To create an instance of class vtkIncrementalPointLocator, simply invoke its constructor as follows
obj = vtkIncrementalPointLocator
obj
is an instance of the vtkIncrementalPointLocator class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkIncrementalPointLocator = obj.NewInstance ()
vtkIncrementalPointLocator = obj.SafeDownCast (vtkObject o)
obj.Initialize ()
- Delete the search structure.
vtkIdType = obj.FindClosestInsertedPoint (double x[3])
- Given a point x assumed to be covered by the search structure, return the
index of the closest point (already inserted to the search structure)
regardless of the associated minimum squared distance relative to the
squared insertion-tolerance distance. This method is used when performing
incremental point insertion. Note -1 indicates that no point is found.
InitPointInsertion() should have been called in advance.
int = obj.InitPointInsertion (vtkPoints newPts, double bounds[6])
- Initialize the point insertion process. newPts is an object, storing 3D
point coordinates, to which incremental point insertion puts coordinates.
It is created and provided by an external VTK class. Argument bounds
represents the spatial bounding box, into which the points fall.
int = obj.InitPointInsertion (vtkPoints newPts, double bounds[6], vtkIdType estSize)
- Initialize the point insertion process. newPts is an object, storing 3D
point coordinates, to which incremental point insertion puts coordinates.
It is created and provided by an external VTK class. Argument bounds
represents the spatial bounding box, into which the points fall.
vtkIdType = obj.IsInsertedPoint (double x, double y, double z)
- Determine whether or not a given point has been inserted. Return the id of
the already inserted point if true, else return -1. InitPointInsertion()
should have been called in advance.
vtkIdType = obj.IsInsertedPoint (double x[3])
- Determine whether or not a given point has been inserted. Return the id of
the already inserted point if true, else return -1. InitPointInsertion()
should have been called in advance.
obj.InsertPoint (vtkIdType ptId, double x[3])
- Insert a given point with a specified point index ptId. InitPointInsertion()
should have been called prior to this function. Also, IsInsertedPoint()
should have been called in advance to ensure that the given point has not
been inserted unless point duplication is allowed.
vtkIdType = obj.InsertNextPoint (double x[3])
- Insert a given point and return the point index. InitPointInsertion()
should have been called prior to this function. Also, IsInsertedPoint()
should have been called in advance to ensure that the given point has not
been inserted unless point duplication is allowed.
