Extract Selections (ExtractSelections)
Extract different type of selections.
This filter extracts a set of cells/points given a selection.

The selection can be obtained from a rubber-band selection

(either cell, visible or in a frustum) or threshold selection

and passed to the filter or specified by providing an ID list.

PropertyDescriptionDefault Value(s)Restrictions
Input
(Input)
This property specifies the input from which the selection is extracted.  

The selected object must be the result of the following: sources (includes readers), filters.

The selected dataset must be one of the following types (or a subclass of one of them): vtkDataSet.

 
Array Name
(ArrayName)
For threshold and value selection, this controls the name of the scalar array that will be thresholded within. Text  
Containing Cells
(ContainingCells)
When field type is POINT, this controls whether single vertex cells will be produced for each selected point, or whether the cells that contain each selected point will be produced. When field type is CELL this has no effect. 0

Only the values 0 and 1 are accepted.

 
Content Type
(ContentType)
The type of content of the selection generated by the selection source. 5

The value must be one of the following: SELECTIONS (0), COMPOSITE_SELECTIONS (1), GLOBALIDs (2), PEDIGREEIDS (3), VALUES (4), INDICES (5), FRUSTUM (6), LOCATION (7), THRESHOLDS (8).

 
Field Type
(FieldType)
The location of the array the selection came from (ex, point, cell or field) 0

The value must be one of the following: CELL (0), POINT (1).

 
Frustum
(Frustum)
Vertices that define a frustum for the selection source. 0 0 1 0 0 0 0 0 0 1 1 0 0 1 0 0 1 0 1 0 1 0 0 0 1 1 1 0 1 1 0 0  
IDs
(IDs)
The list of IDs that will be added to the selection produced by the selection source.    
Inside Out
(InsideOut)
When this property is false the selection describes everything that should be extracted. When this is true the selection describes everything that should NOT be extracted. 0

Only the values 0 and 1 are accepted.

 
Locations
(Locations)
The list of locations that will be added to the selection produced by the selection source.    
Preserve Topology
(PreserveTopology)
If this property is set to 1 the output preserves the topology of its input and adds an insidedness array to mark which cells are inside or out. If 0 then the output is an unstructured grid which contains only the subset of cells that are inside. 0

Only the values 0 and 1 are accepted.

 
Show Bounds
(ShowBounds)
For frustum selection, if this property is set to 1 the output is the outline of the frustum instead of the contents of the input that lie within the frustum. 0

Only the values 0 and 1 are accepted.

 
Thresholds
(Thresholds)
The list of thresholds that will be added to the selection produced by the selection source.
