Queries the orthant index for this (leaf's or node's) hyper-cube
with respect to a given outer hyper-cube iq
.
Computes the greatest interesting hyper-cube within
a given hyper-cube mq
so that this (leaf's or node's)
hyper-cube and the given point will be placed in
separated orthants of this resulting hyper-cube.
A leaf in the octree, carrying a map entry in the form of a point and associated value. Note that a single instance of a leaf is used across the levels of the octree! That means that multiple child pointers may go to the same leaf, while the parent of a leaf always points into the highest level octree that the leaf resides in, according to the skiplist.
