adds level and leaf fields to a <a class="el" href="a01741.html" title="A rooted tree data structure.">vtkTree</a>
<p>
The filter currently add two arrays to the incoming <a class="el" href="a01741.html" title="A rooted tree data structure.">vtkTree</a> datastructure. 1) "levels" this is the distance from the root of the vertex. Root = 0 and you add 1 for each level down from the root 2) "leaf" this array simply indicates whether the vertex is a leaf or not<p>
