to be rendered, and are not placed into an intermediate output stream that will
not result in any further processing or rendering.
Figures 1.4(a)-1.4(f) show examples of a viewable region after a number of
iterations through our subdivision algorithm.
LOD Transition Algorithm
In Stage 3 of the algorithm, a stream of viewable regions are rendered. One view-
able region R with an applied offset of R λ may be adjacent to another viewable
