extract a cells or points from a dataset that have values within a set of thresholds.
<p>
<a class="el" href="a00518.html" title="extract a cells or points from a dataset that have values within a set of thresholds...">vtkExtractSelectedThresholds</a> 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 <a class="el" href="a01707.html" title="extracts cells where scalar value in cell satisfies threshold criterion">vtkThreshold</a> 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.<p>
