    A Virtual Memory System Organization for Bit-Mapped Graphics Displays
    (The Eurographics Association, 1989) Barkans, Anthony C.; Richard Grimsdale and Wolfgang Strasser
    Described is a display sub-system, designed for support of a very high speed rendering engine. It provides high-performance graphics to an enVironment that consists of a hierarchy of resizable windows. The concept of virtual memory has been applied with the organization of the virtual to physical address spaces having a unique mapping that fits the organization of a bit-mapped graphics memory display.

    Point-driven Generation of Images from a Hierarchical Data Structure
    (The Eurographics Association, 1988) Jong, Dirk de; Siobbe, Paul van; Splunter, Marinus van; A. A. M.Kuijk
    In this paper, a system IS described which renders an image from a hierarchical data structure in a point-driven way. The data structure allows dynamic color mapping and arbitrary affine transformat·ons of objects with respect to their parent coordinate system. The point driven method allows for easy VLSI implementation, efficient use oj memory and exploitation of parallelism.
