Fig. 6: Fully vs. partially mapped octree nodes.

Blue bricks in the page table (right) are resident in the cache. Dashed lines indicate that a node from the residency octree is partially mapped, and solid lines indicate that a node is fully mapped. The cross-hatched node in the octree (left) is fully mapped in all resolution levels, l0, l1, and l2, in the page table (right). The single-hatched node is partially mapped in l0, and fully mapped in l2. Note that l0, l1, and l2 cover the same spatial extent.
