// .NAME vtkCellCenters - generate points at center of cells
|
|
// .SECTION Description
|
|
// vtkCellCenters is a filter that takes as input any dataset 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 cell
|
|
// attributes will be associated with the points on output.
|
|
//
|
|
// .SECTION Caveats
|
|
// 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.
|

|
