    Liang, Rung-Huei; Ouhyoung, Ming (Blackwell Science Ltd and the Eurographics Association, 1995)
    Many ways of communications are used between human and computer, while using gesture is considered to be one of the most natural way in a virtual reality system. Because of its intuitiveness and its capability of helping ...
  • Modeling 3D Curves of Minimal Energy 

    Veltkamp, Remco C.; Wesselink, Wieger (Blackwell Science Ltd and the Eurographics Association, 1995)
    Modeling a curve through minimizing its energy yields an overall smooth curve. A common way to model shape features is to perform the minimization subject to a number of interpolation constraints. This way of modeling is ...
  • A rational model of the surface swept by a curve* 

    Johnstone, John K.; Williams, James P. (Blackwell Science Ltd and the Eurographics Association, 1995)
    This paper shows how to construct a rational Bezier model of a swept surface that interpolates N frames (i.e., N position/orientation pairs) of a fixed rational space curve c(s) and maintains the shape of the curve at all ...
  • Spherical Triangular B-splines with Application to Data Fitting 

    Pfeifle, Ron; Seidel, Hans-Peter (Blackwell Science Ltd and the Eurographics Association, 1995)
    Triangular B-splines surfaces are a tool for representing arbitrary piecewise polynomial surfaces over planar triangulations, while automatically maintaining continuity properties across patch boundaries. Recently, Alfeld ...

    King, Mike (Blackwell Science Ltd and the Eurographics Association, 1995)
    Does the modern commercial Graphical User Interface constrain the developer of graphics applications into certain interaction styles? This paper looks at the Microsoft Windows environment as an example, with particular ...
  • Reasoning About Gestural Interaction 

    Duke, D.J. (Blackwell Science Ltd and the Eurographics Association, 1995)
    Many of the reported developments in the design of virtual spaces or visualisation systems are based on improvements in technology, either physical devices or algorithms for achieving realistic renderings within real-time ...
  • Automatic Reconstruction of Unstructured 3D Data: Combining a Medial Axis and Implicit Surfaces 

    Bittar, Eric; Tsingos, Nicolas; Gascuel, Marie-Paule (Blackwell Science Ltd and the Eurographics Association, 1995)
    This paper presents a new method that combines a medial axis and implicit surfaces in order to reconstruct a 3D solid from an unstructured set of points scattered on the object s surface. The representation produced is ...
  • Fair Surface Reconstruction Using Quadratic Functionals 

    Kolb, Andreas; Pottmann, Helmut; Seidel, Hans-Peter (Blackwell Science Ltd and the Eurographics Association, 1995)
    An algorithm for surface reconstruction from a polyhedron with arbitrary topology consisting of triangular faces is presented. The first variant of the algorithm constructs a curve network consisting of cubic Bezier curves ...
  • Rendering of Surface and Volume Details in Volume Data* 

    CAI, Wenli; CHEN, Tianzhou; SHI, Jiaoying (Blackwell Science Ltd and the Eurographics Association, 1995)
    Aiming at the detail rendering in volume data, a new volume illumination model, called Composed Scattering Model (CSM), is presented. In order to enhance different details in volume data, scattering intensity is decomposed ...
  • Fast Wavelet Based Volume Rendering by Accumulation of Transparent Texture Maps 

    Lippert, L.; Gross, M. H. (Blackwell Science Ltd and the Eurographics Association, 1995)
    In the following paper, a new method for fast and accurate volume intensity and color integration is elaborated, which employs wavelet decompositions and texture mapping. At this point, it comprises and unifies the advantages ...
  • A Graph-Based Approach to Surface Reconstruction 

    Mencl, Robert (Blackwell Science Ltd and the Eurographics Association, 1995)
    A new approach to the reconstruction of a surface from an unorganized set of points in space is presented. The point set may for example be obtained with a laser scanner or a manual digitizing tool, and is the only source ...
  • Filtering, Clustering and Hierarchy Construction: a New Solution for Ray-Tracing Complex Scenes 

    Cazals, Frederic; Drettakis, George; Puech, Claude (Blackwell Science Ltd and the Eurographics Association, 1995)
    Data structures that handle very complex scenes (hundreds of thousands of objects) have in the past either been laboriously built by hand, or have required the determination of unintuitive parameter values by the user. It ...
  • Discrete Ray-Tracing of Huge Voxel Spaces 

    Stolte, Nilo; Caubet, Rene (Blackwell Science Ltd and the Eurographics Association, 1995)
    The quality of images produced by Discrete Ray-Tracing voxel spaces is highly dependent on 3d grid resolution. The huge amount of memory needed to store such grids often discards discrete Ray-Tracing as a practical ...
  • Synthesizing Feather Textures in Galliformes 

    Dai, Wen-Kai; Shih, Zen-Chung; Chang, Ruei-Chuan (Blackwell Science Ltd and the Eurographics Association, 1995)
    The texture of feather is one of the most fascinating, complicated, and beautiful texture patterns in nature. In this paper, we propose a new and effective texture generation approach that uses the traits of iteration ...
  • Generating a Texture Map from Object-Surface Texture Data 

    Maruya, Makoto (Blackwell Science Ltd and the Eurographics Association, 1995)
    A number of 3D digitizing methods, including stereopsis, are capable of measuring not only an object s shape but also its surface texture. Measured shape data can be expressed as a polyhedron whose faces are triangular, ...
  • Realizing 3D Visual Programming Environments within a Virtual Environment 

    Van Reeth, F.; Coninx, K.; De Backer, S.; Flerackers, E. (Blackwell Science Ltd and the Eurographics Association, 1995)
    In the visual programming community, many interesting graphical metaphors have been reported upon for representing computer programs graphically. Most of them have a 2D or 2.5D appearance on the screen in order to reflect ...
