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.10.2312/eg.19841019
