Detailed Description

merge exactly coincident points.

Date:

2000/12/10 20:08:43

Revision:

1.35

vtkMergePoints is a locator object to quickly locate points in 3D. The primary difference between vtkMergePoints and its superclass vtkPointLocator is that vtkMergePoints merges precisely coincident points and is therefore much faster.

Member Function Documentation

vtkMergePoints* vtkMergePoints::New (    )  [static]

Construct with automatic computation of divisions, averaging 25 points per bucket. Reimplemented from vtkPointLocator.

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

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkPointLocator.

int vtkMergePoints::IsTypeOf (  const char *    type )  [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 vtkPointLocator.

virtual int vtkMergePoints::IsA (  const char *    type )  [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 vtkPointLocator.

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

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkPointLocator.

int vtkMergePoints::IsInsertedPoint (  const float    x[3] )  [virtual]

Determine whether point given by x[3] has been inserted into points list. Return id of previously inserted point if this is true, otherwise return -1. Reimplemented from vtkPointLocator.

int vtkMergePoints::IsInsertedPoint (  float    x, float    y, float    z )  [inline]

Determine whether point given by x[3] has been inserted into points list. Return id of previously inserted point if this is true, otherwise return -1. This method is thread safe. Reimplemented from vtkPointLocator. Definition at line 71 of file vtkMergePoints.h.

int vtkMergePoints::InsertUniquePoint (  const float    x[3], int &    ptId )  [virtual]

Determine whether point given by x[3] has been inserted into points list. Return 0 if point was already in the list, otherwise return 1. If the point was not in the list, it will be ADDED. In either case, the id of the point (newly inserted or not) is returned in the ptId argument. Note this combines the functionality of IsInsertedPoint() followed by a call to InsertNextPoint(). Reimplemented from vtkPointLocator.

void vtkMergePoints::operator= (  const vtkMergePoints &    )  [inline, protected]
