contains an octree of labels
<p>
This class represents labels in a hierarchy used to denote rendering priority. A binary tree of labels is maintained that subdivides the bounds of the of the label anchors spatially. Which level of the tree a label occupies determines its priority; those at higher levels of the tree will be more likely to render than those at lower levels of the tree.<p>
Pass <a class="el" href="a00940.html" title="contains an octree of labels">vtkLabelHierarchy</a> objects to a <a class="el" href="a00946.html" title="place a prioritized hierarchy of labels in screen space">vtkLabelPlacer</a> filter for dynamic, non-overlapping, per-frame placement of labels.<p>
Note that if we have a d-dimensional binary tree and we want a fixed number <img class="formulaInl" alt="$n$" src="form_66.png"> of labels in each node (all nodes, not just leaves), we can compute the depth of tree required assuming a uniform distribution of points. Given a total of <img class="formulaInl" alt="$N$" src="form_67.png"> points we know that <img class="formulaInl" alt="$\frac{N}{|T|} = n$" src="form_68.png">, where <img class="formulaInl" alt="$|T|$" src="form_69.png"> is the cardinality of the tree (i.e., the number of nodes it contains). Because we have a uniform distribution, the tree will be uniformly subdivided and thus <img class="formulaInl" alt="$|T| = 1 + 2^d + \left(2^d\right)^2 + \cdots + \left(2^d\right)^k$" src="form_70.png">, where <img class="formulaInl" alt="$d$" src="form_71.png"> is the dimensionality of the input points (fixed at 3 for now). As <img class="formulaInl" alt="$k$" src="form_72.png"> becomes large, <img class="formulaInl" alt="$|T|\approx 2 \left(2^d\right)^k$" src="form_73.png">. Using this approximation, we can solve for <img class="formulaInl" alt="$k$" src="form_72.png">: <p class="formulaDsp">
<img class="formulaDsp" alt="\[ k = \frac{\log{\frac{N}{2n}}}{\log{2^d}} \]" src="form_74.png">
<p>
Given a set of <img class="formulaInl" alt="$N$" src="form_67.png"> input label anchors, we'll compute <img class="formulaInl" alt="$k$" src="form_72.png"> and then bin the anchors into tree nodes at level <img class="formulaInl" alt="$k$" src="form_72.png"> of the tree. After this, all the nodes will be in the leaves of the tree and those leaves will be at the <img class="formulaInl" alt="$k$" src="form_72.png">-th level; no anchors will be in levels <img class="formulaInl" alt="$1, 2, \ldots, k-1$" src="form_75.png">. To fix that, we'll choose to move some anchors upwards. The exact number to move upwards depends on <em>TargetLabelCount</em>. We'll move as many up as required to have <em>TargetLabelCount</em> at each node.<p>
You should avoid situations where <em>MaximumDepth</em> does not allow for <em>TargetLabelCount</em> or fewer entries at each node. The <em>MaximumDepth</em> is a hard limit while <em>TargetLabelCount</em> is a suggested optimum. You will end up with many more than <em>TargetLabelCount</em> entries per node and things will be sloooow.<p>
