// .NAME vtkBlankStructuredGrid - translate point attribute data into a blanking field
|
|
|
|
// .SECTION Description
|
|
// vtkBlankStructuredGrid is a filter that sets the blanking field in a
|
|
// vtkStructuredGrid dataset. The blanking field is set by examining a
|
|
// specified point attribute data array (e.g., scalars) and converting
|
|
// values in the data array to either a "1" (visible) or "0" (blanked) value
|
|
// in the blanking array. The values to be blanked are specified by giving
|
|
// a min/max range. All data values in the data array indicated and laying
|
|
// within the range specified (inclusive on both ends) are translated to
|
|
// a "off" blanking value.
