Optimal Texture Mapping
(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 ... -
Monte-Carlo Integration Applied to an Illumination Model
(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 Compositional Semantics for Graphics
(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 ... -

Efficient Adaptive Subdivision of Bezier Surfaces
(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 ... -
Construction and Animation of a Synthetic Actress
(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 ... -
Fast Algorithm for Polygon Clipping with 3D Windows
(Eurographics Association, 1988)Many applications which use 3D graphics, need 3D geometric modeling and hence polygon clipping against 3D Windows or general volumes. The disadvantages of existing clipping algorithms are that they are 2D, slow or produce ... -
Architectures for Mass Market 3D Displays
(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 ... -
IXPHIGS: A Portable Implementation of the International PHIGS Standard
(Eurographics Association, 1988)This paper describes a "portable" object-oriented implementation of the international standard PHIGS. A rapid prototype has been achieved by making use of earlier developments : the IX-CGI module for graphical input, output ... -
Application Profiles for Computer Graphics Standards - A Touch of Realism
(Eurographics Association, 1988)Computer graphics standards have become widely used and are now a fact of life. We have reached the stage of reviewing and extending the current standards. There is an important move within the user community which needs ... -
Fractal Approximation of 2-D Object
(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 ... -
Conversion of Boundary Representations to Bintrees
(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
(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 ... -
Towards a System for Exploring the Universe of Polyhedral Shapes
(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 ... -
Animation of Stochastic Model-Based 3-D Textures
(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
(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 ... -
Pseudo Ordering of CSG-Trees
(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 ... -
Outline Phase Control for Character Rasterization
(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
(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 Formal Specification of a Boundary Representation
(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 ...
