#include <itkOctreeNode.h>
A data structure representing a node in an Octree.
OctreeNode is the basic building block of an octree. It is rarely used by itself, and commonly used by the Octree class.
OctreeNodes have two states: 1) They are a Colored node and the m_Branch is a sentinal value indicating the color, or 2) they are a branch node, and m_Branch is a dynamically allocated array of 8 pointers to OctreeNodes. In the second state, the 8 child OctreeNodes are instantiated by the parent node.
