      Weißmann, Steffen (Weißmann, 15. 9. 201)
      This cumulative dissertation presents a complete model for simulating smoke usingpolygonal vortex filaments. Based on a Hamiltonian system for the dynamics ofsmooth vortex filaments, we develop an effcient and robust ...
    • Schnelle Kurven- und Flächendarstellung auf grafischen Sichtgeräten 

      Straßer, Wolfgang (1974-09-05)
      Für die Anwendung beim interaktiven Entwurf von Kurven und Flächen auf grafischen Sichtgeräten werden im ersten Teil der Arbeit bekannte mathematische Verfahren in einer kompakten, einheitlichen Matrizenschreibweise ...
    • COMPUTER GRAPHICS IN MULTIPLE MICROPROCESSOR SYSTEM 

      Ae, Tadashi; Takahashi, Koichi; Chiba, Haruyoshi; Ito, Tsurumi (The Eurographics Association, 1980)
      In this paper we propose a method to implement the moving patterns which are consecutively related in a small computer system. Suppose that the patterns are constructed of many block elements. A pattern is derived by the ...
    • Easy to Use Graph Drawing Procedures in ALGOL 68 

      Butland, S. D.; Butland, J. (The Eurographics Association, 1980)
      An ALGOL68 implementation of a comprehensive set of graph drawing procedures is described. The procedures are designed to enable scientists and engineers writing programs in ALGOL68 to produce a wide range of graphs with ...
    • THE DESIGN OF A GENERAL-PURPOSE COMMAND INTERPRETER FOR GRAPHICAL MAN-MACHINE COMMUNICATION TO BE BUILT ON TOP OF A GKS 

      Borufka, H.G.; Pfaff, G. (The Eurographics Association, 1980)
      A model of a general purpose graphical command interpreter (KI) is presented. It is based on the graphical kernel system (GKS) and provides the user with the most common set of commands for solving graphical problems in a ...
    • SGL - A GENERAL PURPOSE INTERACTIVE SYSTEM BUILT ON TOP OF A GKS IMPLEMENTATION 

      Cunha, J.D. (The Eurographics Association, 1980)
      This paper presents the description of an interactive graphics system built on top of a GKS level 4 implementation. The system architecture is based on the notion of Process and the mainemphasis has been devoted to design ...
    • TRIAL-AND-ERROR APPLICATIONS FOR INTERACTIVE DATA REPRESENTATION 

      Vincents, Bo (The Eurographics Association, 1980)
      This paper examines the advantages available to planners and experimental theorists of using computers to visualise their theories by generating a multiplicity of graphs interactively. The paper focuses on statistical ...
    • CONSIDERATIONS ON EXTENSIONS OF INPUT FUNCTIONS BASED ON A GRAPHICAL KERNEL SYSTEM 

      Hillebrand, K.; Weiss, J. (The Eurographics Association, 1980)
      The German DIN-Proposal for Graphic Systems provides five classes of input types and three different methods of reading them. In this paper considerations are made on providing a much more powerful interface for the ...
    • SURFACE FITTING BY MEANS OF SPLINES 

      Brunet, P. (The Eurographics Association, 1980)
      Algoritms related with surface interpolation use either global interpolants or local methods. When dealing with irregularly distributed data points, the former are usually cumbersome whereas the later may present continuity ...
