Detailed Description

OctreeNode data structure, 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.

Author:

Hans J. Johnson This class is the basic building block of an octree. It is rarely used by itself, and commonly used by the Octree class.

Parameters:

ChildID

The numerical identifier of the desired child.

Returns:

A value between 0 and 255 to indicate the color of the Disired child.

Precondition:

Must determine that the specified node is colored (Use IsNodeColored() member function. Behavior is undefined when the child is another Octree.
