Abstract

The interface of the Graphical Kernel System GKS is examined with respect to the demands of realtime raster graphics. First the computation time for the different transformations is estimated, to show the great gap between the requirements of realtime operations and the capabilities of conventional minicomputers. It is shown, how the GKS interface supports or with some extensions may support the execution of most of the transformations by a special hardware in the raster workstation.
