The two-dimensional Frame Buffer Processor (FBP) is part of a proposed raster graphics computer architecture. It is a hardware-oriented organisation of a variation of a bitblt engine with a much richer repertoire. In ...

We describe the current state of the Pixel-planes research project, whose goal is to develop powerful raster graphics systems for the next generation of workstations, The first full-scale prototype has been in regular use ...

"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 ...

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 ...

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 ...

The computer-aided design of mechanical parts is supported by sophisticated geometric modelers and visualized by high-performance raster graphics systems allowing for a realistic display. The geometric modeler accepts the ...

Rational B-spline 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 graphics workstation should offer both a wide variety of 20 and 3D realtime display functions as well as a programmable parallel-processing capacity for large processing tasks. A system concept is proposed that meets ...

"Parallel algorithms are given for the exact solution of the hidden-line problem. Most of the parallel algorithms proposed for visibility problems in the literature give approximate solutions. and thus cannot yield an upper ...

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 ...
