Display Architecture for VLSI based Graphics Workstations
(The Eurographics Association, 1986)At present, two popular development areas in computer graphics are improvement ofinteraction behaviour and more realistic graphics.The architecture for a high quality interactive workstation proposed in this work isdesigned ... 
"Position Paper:Display Hardware for Boolean Expression Models"
(The Eurographics Association, 1986)In any discussion of graphics hardware there appear to be two basic positions which can be adopted. The first is that of the technologist, who is primarily concerned with what it is possible to make and how to make it. The ... 
Looking at Workstation Architectures from the Viewpoint of Interaction
(The Eurographics Association, 1986)Today's design of sophisticated graphics workstations may be characterized by the terms 3Dsystem, user driven, objectoriented user interfaceand multiplewindows system with the challenge to create high levelinterfaces ...

CSG Hidden Surface Algorithms for VLSI Hardware Systems
(The Eurographics Association, 1986)Constructive Solid Geometry (CSG) is a solid modeling representation thatdefines objects ·as Boolean combinations of primitive solids. For thedisplay of such objects, both the visibility problem and the problem ofcombining ... 
A Visual System for a Traffic Simulator
(The Eurographics Association, 1986)The prototype of a modular CGIsystem for real time simulation in atraffic simulator will be presented. It will be shown, that withthe proposed configuration of a large asymmetric multiprocessorsystem, organized in different ... 
AVLSI Chip for Ray Tracing Bicubic Patches
(The Eurographics Association, 1986)A VLSI chip for ray tracing bicubic patches in Bezier form is explored. The purpose of the chip is to calculate the intersection point of a ray with the bicubic patch to a specified level of accuracy, returning the location ... 
Utilization of VLSI for Creating an Active Data Base of 3D Geometric Models
(The Eurographics Association, 1986)Parallelism of geometric computation can be achieved by distributing the computation efforts according to essentially three different strategies, based on functional, spatial and structural division, respectively (Mantyla ... 
Towards a 3D Graphics Workstation
(The Eurographics Association, 1986)A voxelmap based architecture which lays the foundations for a 3D graphics workstation,called the CUBE Workstation, is presented. The architecture is centered around a largecubic framebuffer of voxels, operated on by ... 
A Survey of Simulator Requirements
(The Eurographics Association, 1986)Simulators have been developed to train pilots, sailors or car drivers withoutthe costs and risks of moving their real vehicles. To obtain high success intraining, the simulators have to provide a high level of realism. ... 
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 ... 
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 ... 
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 ... 
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 ... 
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 ... 
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 ...
