|
|
* @brief generate points at center of hyper
|
|
* tree grid leaf cell centers.
|
|
*
|
|
*
|
|
* vtkHyperTreeGridCellCenters is a filter that takes as input an hyper
|
|
* tree grid and generates on output points at the center of the leaf
|
|
* cells in the hyper tree grid.
|
|
* These points can be used for placing glyphs (vtkGlyph3D) or labeling
|
|
* (vtkLabeledDataMapper).
|
|
* The cell 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.
