#include <vtkLabelPlacer.h>
This should probably be a mapper unto itself (given that the polydata output could be large and will realistically always be iterated over exactly once before being tossed for the next frame of the render).
In any event, it takes as input one (or more, eventually) vtkLabelHierarchies that represent prioritized lists of labels sorted by their placement in space. As output, it provides vtkPolyData containing only VTK_QUAD cells, each representing a single label from the input. Each quadrilateral has cell data indicating what label in the input it corresponds to (via an array named "LabelId").

Specifications for the placement of the label relative to an anchor point.

Coordinate systems that output dataset may use.
WORLD | Output 3-D world-space coordinates for each label anchor. |
DISPLAY | Output 2-D display coordinates for each label anchor (3 components but only 2 are significant). |
