, Leif P.; Botsch, Mario (Blackwell Publishers Ltd and the Eurographics Association, 2000)
    We present an interactive system for the generation of high quality triangle meshes that allows us to handle hybrid geometry (point clouds, polygons,. . .) as input data. In order to be able to robustly process huge data ...
  • Ashraf, G.; Wong, K. C. (Blackwell Publishers Ltd and the Eurographics Association, 2000)
    The framespace interpolation algorithm abstracts motion sequences as 1D signals, and interpolates between them to create higher dimension signals, with weights drawn from a user specified curve in a bounded region. We ...
  • Tak, Seyoon; Song, Oh-young; Ko, Hyeong-Seok (Blackwell Publishers Ltd and the Eurographics Association, 2000)
    This paper presents a new technique called motion balance filtering, which corrects an unbalanced motion to a balanced one while preserving the original motion characteristics as much as possible. Differently from previous ...
  • Maillot, Jerome (Blackwell Publishers Ltd and the Eurographics Association, 2000)
    Additional realism can be achieved in computer generated images using smooth and increasingly complex deformations. Though significant effort has been spent on improving these deformations, no general method has been ...
  • Froumentin, Max; Labrosse, Frederic; Willis, Philip (Blackwell Publishers Ltd and the Eurographics Association, 2000)
    A method for image analysis, representation and re-synthesis is introduced. Unlike other schemes it is not pixel based but rather represents a picture as vector data, from which an altered version of the original image can ...
  • Alexa, Marc; Muller, Wolfgang (Blackwell Publishers Ltd and the Eurographics Association, 2000)
    In this paper, we present a representation for three-dimensional geometric animation sequences. Different from standard key-frame techniques, this approach is based on the determination of principal animation components ...
  • Bebie, T.; Bieri, H. (Blackwell Publishers Ltd and the Eurographics Association, 2000)
    In this paper we present SoccerMan, a reconstruction system designed to generate animated, virtual 3D views from two synchronous video sequences of a short part of a given soccer game. After the reconstruction process, ...
  • Lao, Zhiqiang; Li, Ling (Blackwell Publishers Ltd and the Eurographics Association, 2000)
    A method based on computer vision technologies is presented to determine the 3-D spatial locations of joints or feature points of a human body from human motion video. The proposed method first applies the geometric ...
  • Jobard, Bruno; Lefer, Wilfrid (Blackwell Publishers Ltd and the Eurographics Association, 2000)
    In recent years the work on vector field visualization has been concentrated on LIC-based methods. In this paper we propose an alternative solution for the visualization of unsteady flow fields. Our approach is based on ...
