Threshold cells within multiple intervals.
This filter can be substituted for a chain of several vtkThreshold filters and can also perform more sophisticated subsetting operations. It generates a vtkMultiBlockDataSet as its output. This multiblock dataset contains a vtkUnstructuredGrid for each thresholded subset you request. A thresholded subset can be a set defined by an interval over a point or cell attribute of the mesh; these subsets are called IntervalSets. A thresholded subset can also be a boolean combination of one or more IntervalSets; these subsets are called BooleanSets. BooleanSets allow complex logic since their output can depend on multiple intervals over multiple variables defined on the input mesh. This is useful because it eliminates the need for thresholding several times and then appending the results, as can be required with vtkThreshold when one wants to remove some range of values (e.g., a notch filter). Cells are not repeated when they belong to more than one interval unless those intervals have different output grids.
Another advantage this filter provides over vtkThreshold is the ability to threshold on non-scalar (i.e., vector, tensor, etc.) attributes without first computing an array containing some norm of the desired attribute. vtkMultiThreshold provides , , and norms.
This filter makes a distinction between intermediate subsets and subsets that will be output to a grid. Each intermediate subset you create with AddIntervalSet or AddBooleanSet is given a unique integer identifier (via the return values of these member functions). If you wish for a given set to be output, you must call OutputSet and pass it one of these identifiers. The return of OutputSet is the integer index of the output set in the multiblock dataset created by this filter.
For example, if an input mesh defined three attributes T, P, and s, one might wish to find cells that satisfy "T < 320 [K] && ( P > 101 [kPa] || s < 0.1 [kJ/kg/K] )". To accomplish this with a vtkMultiThreshold filter,
vtkMultiThreshold* thr; int intervalSets[3]; intervalSets[0] = thr->AddIntervalSet( vtkMath::NegInf(), 320., vtkMultiThreshold::CLOSED, vtkMultiThreshold::OPEN, vtkDataObject::FIELD_ASSOCIATION_POINTS, "T", 0, 1 ); intervalSets[1] = thr->AddIntervalSet( 101., vtkMath::Inf(), vtkMultiThreshold::OPEN, vtkMultiThreshold::CLOSED, vtkDataObject::FIELD_ASSOCIATION_CELLS, "P", 0, 1 ); intervalSets[2] = thr->AddIntervalSet( vtkMath::NegInf(), 0.1, vtkMultiThreshold::CLOSED, vtkMultiThreshold::OPEN, vtkDataObject::FIELD_ASSOCIATION_POINTS, "s", 0, 1 ); int intermediate = thr->AddBooleanSet( vtkMultiThreshold::OR, 2, &intervalSets[1] ); int intersection[2]; intersection[0] = intervalSets[0]; intersection[1] = intermediate; int outputSet = thr->AddBooleanSet( vtkMultiThreshold::AND, 2, intersection ); int outputGridIndex = thr->OutputSet( outputSet ); thr->Update();
The result of this filter will be a multiblock dataset that contains a single child with the desired cells. If we had also called thr->OutputSet( intervalSets[0] );
, there would be two child meshes and one would contain all cells with T < 320 [K]. In that case, the output can be represented by this graph
The filled rectangles represent sets that are output.

When an interval is evaluated, its value is used to update a truth table.
If its value allows the output of the truth table to be determined, then either INCLUDE or EXCLUDE is returned. Otherwise, INCONCLUSIVE is returned and more intervals must be evaluated.
As an example, consider the ruleset {A>10} & ( {6<B<8} | {C==12} ). We first evaluate A. Say A is 100. This makes the first rule true, but the value of the rule set is still indeterminate. INCONCLUSIVE is returned. Next we consider B. If B is 7, then INCLUDE will be returned and there is no need to examine C. If B is 0, then INCONCLUSIVE is returned again and we must examine C. If C is 12, then INCLUDE is returned, otherwise EXCLUDE is returned.

Add a mesh subset to be computed by thresholding an attribute of the input mesh.
The subset can then be added to an output mesh with OutputSet() or combined with other sets using AddBooleanSet. If you wish to include all cells with values below some number a, call with xmin set to vtkMath::NegInf() and xmax set to a. Similarly, if you wish to include all cells with values above some number a, call with xmin set to a and xmax set to vtkMath::Inf(). When specifying Inf() or NegInf() for an endpoint, it does not matter whether you specify and open or closed endpoint.
When creating intervals, any integers can be used for the IDs of output meshes. All that matters is that the same ID be used if intervals should output to the same mesh. The outputs are ordered with ascending IDs in output block 0.
It is possible to specify an invalid interval, in which case these routines will return -1. Invalid intervals occur when

These convenience members make it easy to insert closed intervals.
The "notch" interval is accomplished by creating a bandpass interval and applying a NAND operation. In this case, the set ID returned in the NAND operation set ID. Note that you can pass xmin == xmax when creating a bandpass threshold to retrieve elements matching exactly one value (since the intervals created by these routines are closed).
