    QUADTREE SCAN CONVERSION
    (The Eurographics Association, 1984) Oliver, M.A.; King, T.R.; Wiseman, N.E.; K. BO and H.A. TUCKER
    An efficient method is described for turning a quadtree encoding of an image into scan lines. When implemented in hardware it becomes possible to generate video in real time for a raster display without the need for a conventional frame buffer. This suggests that a new form of display processor could be constructed that operates on coded images instead of rasters and (from previous work) that useful speed improvements might then obtain for certain operations.

    TWO DISPLAY ALGORITHMS FOR OCTTREES
    (The Eurographics Association, 1984) Oliver, M.A.; K. BO and H.A. TUCKER
    This paper deals with the problem of the fast display of a three dimensional object that is represented by an Octtree with the Octtree encoded as a simple linear structure without pointers. Two algorithms are described: the first allows a plane section through an Octtree image to be displayed and the second is for the orthographic projection of an Octtree. In the latter algorithm only trivial modifications are needed in order to depth cue. In both algorithms the display image is generated in the form of a quadtree.
