Cellular Architectures and Algorithmsfor Image Synthesis
(The Eurographics Association, 1987)The aim of this paper is to provide some refiexions and partial results about cellular architectures for image synthesis and graphics. As some steps of image synthesis involve a long processing time, quite incompatible ... 
Reconstructing Solids from Tomographic Scans The PARCUM II System·
(The Eurographics Association, 1987)The computeraided design of mechanical parts is supported by sophisticated geometric modelers and visualized by highperformance raster graphics systems allowing for a realistic display. The geometric modeler accepts the ... 
A MultiProcessor Workstationwith a LogicEnhanced Distributed Frame Buffer
(The Eurographics Association, 1987)A graphics workstation should offer both a wide variety of 20 and 3D realtime display functions as well as a programmable parallelprocessing capacity for large processing tasks. A system concept is proposed that meets ... 
A Vectorlike Architecture for Raster Graphics
(The Eurographics Association, 1987)Raster graphics, while good at achieving realistic and costeffective image generation, lacks useful (e.g. highlevel) and fast (e.g. almost realtime) interaction facilities. One may try to speed up the entire classical ... 
VLSI Drawing Processor Utilizing Multiple ParallelScanLine Processors
(The Eurographics Association, 1987)In a typical graphics system, a single drawing processor is used to perform pixel level drawing operations, one pixel at a time. A VLSI based drawing processor and image memory controller is presented which takes advantage ... 
PixelPlanes 4: A Summary
(The Eurographics Association, 1987)We describe the current state of the Pixelplanes research project, whose goal is to develop powerful raster graphics systems for the next generation of workstations, The first fullscale prototype has been in regular use ... 
Parallel Subpixel Scanconversion
(The Eurographics Association, 1987)"IntroductionComputer graphics and its subsections image processing, image analysis and image generation are known to be a wide field for the application of parallel architectures. While in image processing and analysis ... 
A Multiple Application Graphics Integrated CircuitMAGIC II
(The Eurographics Association, 1987)This paper describes the design considerations for a polygon graphics geometry processor subsystem. The architecture for a Multiple Application Graphics Integrated Circuit (MAGIC II) is outlined, and low, medium and high ... 
Comparison of Two Floatin~Point Arithmetic Unitsfor a Precomputer in a Graphics System forReal Time Simulation
(The Eurographics Association, 1987)This paper compares two realized concepts of floating point units in a visual system for a traffic simulator. The hardware structure of a Transformation Processor is described, with which a set of 1x4 vectors can be floating ... 
A TwoDimensional Frame Buffer Processor
(The Eurographics Association, 1987)The twodimensional Frame Buffer Processor (FBP) is part of a proposed raster graphics computer architecture. It is a hardwareoriented organisation of a variation of a bitblt engine with a much richer repertoire. In ... 
3D Graphics For Consumer Applications How Realistic Does it Have to Be?
(The Eurographics Association, 1987)The design of graphics Ie's for the consumer market has performance limitations imposed by the need to maintain low cost, and must be driven by consideration of the potential applications. The likely requirements for a ... 
An O(log N) Parallel Time Exact HiddenLineAlgorithm
(The Eurographics Association, 1987)"Parallel algorithms are given for the exact solution of the hiddenline problem. Most of the parallel algorithms proposed for visibility problems in the literature give approximate solutions. and thus cannot yield an upper ... 
Partially Ordered Search Indices in the Organizationof a Fixed Hierarchy
(The Eurographics Association, 1987)"IntroductionThe mapping of even very advanced algorithms directly to hardware does not typically bring good results as these algorithms are originally designed for sequential processing. However, the power of the modern ... 
Ray Tracing Rational BSpline Patches in VLSI
(The Eurographics Association, 1987)Rational Bspline surfaces make it possible to merge the concepts of freeform surfaces and that of surfaces described by rational polynomials especially conic sections. For ray tracing it is crucial to determine the ... 
An Exact Incremental Hidden Surface RemovalAlgorithm
(The Eurographics Association, 1987)This paper describes an incremental Hidden Surface Removal Algorithm (HSRA), developed to be embedded in a new architecture for raster graphics described in [1,7]. The algorithm can be classified as "exact" since it operates ... 
New Algorithms for Computer Graphics
(The Eurographics Association, 1987)"IntroductionThe area of computational geometry deals with the study of algorithms for problems concerning geometric objects like e.g. lines, polygons, circles, etc. in the plane and in higher dimensional space. Since its ...
