extracts cells where scalar value in cell satisfies threshold criterion
<p>
<a class="el" href="a01707.html" title="extracts cells where scalar value in cell satisfies threshold criterion">vtkThreshold</a> is a filter that extracts cells from any dataset type that satisfy a threshold criterion. A cell satisfies the criterion if the scalar value of (every or any) point satisfies the criterion. The criterion can take three forms: 1) greater than a particular value; 2) less than a particular value; or 3) between two values. The output of this filter is an unstructured grid.<p>
Note that scalar values are available from the point and cell attribute data. By default, point data is used to obtain scalars, but you can control this behavior. See the AttributeMode ivar below.<p>
By default only the first scalar value is used in the decision. Use the ComponentMode and SelectedComponent ivars to control this behavior.<p>
