A Display Controller for an Object-level Frame Store System

In [3] and [1] a new architecture for a Computer Image Generating (CIG) system designed to have optimal Interaction support for realistlc 3D graphics has been presented. There it was stated that -- from an interaction point of viewthere is no need to have access to an image representation as low as the pixel level. This and the fact that the performance and resolution to a major extend has been limited by the pixel update speed enforced by memory technologies. led us to the conclusion that it should be investigated whether a CRT display could be refreshed from an object-level representation of the frame instead of the conventional pixel-level frame store. In this paper we present as a result of this study an architecture of a (multi-processor) Display Controller that is capable to directly refresh a raster display from such an object-level frame representation.
