Fig. 9: Number of bricks required to be resident in the cache per pixel.

Brighter pixels indicate more bricks. (a) Page table hierarchies have limited empty-space skipping capabilities and can access bricks that potentially contain many values outside the currently visible value range. (b) Octrees require lower resolutions in the cache in order to render higher resolutions. (c) Residency octrees do not have either of these limitations, only requiring bricks that are visible under the current viewing conditions to be in the cache, allowing for larger working sets and/or less cache thrashing.
