Detailed Description

Places and renders non-overlapping labels.

To use this mapper, first send your data through vtkPointSetToLabelHierarchy, which takes a set of points, associates special arrays to the points (label, priority, etc.), and produces a prioritized spatial tree of labels.

This mapper then takes that hierarchy (or hierarchies) as input, and every frame will decide which labels and/or icons to place in order of priority, and will render only those labels/icons. A label render strategy is used to render the labels, and can use e.g. FreeType or Qt for rendering.
