|
|
* @brief build a label hierarchy for a graph or point set.
|
|
*
|
|
*
|
|
*
|
|
* Every point in the input vtkPoints object is taken to be an
|
|
* anchor point for a label. Statistics on the input points
|
|
* are used to subdivide an octree referencing the points
|
|
* until the points each octree node contains have a variance
|
|
* close to the node size and a limited population (< 100).
