* @brief translate point attribute data into a blanking field
|

|
|
*
|
||
|
|
*
|
||
|
|
* 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.
