  • 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 ...
  • Tanaka, Toshimitsu; Takahashi, Tokiichiro (Blackwell Science Ltd and the Eurographics Association, 1994)
    We propose the Cross Scanline Buffer which preserves the result of hidden surface removal as performed by the Cross Scanline Algorithm. The Cross Scan Buffer reduces image re-generation time and eliminates aliasing artifacts ...
  • Akeo, Makoto; Hashimoto, Hiroshi; Kobayashi, Taisuke; Shibusawa, Tetsuo (Blackwell Science Ltd and the Eurographics Association, 1994)
    This paper describes the technical features and method of implementation of our designer support system which enables reproducing a three-dimensional shape from an idea sketch speedily and modifying the reproduced shape ...
  • Branco, Vasco; Costa, Antonio; Ferreira, F. Nunes (Blackwell Science Ltd and the Eurographics Association, 1994)
    The creation of a 3D shape using CAD tools, namely solid modelers, is difficult and time-consuming. Therefore, these systems are kept away from the conceptual phases of design, perhaps the most important in any product ...
  • Wu, Jiann-Rong; Ouhyoung, Ming (Blackwell Science Ltd and the Eurographics Association, 1994)
    In this paper we propose a novel prediction method for the head motion using Grey System theory, where a 6D tracker is attached to an HMD on a user s head in virtual reality applications. Our prediction method using Grey ...
  • DUCE, D.A.; DUKE, D.J.; ten HAGEN, P.J.W.; REYNOLDS, G.J. (Blackwell Science Ltd and the Eurographics Association, 1994)
    Many descriptions of multimedia programming systems are starting to appear in the literature, but little work has yet been done on how to formally specify and reason about such systems. This paper is a contribution on the ...
  • Pattanaik, Sumanta N.; Bouatouch, Kadi (Blackwell Science Ltd and the Eurographics Association, 1994)
    Wavelet analysis has been found [1] to be very useful for functional representation and accurate global solution of radiosity. In radiosity we deal with functions in 2D and 4D spaces. Under such conditions, the biggest ...
  • Feda, Martin; Purgathofer, Werner (Blackwell Science Ltd and the Eurographics Association, 1994)
    This paper presents an efficient method for sampling the illumination functions in higher order radiosity algorithms. In such algorithms, the illumination function is not assumed to be constant across each patch, but it ...
  • PAULIN, Mathias; JESSEL, Jean-Pierre (Blackwell Science Ltd and the Eurographics Association, 1994)
    The radiosity method is one of the most popular rendering algorithms. It allows to simulate interreflections of light accurately between surfaces as energy transfers are well designed. However, this algorithm and its ...
  • Slusallek, Philipp; Pflaum, Thomas; Seidel, Hans-Peter (Blackwell Science Ltd and the Eurographics Association, 1994)
    The RenderMan interface has been proposed as a general interface to rendering systems, yet only a few implementations of the interface exist. In this paper we describe the implementation of the RenderMan interface on a ...
  • Day, A.M.; Turner, S.M.; Arnold, D.B. (Blackwell Science Ltd and the Eurographics Association, 1994)
  • Nehlig, Ph. W.; Duce, D. A. (Blackwell Science Ltd and the Eurographics Association, 1994)
    This paper describes an approach to the formal definition of the design primitive introduced in the revision of the ISO/IEC computer graphics standard, GKS. The paper starts with a general description of the design primitive ...
  • Torres, J.C.; Clares, B. (Blackwell Science Ltd and the Eurographics Association, 1994)
    Graphic objects are an abstract mathematical model for graphic systems. The model is an algebraic approach to represent graphic information, which include modelling operations. This formalism require some method to describe ...
  • van Nieuwenhuizen, Peter R.; Kiewiet, Olaf; Bronsvoort, Willem F. (Blackwell Science Ltd and the Eurographics Association, 1994)
    A method is presented to compute a vector representation of an arbitrary line in a bi-level raster image The line may have varying line width and irregular borders. Furthermore, at line crossings and branches the user is ...
