The side, or edge-on view shows how the elevation maps are used to
modify what would otherwise be a single flat quadrilateral. The
offset maps prove effective in extending the useful range of
interactive transformations - before the visual fidelity of the
IBR assisted volume rendering begins to degrade. The nominal
range of motion is confined to a cone with a 32-degree apex,
as claimed by Crawfis et. al. in the original IBRAVR paper.
