◆ IsTypeOf()

static vtkTypeBool vtkKdTreePointLocator::IsTypeOf ( const char *  type)
static

◆ IsA()

virtual vtkTypeBool vtkKdTreePointLocator::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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkAbstractPointLocator.

◆ SafeDownCast()

◆ NewInstanceInternal()

virtual vtkObjectBase* vtkKdTreePointLocator::NewInstanceInternal ( ) const

◆ New()

static vtkKdTreePointLocator* vtkKdTreePointLocator::New ( )
static

◆ PrintSelf()

void vtkKdTreePointLocator::PrintSelf ( ostream &  os,
vtkIndent  indent 
)
overridevirtual

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 vtkAbstractPointLocator.

◆ FindClosestPoint()

vtkIdType vtkKdTreePointLocator::FindClosestPoint ( const double  x[3])
overridevirtual

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.

Implements vtkAbstractPointLocator.

◆ FindClosestPointWithinRadius()

vtkIdType vtkKdTreePointLocator::FindClosestPointWithinRadius ( double  radius,
const double  x[3],
double &  dist2 
)
overridevirtual

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.

Implements vtkAbstractPointLocator.

◆ FindClosestNPoints()

void vtkKdTreePointLocator::FindClosestNPoints ( int  N,
const double  x[3],
vtkIdList result 
)
overridevirtual

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.

Implements vtkAbstractPointLocator.

◆ FindPointsWithinRadius()

void vtkKdTreePointLocator::FindPointsWithinRadius ( double  R,
const double  x[3],
vtkIdList result 
)
overridevirtual

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.

Implements vtkAbstractPointLocator.

◆ FreeSearchStructure()

void vtkKdTreePointLocator::FreeSearchStructure ( )
overridevirtual

See vtkLocator interface documentation.

These methods are not thread safe.

Implements vtkLocator.

◆ BuildLocator()

void vtkKdTreePointLocator::BuildLocator ( )
overridevirtual

Build the locator from the input dataset.

Implements vtkLocator.

◆ GenerateRepresentation()

void vtkKdTreePointLocator::GenerateRepresentation ( int  level,
vtkPolyData pd 
)
overridevirtual

Method to build a representation at a particular level.

Note that the method GetLevel() returns the maximum number of levels available for the tree. You must provide a vtkPolyData object into which to place the data.

Implements vtkLocator.
