Snaps points at the center of a cell.
vtkCellCentersPointPlacer is a class to snap points on the center of cells. The class has 3 modes. In the ParametricCenter mode, it snaps points to the parametric center of the cell (see vtkCell). In CellPointsMean mode, points are snapped to the mean of the points in the cell. In 'None' mode, no snapping is performed. The computed world position is the picked position within the cell.
- Usage:
- The actors that render data and wish to be considered for placement by this placer are added to the list as
placer->AddProp( actor );

- vtkPointPlacer
- Tests:
- vtkCellCentersPointPlacer (Tests)
