ABSTRACT:
The generation of rendering order lists, trees or directed graphs is performed as a pre-process for an interactive three-dimensional graphics system. Notional viewing axes are selected and a rendering order list, tree or directed graph is produced for each of these axes. Viewable directions for a particular list, tree or graph are defined as a viewable region and the size of said region is extended to take account of the field of view of the viewer.
