## Detailed Description

merge exactly coincident points

Revision:
  1.43

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]`

| 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 vtkTypeRevisionMacro 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 vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkPointLocator.

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

| Reimplemented from vtkPointLocator.

void vtkMergePoints::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 vtkPointLocator.

vtkIdType 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.

vtkIdType 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. Reimplemented from vtkPointLocator. Definition at line 62 of file vtkMergePoints.h. References vtkPointLocator::IsInsertedPoint(), and vtkIdType.

int vtkMergePoints::InsertUniquePoint | ( | const float | x[3],
|  | vtkIdType & | 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.
