    • 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 ...

    • METAVIEWS: A Process-Oriented Approach to CAD and Graphics 

      Takala, Tapio (Eurographics Association, 1988)
      A system-theoretic approach to the computer aided design (CAD) process is presented. Dependency network among objects, consisting of design operations - transactions - is formed automatically during design. The derivation ...

    • 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 ...

    • Monte-Carlo Integration Applied to an Illumination Model 

      Bouville, C.; Dubois, J.L.; Marchal, I.; Viaud, M.L. (Eurographics Association, 1988)
      The use of Monte-Carlo integration together with stochastic sampling is very useful for dealing with the scattering phenomena that occur in the propagation and reflection of light. In this paper, these techniques have been ...

    • A New Algorithm for Converting Boundary Representation to Octree 

      Tang, Zesheng; Lu, Shengkai (Eurographics Association, 1988)
      Conversion algorithms between different object representations have become Increasingly important In soIid modeling system. In this paper, an algorithm for converting boundary representation of 3D object to octree structure ...

    • 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 ...

    • Optimal Texture Mapping 

      De Ma, Song; Lin, Hong (Eurographics Association, 1988)
      Texture mapping is one of the most important techniques for highquality image synthesis. It can enhance immensely the visual richness of raster-scan images. We address in this paper the problem of mapping planar texture ...

    • 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 Procedural System for the Definition and Storage of Technical Drawings in Parametric Form 

      Cugini, U.; Folini, F.; Vicini, I. (Eurographics Association, 1988)
      The construction of a truly USER-FRIENDLY CAD system requires the acquisition and management of a tremendous amount of information which cannot be. and must not be. directly requested from the user, but which has to be ...

    • Pseudo Ordering of CSG-Trees 

      Cottingham, Marion S. (Eurographics Association, 1988)
      Using Constructive Solid Geometry (CSG) methods, it is usual for primitive object representations to be stored at the leaf nodes of binary trees. The major part of the work involved in generating an image of the object is ...

    • 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. ...

    • 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 ...

    • Tools for Efficient Photo-Realistic Computer Animation 

      Stößer, Achim; Schmitt, Alfred; Neidecker, Burkhard; Müller, Heinrich; Maus, Thomas; Leister, Wolfgang (Eurographics Association, 1988)
      The goal of the project “Occursus Cum Novo” was to generate a complex photo-realistic animation of nontrivial length in reasonable time at reasonable cost. Photographic realism comprises complex geometric models as well ...

    • 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 ...

    • Using Algebraic Constraints in Interactive Text and Graphics Editing 

      Li, Jiarong (Eurographics Association, 1988)
      In many graphical application areas such as architectural and mechanical design, spatial relationships are vastly used to construct and manipulate complex objects. They are used to describe dependencies between components ...
