|
|
* @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.
