  • Arinyo, Robert Juan (Blackwell Science Ltd and the Eurographics Association, 1995)
    We consider the problem of converting boundary representations of isothetic polyhedra into constructive solid geometry (CSG) representations. The CSG representation is a boolean formula based on the half-spaces supporting ...
  • Kuzmin, Yevgeny P. (Blackwell Science Ltd and the Eurographics Association, 1995)
    One of the most important operations in many graphical systems is the generation of a line segment. This process consists of two stages: clipping and drawing. These two stages are separated in current graphical applications. ...
  • Logie, J. R.; Patterson, J. W. (Blackwell Science Ltd and the Eurographics Association, 1995)
    Inverse Displacement Mapping is a form of displacement mapping which allows the ray tracing of displacement mapped surfaces. The technique performs all calculations in the inverse (parametric) space of the surface thus ...
  • Lau, Wing Hung; Wiseman, Neil (Blackwell Science Ltd and the Eurographics Association, 1995)
    In this paper, we describe a new buffer architecture called the Compositing Buffer. Although it is based on the A-buffer architecture described by Carpenter1, the new architecture introduces two important ideas which make ...
  • Dischler, Jean-Michel; Ghazanfarpour, Djamchid (Blackwell Science Ltd and the Eurographics Association, 1995)
    Conventional 2D or 3D texturing methods do not permit an efficient simulation of highly complex structured textures like fire, fur, cotton, etc. More recent techniques, using specific kinds of 3D textures, such as hypertextures ...
  • Morer, Paz; Alonso, Alejandro M. Garcia; Flaquer, Juan (Blackwell Science Ltd and the Eurographics Association, 1995)
    Architectural scenes usually have some peculiar properties, like parallel surfaces, symmetry, instantiation, easy clustering, etc. These properties can be used by visualization algorithms in order to improve the solution ...
  • Keates, M.J.; Hubbold, R.J. (Blackwell Science Ltd and the Eurographics Association, 1995)
    This paper describes the results of experiments with accelerated ray tracing on a virtual shared-memory parallel computer and attempts to determine whether this kind of architecture would be suitable for an interactive ray ...
  • Savchenko, Vladimir V.; Pasko, Alexander A.; Okunev, Oleg G.; Kunii, Tosiyasu L. (Blackwell Science Ltd and the Eurographics Association, 1995)
    This paper presents a novel approach to the reconstruction of geometric models and surfaces from given sets of points using volume splines. It results in the representation of a solid by the inequality f(x,y,z) ? 0. The ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
