|
| override void | BuildLocator () |
| | Load points from a dataset to construct an octree for point location. This function resorts to InitPointInsertion() to fulfill some of the work.
|
| override int | FindClosestInsertedPoint (IntPtr x) |
| | Given a point x assumed to be covered by the octree, return the index of the closest in-octree point 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.
|
| override void | FindClosestNPoints (int N, IntPtr x, vtkIdList result) |
| | Find the closest N points to a given point. The returned point ids (via result) are sorted from closest to farthest. BuildLocator() should have been called prior to this function. This method is thread safe if BuildLocator() is directly or indirectly called from a single thread first.
|
| override int | FindClosestPoint (IntPtr x) |
| | Given a point x, return the id of the closest point. BuildLocator() should have been called prior to this function. This method is thread safe if BuildLocator() is directly or indirectly called from a single thread first.

Note that BuildLocator() should have been called prior to this function. This method is thread safe if BuildLocator() is directly or indirectly called from a single thread first.
|
| int | FindClosestPointWithinSquaredRadius (double radius2, IntPtr x, ref double dist2) |
| | Given a point x and a squared radius radius2, return the id of the closest point within the radius and the associated minimum squared distance (via dist2, note this returned distance is valid only if the point id is not -1).

| | Get access to the vtkPoints object in which point coordinates are stored for either point location or point insertion.
|
| virtual int | GetMaxPointsPerLeaf () |
| | Set/Get the maximum number of points that a leaf node may maintain. Note that the actual number of points maintained by a leaf node might exceed this threshold if there is a large number (equal to or greater than the threshold) of exactly duplicate points (with zero distance) to be inserted (e.g., to construct an octree for subsequent point location) in extreme cases. Respecting this threshold in such scenarios would cause endless node sub-division. Thus this threshold is broken, but only in case of such situations.
|
| virtual int | GetMaxPointsPerLeafMaxValue () |
| | Set/Get the maximum number of points that a leaf node may maintain. Note that the actual number of points maintained by a leaf node might exceed this threshold if there is a large number (equal to or greater than the threshold) of exactly duplicate points (with zero distance) to be inserted (e.g., to construct an octree for subsequent point location) in extreme cases.

|
| virtual int | GetMaxPointsPerLeafMinValue () |
| | Set/Get the maximum number of points that a leaf node may maintain. Note that the actual number of points maintained by a leaf node might exceed this threshold if there is a large number (equal to or greater than the threshold) of exactly duplicate points (with zero distance) to be inserted (e.g., to construct an octree for subsequent point location) in extreme cases. Respecting this threshold in such scenarios would cause endless node sub-division. Thus this threshold is broken, but only in case of such situations.

|
| override int | InitPointInsertion (vtkPoints points, IntPtr bounds) |
| | Initialize the point insertion process. points is an object, storing 3D point coordinates, to which incremental point insertion put coordinates. It is created and provided by an external VTK class. Argument bounds represents the spatial bounding box, into which the points fall. In fact, an adjusted version of the bounding box is used to build the octree to make sure no any point (to be inserted) falls outside the octree. This function is not thread safe.
|
| override int | InitPointInsertion (vtkPoints points, IntPtr bounds, int estSize) |
| | Initialize the point insertion process. points is an object, storing 3D point coordinates, to which incremental point insertion put coordinates. It is created and provided by an external VTK class. Argument bounds represents the spatial bounding box, into which the points fall. In fact, an adjusted version of the bounding box is used to build the octree to make sure no any point (to be inserted) falls outside the octree. Argument estSize specifies the initial estimated size of the vtkPoints object. This function is not thread safe.
|
| override void | Initialize () |
| | Delete the octree search structure.
|
| override int | InsertNextPoint (IntPtr x) |
| | Insert a given point into the octree and return the point index. Note that InitPointInsertion() should have been called prior to this function. In addition, IsInsertedPoint() should have been called in advance to ensure that the given point has not been inserted unless point duplication is allowed (in this case, this function invovles a repeated leaf container location). vtkPoints::InsertNextPoint() is invoked.
|
| override void | InsertPoint (int ptId, IntPtr x) |
| | Insert a given point into the octree with a specified point index ptId. InitPointInsertion() should have been called prior to this function. In addition, IsInsertedPoint() should have been called in advance to ensure that the given point has not been inserted unless point duplication is allowed (Note that in this case, this function involves a repeated leaf container location). vtkPoints::InsertPoint() is invoked.
|
| void | InsertPointWithoutChecking (IntPtr point, ref int pntId, int insert) |
| | "Insert" a point to the octree without any checking. Argument insert means whether vtkPoints::InsertNextPoint() upon 1 is called or the point itself is not inserted to the vtkPoints at all but instead only the point index is inserted to a vtkIdList upon 0. For case 0, the point index needs to be specified via pntId. For case 1, the actual point index is returned via pntId. InitPointInsertion() should have been called.
|
| override int | InsertUniquePoint (IntPtr point, ref int pntId) |
| | Insert a point to the octree unless there has been a duplciate point. Whether the point is actually inserted (return 1) or not (return 0 upon a rejection by an existing duplicate), the index of the point (either new or the duplicate) is returned via pntId. Note that InitPointInsertion() should have been called prior to this function. vtkPoints::InsertNextPoint() is invoked. This method is not thread safe.

vtkIncrementalOctreePointLocator - Incremental octree in support of both point location and point insertion.
Description As opposed to the uniform bin-based search structure (adopted in class vtkPointLocator) with a fixed spatial resolution, an octree mechanism employs a hierarchy of tree-like sub-division of the 3D data domain. Thus it enables data-aware multi-resolution and accordingly accelerated point location as well as insertion, particularly when handling a radically imbalanced layout of points as not uncommon in datasets defined on adaptive meshes. Compared to a static point locator supporting pure location functionalities through some search structure established from a fixed set of points, an incremental point locator allows for, in addition, point insertion capabilities, with the search structure maintaining a dynamically increasing number of points. Class vtkIncrementalOctreePointLocator is an octree-based accelerated implementation of the functionalities of the uniform bin-based incremental point locator vtkPointLocator. For point location, an octree is built by accessing a vtkDataSet, specifically a vtkPointSet. For point insertion, an empty octree is inited and then incrementally populated as points are inserted. Three increasingly complex point insertion modes, i.e., direct check-free insertion, zero tolerance insertion, and non-zero tolerance insertion, are supported. In fact, the octree used in the point location mode is actually constructed via direct check-free point insertion. This class also provides a polygonal representation of the octree boundary.
