Detailed Description

abstract class to quickly locate points in 3-space

vtkAbstractPointLocator is an abstract spatial search object to quickly locate points in 3D. vtkAbstractPointLocator works by dividing a specified region of space into "rectangular" buckets, and then keeping a list of points that lie in each bucket. Typical operation involves giving a position in 3D and finding the closest point. The points are provided from the specified dataset input.

virtual const char* vtkAbstractPointLocator::GetClassName (  )  [virtual]

Reimplemented from vtkLocator.

Reimplemented in vtkKdTreePointLocator, vtkMergePoints, and vtkPointLocator.

static int vtkAbstractPointLocator::IsTypeOf ( const char *  name  )  [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkLocator.

Reimplemented in vtkKdTreePointLocator, vtkMergePoints, and vtkPointLocator.

virtual int vtkAbstractPointLocator::IsA ( const char *  name  )  [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkLocator.

Reimplemented in vtkKdTreePointLocator, vtkMergePoints, and vtkPointLocator.

static vtkAbstractPointLocator* vtkAbstractPointLocator::SafeDownCast ( vtkObject o  )  [static]

Reimplemented from vtkLocator.

Reimplemented in vtkKdTreePointLocator, vtkMergePoints, and vtkPointLocator.

void vtkAbstractPointLocator::PrintSelf ( ostream &  os,
vtkIndent  indent 
) [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 vtkLocator.

Reimplemented in vtkKdTreePointLocator, vtkMergePoints, and vtkPointLocator.

virtual vtkIdType vtkAbstractPointLocator::FindClosestPoint ( const double  x[3]  )  [pure virtual]

Given a position x, return the id of the point closest to it. Alternative method requires separate x-y-z values. These methods are thread safe if BuildLocator() is directly or indirectly called from a single thread first.

Implemented in vtkKdTreePointLocator, and vtkPointLocator.

vtkIdType vtkAbstractPointLocator::FindClosestPoint ( double  x,
double  y,
double  z 
)

Given a position x, return the id of the point closest to it. Alternative method requires separate x-y-z values. These methods are thread safe if BuildLocator() is directly or indirectly called from a single thread first.

virtual vtkIdType vtkAbstractPointLocator::FindClosestPointWithinRadius ( double  radius,
const double  x[3],
double &  dist2 
) [pure virtual]

Given a position x and a radius r, return the id of the point closest to the point in that radius. dist2 returns the squared distance to the point.

Implemented in vtkKdTreePointLocator, and vtkPointLocator.

virtual void vtkAbstractPointLocator::FindClosestNPoints ( int  N,
const double  x[3],
vtkIdList result 
) [pure virtual]

Find the closest N points to a position. This returns the closest N points to a position. A faster method could be created that returned N close points to a position, but necessarily the exact N closest. The returned points are sorted from closest to farthest. These methods are thread safe if BuildLocator() is directly or indirectly called from a single thread first.

Implemented in vtkKdTreePointLocator, and vtkPointLocator.

void vtkAbstractPointLocator::FindClosestNPoints ( int  N,
double  x,
double  y,
double  z,
vtkIdList result 
)

Find the closest N points to a position. This returns the closest N points to a position. A faster method could be created that returned N close points to a position, but necessarily the exact N closest. The returned points are sorted from closest to farthest. These methods are thread safe if BuildLocator() is directly or indirectly called from a single thread first.

virtual void vtkAbstractPointLocator::FindPointsWithinRadius ( double  R,
const double  x[3],
vtkIdList result 
) [pure virtual]

Find all points within a specified radius R of position x. The result is not sorted in any specific manner. These methods are thread safe if BuildLocator() is directly or indirectly called from a single thread first.

Implemented in vtkKdTreePointLocator, and vtkPointLocator.

void vtkAbstractPointLocator::FindPointsWithinRadius ( double  R,
double  x,
double  y,
double  z,
vtkIdList result 
)

Find all points within a specified radius R of position x. The result is not sorted in any specific manner. These methods are thread safe if BuildLocator() is directly or indirectly called from a single thread first.
