A MICROPROGRAMMED DISPLAY PROCESSOR CONCEPT FOR 3-D DYNAMIC INTERACTIVE COMPUTER GRAPHICS by Reiner W. Hartenstein and Klaus D. Mueller Karlsruhe University D-75 Karlsruhe I, F.R.Germany Introduction: In SIGMICRO Newsletter, (graphics) Vol. 3, Nr. i Andries van Dam defined the term "Interactive into the two broad categories "interactive Computer Graphics" plotting" and divided its applications and "interactive design". In this paper, we want to suggest a system, which provides all those "necessary features", intermediate demanded by A. van Dam. Our suggested system is one of the type "powerful which may be used in a "stand alone mode" or a price, microprogrammed graphics", "satellite mode". A survey of the system configuration ral purpose data base), manipulated, and a vector-generator, cooperating is given by Fig. I. Graphical data is separated (out of a gene- and CRT-displayed by means of three special-purpose-processors in a pipeline mode. Data Base: The data base of the system is a hierarchically organized, structure /i/, handled by a package of microprogrammed ring implemented ASP-type "macros". This data structure allows the Interrogative functions representation of any association between arbitrary data substructures. are possible, shortening response-time. For display refreshing, the data base is accessed directly, so that the use
