Class designed to help with merging of points in parallel.
vtkSMPMergePoints is a subclass of vtkMergePoints designed to help with merging of points generated by using multiple locators in parallel. Its main functionality is provided by the Merge function. It also has a few additional convenience functions. Merge is thread safe as long as no two threads are merging the same bin. The common way of using vtkSMPMergePoints is:
- Initialize with outLocator->InitializeMerge()
- Allocate points with outLocator->GetPoints()->Resize(numPts) (numPts should be >= total number of points)
- Do bunch of merging with outLocator->Merge(inLocator[i], ...) (this can be done in parallel as long as no two bins are done at the same time)
- Fix the size of points with outLocator->FixSizeOfPointArray()
