Item Dear EUROGRAPHICS Friends!(Blackwell Publishing Ltd and the Eurographics Association, 1985) Encarnacao, JoseItem Displaying Random Fields(Blackwell Publishing Ltd and the Eurographics Association, 1985) Coquillart, SabineThis paper presents an algorithm for random fields generation. The main idea of the paper is an improvement of the recursive technique presented by A. Fournier, D. Fussel and L. Carpenter in [4]. In order to ensure the continuity constraints on the boundaries of the cells generated at different stages of the algorithm, we show that it is possible to store the boundary values using a dynamic data structure. Random fields have been successfully used to model height fields or to display synthetic textures. In the second part of this paper we investigate the perspective mapping and clipping stages of random fields generation and display. At the end of the paper, some synthetic skies displayed using this technique are presented.Item Book Reviews(Blackwell Publishing Ltd and the Eurographics Association, 1985)A Programmer’s Geometry by A.

The system is based on a hierarchical asynchronous multiple microprocessor system. In practice this mini-computer is extendable up to 15-20 workstations. On the workstations, different graphical and non-graphical devices can be connected. The most interesting workstation is a raster graphics display device which was developed specially for the computer system described. This raster graphics display device contains a processor for the application program, two dedicated processors and two separate identical frame buffers, each of them containing one whole set of image data. Applying algorithms for anti-aliasing, virtual pixel dislocation (intensity dislocation) and multi-pixel-overlappings with hidden line (surface) elimination the image readability and quality can be increased considerably. In particular the paper deals with an anti-aliasing algorithm with a real-time hardware realization.Item Eurographics Uk Chapter 4th UK Conference(Blackwell Publishing Ltd and the Eurographics Association, 1985) Kilgour, AlistairItem Report on the MICROGRAPHICS Workshop(Blackwell Publishing Ltd and the Eurographics Association, 1985) Scheller, AngelaItem Report on the CREST Advanced Course on 3D Computer Graphics University of Glasgow, 27th August - 7th September, 1984(Blackwell Publishing Ltd and the Eurographics Association, 1985) Kilgour, AlistairItem The Graphics PARCUM* System: A 3D Memory Based Computer Architecture for Processing and Display of Solid Models(Blackwell Publishing Ltd and the Eurographics Association, 1985) Jackel, D.The concept of a computer architecture for processing and display of spatially ordered data is presented in this paper. The central part of the architecture is a memory cube in which the objects can be processed in their real shape as a three-dimensional data array. The development has been rendered possible at reasonable costs through the rapid progress in the realm of VLSI-memory technology.Item Calendar of Events(Blackwell Publishing Ltd and the Eurographics Association, 1985)Item AFFILIATION AGREEMENT(Blackwell Publishing Ltd and the Eurographics Association, 1985)Item Executive Committee Elections(Blackwell Publishing Ltd and the Eurographics Association, 1985) Duce, DavidItem A Proposal for an ALGOL 68 Binding of GKS(Blackwell Publishing Ltd and the Eurographics Association, 1985) Martin, R.R.; Anderson, C.Item FINANCIAL REPORT(Blackwell Publishing Ltd and the Eurographics Association, 1985)Item Some Issues in Designing User Interfaces to 3D Raster Graphics(Blackwell Publishing Ltd and the Eurographics Association, 1985) van Wijk, J.J.; Jansen, F.W.; Bronsvoort, W.F.Now that raster graphics has become a common tool in CAD/CAM systems, animation and many other applications, the need has arisen for user interfaces to graphics packages for these new applications. On the basis of a typology of the users, an analysis is presented of some of the choices which have to be made in developing these interfaces.Item Seeheim Workshop on User Interface Management Systems Report of the Working Group on the User’s Conceptual Model*(Blackwell Publishing Ltd and the Eurographics Association, 1985) Mac an Airchinnigh, M.Item Dear EUROGRAPHICS Friends!(Blackwell Publishing Ltd and the Eurographics Association, 1985) ten Hagen, PaulItem Raster Graphics(Blackwell Publishing Ltd and the Eurographics Association, 1985) Strasser, WolfgangItem EDITORIAL(Blackwell Publishing Ltd and the Eurographics Association, 1985) Enderle, Gunter; Arnold, David
