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.

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.

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.
