vtkAbstractCellLocator is a spatial search object to quickly locate cells in 3D. vtkAbstractCellLocator supplies a basic interface which concrete subclasses should implement.

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.

Specify the preferred/maximum number of cells in each node/bucket. Default 32. Locators generally operate by subdividing space into smaller regions until the number of cells in each region (or node) reaches the desired level.

Boolean controls whether the bounds of each cell are computed only once and then saved. Should be 10 to 20% faster if repeatedly calling any of the Intersect/Find routines and the extra memory won't cause disk caching (24 extra bytes per cell are required to save the bounds).

Most Locators build their search structures during BuildLocator but some may delay construction until it is actually needed. If LazyEvaluation is supported, this turns on/off the feature. if not supported, it is ignored.

Some locators support querying a new dataset without rebuilding the search structure (typically this may occur when a dataset changes due to a time update, but is actually the same topology) Turning on this flag enables some locators to skip the rebuilding phase

Take the passed line segment and intersect it with the data set. This method assumes that the data set is a vtkPolyData that describes a closed surface, and the intersection points that are returned in 'points' alternate between entrance points and exit points. The return value of the function is 0 if no intersections were found, -1 if point 'a0' lies inside the closed surface, or +1 if point 'a0' lies outside the closed surface. Either 'points' or 'cellIds' can be set to NULL if you don't want to receive that information. This method is currently only implemented in vtkOBBTree
Reimplemented in vtkCellTreeLocator, and vtkOBBTree.

Return the closest point and the cell which is closest to the point x. The closest point is somewhere on a cell, it need not be one of the vertices of the cell.
|
virtual |
Return the closest point and the cell which is closest to the point x. The closest point is somewhere on a cell, it need not be one of the vertices of the cell. This version takes in a vtkGenericCell to avoid allocating and deallocating the cell. This is much faster than the version which does not take a *cell, especially when this function is called many times in a row such as by a for loop, where the allocation and deallocation can be done only once outside the for loop. If a cell is found, "cell" contains the points and ptIds for the cell "cellId" upon exit.
Reimplemented in vtkCellLocator.
|
virtual |
Return the closest point within a specified radius and the cell which is closest to the point x. The closest point is somewhere on a cell, it need not be one of the vertices of the cell. This method returns 1 if a point is found within the specified radius. If there are no cells within the specified radius, the method returns 0 and the values of closestPoint, cellId, subId, and dist2 are undefined.

Return a list of unique cell ids inside of a given bounding box. The user must provide the vtkIdList to populate. This method returns data only after the locator has been built.

Given a finite line defined by the two points (p1,p2), return the list of unique cell ids in the buckets containing the line. It is possible that an empty cell list is returned. The user must provide the vtkIdList to populate. This method returns data only after the locator has been built.
Reimplemented in vtkCellLocator.
Returns the Id of the cell containing the point, returns -1 if no cell found. This interface uses a tolerance of zero
Reimplemented in vtkCellTreeLocator.

Find the cell containing a given point. returns -1 if no cell found the cell parameters are copied into the supplied variables, a cell must be provided to store the information.
Reimplemented in vtkModifiedBSPTree, vtkCellLocator, and vtkCellTreeLocator.
Quickly test if a point is inside the bounds of a particular cell. Some locators cache cell bounds and this function can make use of fast access to the data.
Reimplemented in vtkModifiedBSPTree.

This command is used internally by the locator to copy all cell Bounds into the internal CellBounds array. Subsequent calls to InsideCellBounds(...) can make use of the data A valid dataset must be present for this to work. Returns true if bounds wre copied, false otherwise.
