Aggregates data sets to a reduced number of processes.
int RequestData(vtkInformation *request, vtkInformationVector **inputVector, vtkInformationVector *outputVector) override
This is called within ProcessRequest when a request asks the algorithm to do its work.
bool DoExtentsOverlap(int extent1[6], int extent2[6], int dimensions[3], int *overlappingExtent)
Given two extents and dimensions (marking whether or not we have cells in that dimension with a value...
void ExtractRectilinearGridCoordinates(int *sourceExtent, int *targetExtent, vtkDataArray *sourceCoordinates, vtkDataArray *targetCoordinates)
Put appropriate values from sourceCoordinates into targetCoordinates based on the extents overlap.
int GetTargetProcessId(int sourceProcessId, int numberOfProcesses)
Given a source process id and number of processes, return a target process id for the aggregate opera...
