Detailed Description

perform fast cell location operations

vtkStaticCellLocator is a type of vtkAbstractCellLocator that accelerates certain operations when performing spatial operations on cells. These operations include finding a point that contains a cell, and intersecting cells with a line.

vtkStaticCellLocator is an accelerated version of vtkCellLocator. It is threaded (via vtkSMPTools), and supports one-time static construction (i.e., incremental cell insertion is not supported).

Warning
This class is templated. It may run slower than serial execution if the code is not optimized during compilation. Build in Release or ReleaseWithDebugInfo.
This class always caches cell bounds.

void vtkStaticCellLocator::FindCellsWithinBounds ( double bbox,

Return a list of unique cell ids inside of a given bounding box.

The user must provide the vtkIdList to populate. This method returns data only after the locator has been built.

Reimplemented from vtkAbstractCellLocator.

void vtkStaticCellLocator::FindCellsAlongLine ( const double  p1[3],
const double  p2[3],
double  tolerance,

)
overridevirtual

Given a finite line defined by the two points (p1,p2), return the list of unique cell ids in the buckets containing the line.

It is possible that an empty cell list is returned. The user must provide the vtkIdList cell list to populate. This method returns data only after the locator has been built.

Reimplemented from vtkAbstractCellLocator.

void vtkStaticCellLocator::FindCellsAlongPlane ( const double  o[3],
const double  n[3],
double  tolerance,

)

Given an unbounded plane defined by an origin o[3] and unit normal n[3], return the list of unique cell ids in the buckets containing the plane.

It is possible that an empty cell list is returned. The user must provide the vtkIdList cell list to populate. This method returns data only after the locator has been built.

void vtkStaticCellLocator::FindClosestPoint ( const double  x[3],
double  closestPoint[3],
vtkGenericCell cell,
vtkIdType cellId,
int subId,
double dist2 
)
overridevirtual

Return the closest point and the cell which is closest to the point x.

The closest point is somewhere on a cell, it need not be one of the vertices of the cell. This version takes in a vtkGenericCell to avoid allocating and deallocating the cell. This is much faster than the version which does not take a *cell, especially when this function is called many times in a row such as by a for loop, where the allocation and deallocation can be done only once outside the for loop. If a cell is found, "cell" contains the points and ptIds for the cell "cellId" upon exit.

Reimplemented from vtkAbstractCellLocator.

The cell is returned as a cell id and as a generic cell.

virtual void vtkStaticCellLocator::SetMaxNumberOfBuckets ( vtkIdType  )
virtual

Set the maximum number of buckets in the locator.

By default the value is set to VTK_INT_MAX. Note that there are significant performance implications at work here. If the number of buckets is set very large (meaning > VTK_INT_MAX) then internal sorting may be performed using 64-bit integers (which is much slower than using a 32-bit int). Of course, memory requirements may dramatically increase as well. It is recommended that the default value be used; but for extremely large data it may be desired to create a locator with an exceptionally large number of buckets. Note also that during initialization of the locator if the MaxNumberOfBuckets threshold is exceeded, the Divisions are scaled down in such a way as not to exceed the MaxNumberOfBuckets proportionally to the size of the bounding box in the x-y-z directions.

virtual vtkIdType vtkStaticCellLocator::GetMaxNumberOfBuckets ( )
virtual

Set the maximum number of buckets in the locator.

By default the value is set to VTK_INT_MAX. Note that there are significant performance implications at work here.

bool vtkStaticCellLocator::GetLargeIds ( )
inline

Inform the user as to whether large ids are being used.

This flag only has meaning after the locator has been built. Large ids are used when the number of binned points, or the number of bins, is >= the maximum number of buckets (specified by the user). Note that LargeIds are only available on 64-bit architectures.
