/**
* @class vtkEdgeCenters
* @brief generate points at center of edges
*
* vtkEdgeCenters is a filter that takes as input any graph and
* generates on output points at the center of the cells in the dataset.
* These points can be used for placing glyphs (vtkGlyph3D) or labeling
* (vtkLabeledDataMapper). (The center is the parametric center of the
* cell, not necessarily the geometric or bounding box center.) The edge
* attributes will be associated with the points on output.
*
* @warning
* You can choose to generate just points or points and vertex cells.
* Vertex cells are drawn during rendering; points are not. Use the ivar
* VertexCells to generate cells.
*
* @sa
* vtkGlyph3D vtkLabeledDataMapper
