Detailed Description

provides a method for sorting field data

vtkSortFieldData is used to sort data, based on its value, or with an associated key, into either ascending or descending order. This is useful for operations like selection, or analysis, when evaluating and processing data.

This class, which extends the base functionality of vtkSortDataArray, is used to sort field data and its various subclasses (vtkFieldData, vtkDataSetAttributes, vtkPointData, vtkCellData, etc.)

Warning
This class has been threaded with vtkSMPTools. Using TBB or other non-sequential type (set in the CMake variable VTK_SMP_IMPLEMENTATION_TYPE) may improve performance significantly on multi-core machines.
The sort methods below are static, hence the sorting methods can be used without instantiating the class. All methods are thread safe.

◆ Sort() [1/2]

static vtkIdType * vtkSortFieldData::Sort ( vtkFieldData fd,

)
inlinestatic

Given field data (and derived classes such as point data and cell data), sort all the arrays in the field data given an array and a component number k from that array.

In other words, if an array has n components, the kth component is used to sort the array and all of the other arrays in the field data. Also note that the user can indicate whether the function returns the sort indices (returnIndices=1). If the indices are returned, then the user takes ownership of the data and must delete it. Note that the indices are in sorted (ascending) order, and indicate the final sorted position of the sort. So for example indices[0]=10 indicates that the original data in position 10 in the field, was moved to position 0 after the sort. By default, returnIndices=0. (Other notes: if any array is not the same length as the sorting array, then it will be skipped and not sorted.)

◆ Sort() [2/2]

static vtkIdType * vtkSortFieldData::Sort ( vtkFieldData fd,
const char *  arrayName,
int  k,
int  returnIndices,
int  dir 
)
static

Given field data (and derived classes such as point data and cell data), sort all the arrays in the field data given an array and a component number k from that array.

In other words, if an array has n components, the kth component is used to sort the array and all of the other arrays in the field data. The order of the sorted data is goven by dir: dir=0 means sort in ascending order; dir=1 means sort in descending order. Also note that the user can indicate whether the function returns the sort indices (returnIndices=1). If the indices are returned, then the user takes ownership of the data and must delete it. Note that the indices are always in sorted (ascending) order, and indicate the final sorted position of the sort. So for example indices[0]=10 indicates that the original data in position 10 in the field, was moved to position 0 after the sort (i.e., position 0 is the smallest value). However, if sort direction dir=1, the indices do not change but the final shuffle of the data is in reverse order (note idx[n-1] for n keys is the largest value). By default, returnIndices=0. (Other notes: if any array is not the same length as the sorting array, then it will be skipped and not sorted.)
