Member Function Documentation

static int vtkKdTreePointLocator::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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkAbstractPointLocator.

virtual int 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.

Reimplemented from vtkAbstractPointLocator.

virtual vtkObjectBase* vtkKdTreePointLocator::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkAbstractPointLocator.

Reimplemented from vtkAbstractPointLocator.

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

void vtkKdTreePointLocator::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 vtkAbstractPointLocator.

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

Implements vtkAbstractPointLocator.

virtual vtkIdType vtkKdTreePointLocator::FindClosestPointWithinRadius ( double  radius,
const double  x[3],
double dist2 
) [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.

Implements vtkAbstractPointLocator.

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

Implements vtkAbstractPointLocator.

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

Implements vtkAbstractPointLocator.

virtual void vtkKdTreePointLocator::FreeSearchStructure ( ) [virtual]

See vtkLocator interface documentation. These methods are not thread safe.

Implements vtkAbstractPointLocator.

virtual void vtkKdTreePointLocator::BuildLocator ( ) [virtual]

See vtkLocator interface documentation. These methods are not thread safe.

Implements vtkAbstractPointLocator.

virtual void vtkKdTreePointLocator::GenerateRepresentation ( int  level,
vtkPolyData pd 
) [virtual]

See vtkLocator interface documentation. These methods are not thread safe.

Implements vtkAbstractPointLocator.
