* @class vtkExtractSelectedThresholds
|
|
* @brief extract a cells or points from a
|
|
* dataset that have values within a set of thresholds.
|
|
*
|
|
*
|
|
* vtkExtractSelectedThresholds extracts all cells and points with attribute
|
|
* values that lie within a vtkSelection's THRESHOLD contents. The selecion
|
|
* can specify to threshold a particular array within either the point or cell
|
|
* attribute data of the input. This is similar to vtkThreshold
|
|
* but allows mutliple thresholds ranges.
|
|
* This filter adds a scalar array called vtkOriginalCellIds that says what
|
|
* input cell produced each output cell. This is an example of a Pedigree ID
|
|
* which helps to trace back results.
