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.

Member Function Documentation

OctreeNode& itk::OctreeNode::GetChild (  const enum LeafIdentifier  ChildID  )

OctreeNode& itk::OctreeNode::GetChild (  const enum LeafIdentifier  ChildID  )  const

Returns the value of the specified Child for for this OctreeNode Author: Hans J. Johnson Parameters: ChildID  The numerical identifier of the desired child. Returns: A pointer to the Disired child. NOTE: This is always an instance of an OctreeNode.

int itk::OctreeNode::GetColor (  void   )  const

Determines the color value of the specified Child for for this OctreeNode Author: Hans J. Johnson 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.

bool itk::OctreeNode::IsNodeColored (  void   )  const

Determines if the child is a leaf node (colored), or a branch node (uncolored) Author: Hans J. Johnson Parameters: ChildID  The numerical identifier of the desired child. Returns: true if it is colored, false if it is not

void itk::OctreeNode::SetBranch (  OctreeNodeBranch *  NewBranch  )

Sets the color value of the specified Child for for this OctreeNode Author: Hans J. Johnson Parameters: ChildID  The numerical identifier of the desired child. NodeColor  The disired color of this node. Postcondition: All children of the specified child are removed, and the child is set to the desired value.

void itk::OctreeNode::SetColor (  int  NodeColor  )

Sets the color value of the specified Child for for this OctreeNode Author: Hans J. Johnson Parameters: ChildID  The numerical identifier of the desired child. NodeColor  The disired color of this node. Postcondition: All children of the specified child are removed, and the child is set to the desired value.
