    • A Method for Providing Full Interactive Control of the Shape of 3-D Curves and Surfaces 

      Cros, Frederic; Brock, Philip J. (Eurographics Association, 1988)
      This paper presents a new method for providing an interactive local control on 3-D curves and surfaces. The possibility of interacting directly on the vector tangent to the curve at each control point (e.g. changing its ...

    • Efficient Adaptive Subdivision of Bezier Surfaces 

      Clay, Reed D.; Moreton, Henry P. (Eurographics Association, 1988)
      The support of free-form surfaces by modem solid modeling systems has necessitated the development of hardware and algorithms for the interactive display of surface patches. This paper describes an algorithm for the display ...

    • Architectures for Mass Market 3D Displays 

      Winser, Paul; Bonnet, Thierry; Dumont, Dominique; Mathieu, Yves (Eurographics Association, 1988)
      We discuss the specific architecture requirements of real time 3D display systems intended for low cost mass market products of the near future. Vertex transformation and polygon rendering are two processing aspects where ...

    • Fractal Approximation of 2-D Object 

      Levy-Vehel, J.; Gagalowicz, A. (Eurographics Association, 1988)
      We present some new techniques for shape approximation with fractals, using Iterated Function System, a powerful method which allows good control on the resulting fractal. The main point discussed here can be stated as ...

    • Animation of Stochastic Model-Based 3-D Textures 

      Gagalowicz, Andre; Ma, Song D. (Eurographics Association, 1988)
      We have previously shown the validity of a statistical model proposed by us for realistic textures. We have also shown how to use this model to map realistic textures onto a still surface of any shape and extent, maintaining ...

    • Liberation from Rectangles: A Tiling Method for Dynamic Modification of Objects on Raster Displays 

      Slater, Mel; Davison, Allan; Smith, Mark (Eurographics Association, 1988)
      When graphics objects (also called segments) are used on raster display hardware, problems arise because of the mismatch between the high level requirements of object manipulation, and the low level representation from ...

    • Outline Phase Control for Character Rasterization 

      Hersch, R. D. (Eurographics Association, 1988)
      Character rasterization on middle-resolution output devices (screens, laser printers) is one of the most difficult tasks in the domain of resolution-independent raster imaging. Low sampling leads to unacceptable low-quality ...

    • A Simple Spectral Approach to Stochastic Modelling for Natural Objects 

      Anjyo, Ken-ichi (Eurographics Association, 1988)
      Stochastic modeling has been widely used in computer graphics to depict natural objects or phenomena. Various techniques are available, depending on what object is to be represented and what extent of realism to be achieved. ...

    • Free-Form Surfaces Modeling by Evolution Simulation 

      Lienhardt, Pascal (Eurographics Association, 1988)
      We present in this paper a procedural method for modeling free-form, planar surfaces subdivisions, which allows simulating evolutions of such subdivisions. This method is founded on the common principles deduced from ...

    • A Evalution of Some Three-Color Tiling Patterns 

      Alt, Paul; Cordonnier, Vincent (Eurographics Association, 1988)
      Some new technologies for information display use discrete arrays of cells or picture elements. Each cell displays a single color and the colors do not overlap as they do on a CRT screen. Colored cells are distributed on ...

    • Experimenting with a Parallel Ray-Tracing Algorithm on a Hypercube Machine 

      Priol, Thierry; Bouatouch, Kadi (Eurographics Association, 1988)
      A parallel space tracing algorithm is presented. It subdivides the scene into regions. These latter are distributed among the processors of an iPSC hypercube machine designed by Intel company. Each processor subdivides its ...

    • A System for Graphical Interaction on Parametrized Models 

      Van Emmerik , Maarten J.G.M. (Eurographics Association, 1988)
      A system that enables the definition of parametrized solid models by means of graphical interaction is presented. The position, orientation and dimensions of primitive volumes for Constructive Solid Geometry (CSG) are ...

    • An Object-Oriented Approach to Process Monitoring 

      Hütter, Ronald (Eurographics Association, 1988)
      Current and future user interface requirements of process monitoring applications are summarized. An object-oriented approach to meet these requirements is described. A special displayfile structure, the socalled object-oriented ...

    • G1 Smoothing Solid Objects by Bicubic Bezier Patches 

      Liang, Youdong; Ye, Xiuzi; Fang, Shiaofen (Eurographics Association, 1988)
      A general and unified method is presented for generating a wide range of 3D objects by smoothing the vertices and edges of a given polyhedron with arbitrary topology using bicubic Bezier patches. The common solution to the ...

    • A Compositional Semantics for Graphics 

      Pineda, Luis A. (Eurographics Association, 1988)
      In this paper a theory for developing "intelligent" interactive graphic systems is detailed. The Fregean compositionality principle is enunciated for graphical representations. Geometrical symbols and relations receive ...

    • Construction and Animation of a Synthetic Actress 

      Magnenat-Thalmann, N.; Thalmann, D. (Eurographics Association, 1988)
      This paper describes a method for creating and animating a synthetic actress. It emphasizes the methodology used to generate realistic images and motions. In particular, points which are often ignored in the literature are ...

    • Conversion of Boundary Representations to Bintrees 

      Diehl, Rabanus (Eurographics Association, 1988)
      Methods for the conversion from boundary-representations to approximation models (especially the bintree model) are examined. A new algorithm for the conversion to the bintree model is presented. It employs an inheritence ...

    • Using Algebraic Constraints in Interactive Text and Graphics Editing 

      Li, Jiarong (Eurographics Association, 1988)

    • Towards a System for Exploring the Universe of Polyhedral Shapes 

      Colin, Christian (Eurographics Association, 1988)
      It is often easier to model a shape by giving its properties rather than describing it explicitly. Thus, we are interested in methods which allow us to create shapes automatically by only giving a set of properties. We ...

    • A Formal Specification of a Boundary Representation 

      Baumann, Peter (Eurographics Association, 1988)
      Geometric modellers are used in a wide spectrum of applications in computer graphics. As many other applications use the generated internal representation of solids, semantic correctness is of special importance. On the ...
