Abstract

This contribution describes some work being undertaken in the design andimplementation of architectures for high performance Computer Image Generationfor a range of applications from workstations to flight simulator visual systems.The work to be described uses a model based on a polygon representation anduses a Geometry Processor sub-system, with a flexible architecture known asMAGIC. This system performs the transformation of the polygon from the 3-Drepresentation to the 2-D perspective projection to the viewing screenco-ordinates and also provides a clipping operation optional in 3-D or 2-D.Two different types of scan conversion system are described, the first the ZoneManagement Processor uses the coherence inherent in the polygon and thesecond system based on a Line Processor uses coherence with spans.
