* @class vtkValueSelector
|
|
* @brief selects elements matching chosen values.
|
|
*
|
|
* vtkValueSelector is a vtkSelector that can select elements matching
|
|
* values. This can handle a wide array of vtkSelectionNode::SelectionContent types.
|
|
* These include vtkSelectionNode::GLOBALIDS, vtkSelectionNode::PEDIGREEIDS,
|
|
* vtkSelectionNode::VALUES, vtkSelectionNode::INDICES, and
|
|
* vtkSelectionNode::THRESHOLDS.
|
|
*
|
|
* A few things to note:
|
|
*
|
|
* * vtkSelectionNode::SelectionList must be 2-component array for
|
|
* content-type = vtkSelectionNode::THRESHOLDS and 1-component array for all
|
|
* other support content-types. For 1-component selection list, this will
|
|
* match items where the field array (or index) value matches any value in the
|
|
* selection list. For 2-component selection list, this will match those items
|
|
* with values in inclusive-range specified by the two components.
|
|
*
|
|
* * For vtkSelectionNode::VALUES or vtkSelectionNode::THRESHOLDS, the field
|
|
* array to select on is defined by the name given the SelectionList itself.
|
|
* If the SelectionList has no name (or is an empty string), then the active
|
|
* scalars from the dataset will be chosen.
