  • Meyers, David (Blackwell Science Ltd and the Eurographics Association, 1994)
    This paper describes an efficient method for constructing a tiling between a pair of planar contours. The problem is of interest in a number of domains, including medical imaging, biological research and geological ...
  • Mah, Sang; Calvert, Thomas W.; Havens, William (Blackwell Science Ltd and the Eurographics Association, 1994)
    Behaviour is a reflection of a reasoning process that must deal with constraints imposed by an external environment, internal knowledge and physical structure. This paper proposes a framework for behavioural animation that ...
  • Benest, I. D. (Blackwell Science Ltd and the Eurographics Association, 1994)
    This paper describes a linearised hypermedia system, called the Book Emulator, that generally supports the capture of diagrammatic specifications such as SSADM and electronic circuit diagrams, and the capture of mathematical ...
  • Kurtenbach, G.; Moran, T. P.; Buxton, W. (Blackwell Science Ltd and the Eurographics Association, 1994)
    Drawing a mark can be an efficient command input technique when using a pen-based computer. However, marks are not intrinsically self-explanatory as are other interactive techniques such as buttons and menus. We present ...
  • Ng, C. M.; Bustard, D. W. (Blackwell Science Ltd and the Eurographics Association, 1994)
    The geometric transformation of an image with irregular shapes from a source space to a target space requires a huge number of multiplications and additions for each pixel. Such a through put is impossible to deliver by ...
  • Palamidese, P.; Crise, A. (Blackwell Science Ltd and the Eurographics Association, 1994)
    Building animations is a current practice to study problems in the computational and experimental sciences. There are several classes of applications which generate descriptions of complex phenomena, based on a large variety ...
  • Mikheev, A.; Nozik, M.; Rubinstein, J. (Blackwell Science Ltd and the Eurographics Association, 1994)
    A new algorithm for computing offset curves is proposed. The algorithm is based on the Huygens principle for propagating wave-fronts. It automatically avoids the topological singularities that appear in conventional methods. ...
  • Preston, M.; Hewitt, W. T. (Blackwell Science Ltd and the Eurographics Association, 1994)
    All animation, whether generated by pen or processor, is concerned with the changing behaviour of synthetic actors through time. Computer animation has allowed an animator to regard different actors as functionally equivalent ...
  • Kuzmin, Yevgeniy P. (Blackwell Science Ltd and the Eurographics Association, 1994)
    This article presents an efficient algorithm for ray traversal of uniform and hierarchical spatial structures. Only simple integer and logical operations are used. The problem of error accumulation during ray casting is ...
  • Kui, Liu Yong (Blackwell Science Ltd and the Eurographics Association, 1994)
    An algorithm for drawing anti-aliased straight lines based on Bresenharn sline algorithm is presented in this paper. Only integer calculations are required. Multiplications or divisions are not needed (only simple ...
  • Paterna , F.; Campari, I.; Scopigno, R. (Blackwell Science Ltd and the Eurographics Association, 1994)
    In this paper the design of a visual program editor and its specification using formal grammars are discussed. We consider an environment to specify, analyse and execute visual programs for a Geographical Information System ...
  • Schettini, R. (Blackwell Science Ltd and the Eurographics Association, 1994)
    A method is presented which, given the RGB values of a colour stimulus displayed on a given cathode ray tube (to which a CIE XYZ triple corresponds), makes it possible to find a spectral reflectance function characterizing ...
  • Pla-Garcia, N. (Blackwell Science Ltd and the Eurographics Association, 1994)
    The Face Octrees are a representation scheme which is very suitable to represent both smooth free form surfaces and solids with smooth boundary, as well as, to perform operations among them. However, the Face Octree ...
  • Jones, Mark W.; Chen, Min (Blackwell Science Ltd and the Eurographics Association, 1994)
    This paper presents a new approach to the construction of a surface from a stack of contour slices. Unlike most existing methods, this new approach handles ambiguous conditions consistently without employing an algorithm ...
  • Dobashi, Yoshinori; Kaneda, Kazufumi; Nakashima, Takanobu; Yamashita, Hideo; Nishita, Tomoyuki and Tadamura, Kastumi (Blackwell Science Ltd and the Eurographics Association, 1994)
    It is inevitable for indoor lighting design to render a room lit by natural light, especially for an atelier or an indoor pool where there are many windows. This paper proposes a method for calculating the illuminance due ...
  • Howic, C.T.; Blake, E.H. (Blackwell Science Ltd and the Eurographics Association, 1994)
    A new algorithm, Mesh Propagation, is presented for the generation of isosurfaces from three-dimensional discrete data sets. While producing the same surface mesh as that generated by a corrected Marching Cubes algorithm, ...
  • Sugihara, Kokichi (Blackwell Science Ltd and the Eurographics Association, 1994)
    This paper presents a numerically robust and topologically consistent algorithm for intersecting convex polyhedra. This algorithm is new in the sense that the consistency issue is completely separated from the numerical ...
  • Yoshida, Norimasa; Shiokawa, Masato; Yamaguchi, Fujio (Blackwell Science Ltd and the Eurographics Association, 1994)
    The technique of solid modeling is essential in CAD/CAM applications, and is currently well established. However, problems remain, such as the lack of uniformity in geometric computations and the lack of stability of Boolean ...
  • Strothotte, Thomas; Preim, Bernhard; Raab, Andreas; Schumann, Jutta; Forsey, David R. (Blackwell Science Ltd and the Eurographics Association, 1994)
    Rendering systems generally treat the production of images as an objective process governed by the laws of physics. However, perception and understanding on the part of viewers are subjective processes influenced by a ...
  • Agrawal, Amitabh; Requicha, Aristides A. G. (Blackwell Science Ltd and the Eurographics Association, 1994)
    Geometric modelers are becoming faster and more powerful, but they still suffer from reliability problems because of floating point errors. Previous work in the field of robust geometric modeling tends to be problem specific ...
