Detailed Description

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()

virtual

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkMergePoints.

void vtkSMPMergePoints::InitializeMerge ( )

This should be called from 1 thread before any call to Merge.

void vtkSMPMergePoints::Merge	(	vtkSMPMergePoints *	locator,
		vtkIdType	idx,
		vtkPointData *	outPd,
		vtkPointData *	inPd,
		vtkIdList *	idList
	)

Merge the points of one of the bins from the given locator to the same bin of the current locator. Note that this requires that the two locators have identical binning structures. This also merges point data given in the inPD argument to the outPd. Furthermore, it generates a map of the old ids of the input locator to the new ids. This is stored in the idList argument. The map is idList[oldId] = newId.

void vtkSMPMergePoints::FixSizeOfPointArray ( )

At the of the merge, this can be called to set the MaxId of the points array to the maximum id in the locator. The current design usage is as follows: - Allocate points with points->Resize(numPts). NumPts should be >= total number of points - Do bunch of merging with outLocator->Merge(inLocator[i], ...) - Fix the size of points with outLocator->FixSizeOfPointArray()

vtkIdType vtkSMPMergePoints::GetMaxId ( )

inline

Returns the biggest id in the locator.

vtkIdType vtkSMPMergePoints::GetNumberOfIdsInBucket ( vtkIdType idx )

inline

Retuns the number of points in a bin.

vtkIdType vtkSMPMergePoints::GetNumberOfBuckets ( void )

inline

Retuns the number of bins.
