Detailed Description

template<typename PermutationStorage = VTKM_DEFAULT_STORAGE_TAG>
class vtkm::worklet::ScatterPermutation< PermutationStorage >

A scatter that maps input to output based on a permutation array.

The Scatter classes are responsible for defining how much output is generated based on some sized input. ScatterPermutation is similar to ScatterCounting but can have lesser memory usage for some cases. The constructor takes an array of ids, where each entry maps the corresponding output to an input. The ids can be in any order and there can be duplicates. Note that even with duplicates the VistIndex is always 0.
