// .NAME vtkIdFilter - generate scalars or field data from point and cell ids
|
|
// .SECTION Description
|
|
// vtkIdFilter is a filter to that generates scalars or field data
|
|
// using cell and point ids. That is, the point attribute data scalars
|
|
// or field data are generated from the point ids, and the cell
|
|
// attribute data scalars or field data are generated from the the
|
|
// cell ids.
|
|
//
|
|
// Typically this filter is used with vtkLabeledDataMapper (and possibly
|
|
// vtkSelectVisiblePoints) to create labels for points and cells, or labels
|
|
// for the point or cell data scalar values.
