Usage
Generates a new vtkIdTypeArray containing zero-base indices.
vtkGenerateIndexArray operates in one of two distinct
"modes". By default, it simply generates an index array
containing monotonically-increasing integers in the range
[0, N), where N is appropriately sized for the field type
that will store the results. This mode is useful for
generating a unique ID field for datasets that have none.
The second "mode" uses an existing array from the input data
object as a "reference". Distinct values from the reference
array are sorted in ascending order, and an integer index in
the range [0, N) is assigned to each. The resulting map is
used to populate the output index array, mapping each value
in the reference array to its corresponding index and
storing the result in the output array. This mode is
especially useful when generating tensors, since it allows
us to "map" from an array with arbitrary contents to an
index that can be used as tensor coordinates.
To create an instance of class vtkGenerateIndexArray, simply
invoke its constructor as follows
obj = vtkGenerateIndexArray
Methods
The class vtkGenerateIndexArray has several methods that can
be used. They are listed below. Note that the documentation
is translated automatically from the VTK sources, and may
not be completely intelligible. When in doubt, consult the
VTK website. In the methods listed below, obj is an instance
of the vtkGenerateIndexArray class.
* string = obj.GetClassName ()
* int = obj.IsA (string name)
* vtkGenerateIndexArray = obj.NewInstance ()
* vtkGenerateIndexArray = obj.SafeDownCast (vtkObject o)
* obj.SetArrayName (string ) - Control the output index
array name. Default: "index".
* string = obj.GetArrayName () - Control the output index
array name. Default: "index".
* obj.SetFieldType (int ) - Control the location where the
index array will be stored.
* int = obj.GetFieldType () - Control the location where the
index array will be stored.
* obj.SetReferenceArrayName (string ) - Specifies an
optional reference array for index-generation.
* string = obj.GetReferenceArrayName () - Specifies an
optional reference array for index-generation.
* obj.SetPedigreeID (int ) - Specifies whether the index
array should be marked as pedigree ids. Default: false.
* int = obj.GetPedigreeID () - Specifies whether the index
array should be marked as pedigree ids. Default: false.
