    • A RASTER GRAPHICS APPROACH TO FLOW VISUALIZATION 

      van Wijk, Jarke J. (Eurographics Association, 1990)
      Most techniques for the visualization of fluid dynamics are based on vector graphics. Streamlines or arrows are calculated as vectors, which are converted to pixels for display on raster devices. The techniques described ...

    • RECONSTRUCTION OF A BOUNDARY REPRESENTATION MODEL FROM THREE ORTHOGRAPHIC PROJECTIONS: A GEOMETRICAL APPROACH 

      Müller, A.; Richter, D. (Eurographics Association, 1990)
      A method is presented for creating a boundary representation model from engineering projections. Although the topic of this reconstruction method has been studied for a few years the fundamentals of reconstruction are ...

    • Relaxed Multi-rate Systolic Array Graphics Engine for High Resolution Real-time Computer Graphics 

      Jayasinghe, J.A.K.S.; Herrmann, O.E. (Eurographics Association, 1990)
      Generation of realistic images while supporting faster interaction is a topic in computer graphics research which has drawn considerable attention. Conventional frame buffer has been identified as a major bottle-neck for ...

    • RENDERING MIRAGES AND OTHER ATMOSPHERIC PHENOMENA 

      Berger, Marc; Levit, Nancy; Trout, Terry (Eurographics Association, 1990)
      The past few years have seen some very impressive results in rendering natural phenomena. This paper addresses the problem of how to model and render optical illusions brought about by atmospheric refraction. Refraction ...

    • Shading and Shadowing with Linear Light Sources 

      Poulin, Pierre; Amanatides, John (Eurographics Association, 1990)
      In virtually all rendering systems, linear light sources are modeled with a series of point light sources that require considerable computing resources to produce realistic looking results. A general solution for shading ...

    • A shadow algorithm for CSG 

      Jansen, Frederik W.; van der Zalm, Arno N. T. (Eurographics Association, 1990)
      An algorithm is presented for constructing shadow volumes for CSG objects. For each primitive solid, the algorithm calculates a tree of shadow volumes to model the shadows generated by the shadow-generating parts of the ...

    • Some Possible Applications of CORDIC Processors in Computer Graphics 

      Kocsis, F.; Böhme, J.F. (Eurographics Association, 1990)
      Some application possibilities of an ASIC-type processing element, the CORDIC processor, in computer graphics are discussed. CORDIC-based solutions are derived for some basic computer geometry computations: conversion ...

    • A Stochastic Functional Approach for Terrain Modeling 

      Dong, Jun-Cai; Peng, Qun-Sheng; Liang, You-Dong (Eurographics Association, 1990)
      A new functional modeling approach - -functional modeling, is presented to depict various classes of natural terrain. While this approach possesses the functions of several previous methods, it does not suffer the drawbacks ...

    • THREE-DIMENSIONAL TEXTURING USING LATTICES 

      Lewis, Robert R. (Eurographics Association, 1990)
      This paper describes a way to perform realistic three-dimensional texturing of ray-traced objects with irregular surfaces. Such texturing has teen done in the past with texture mapping, particle systems, or volumetric ...

    • Tightly-Coupled Multiprocessing for a Global Illumination Algorithm 

      Drettakis, George; Fiume, Eugene; Fournier, Alain (Eurographics Association, 1990)
      A prevailing trend in computer graphics is the demand for increasingly realistic global illumination models and algorithms. Despite the fact that the computational power of uniprocessors is increasing, it is clear that ...

    • TRIES: DATA STRUCTURES BASED ON BINARY REPRESENTATION FOR RAY TRACING 

      Thirion, Jean-Philippe (Eurographics Association, 1990)
      Tries are data structures used for multidimensional searching. We introduce an original method to build Tries for a set of convex polyhedra, weshow how Tries can be used for Ray tracing and we compare them with other data ...

    • TRIMO A Workstation-Based Interactive System for the Generation, Manipulation, and Display of Surfaces over Arbitrary Topological Meshes 

      Slusallek, Philipp B.; Seidel, Hans-Peter (Eurographics Association, 1990)
      TRIMO has been designed as a workstation-based interactive system for the generation, manipulation, and display of surfaces over arbitrary toplogical meshes. In addition to rational tensor product Bezier and B-spline ...

    • WSE: An Environment for Exploring Window Strategies 

      Koivunen, Marja-Riitta (Eurographics Association, 1990)
      This paper describes Window Strategies Environment (WSE), which is an environment for exploring different window strategies. It is a tool for developers who want to implement and explore different window strategies easily. ...
