perform fast cell location operations
vtkStaticCellLocator is a type of vtkAbstractCellLocator that accelerates certain operations when performing spatial operations on cells. These operations include finding a point that contains a cell, and intersecting cells with a line.
vtkStaticCellLocator is an accelerated version of vtkCellLocator. It is threaded (via vtkSMPTools), and supports one-time static construction (i.e., incremental cell insertion is not supported).
vtkStaticCellLocator does NOT utilize the following parameters:

Set the maximum number of buckets in the locator.
By default the value is set to VTK_INT_MAX. Note that there are significant performance implications at work here. If the number of buckets is set very large (meaning > VTK_INT_MAX) then internal sorting may be performed using 64-bit integers (which is much slower than using a 32-bit int). Of course, memory requirements may dramatically increase as well. It is recommended that the default value be used; but for extremely large data it may be desired to create a locator with an exceptionally large number of buckets. Note also that during initialization of the locator if the MaxNumberOfBuckets threshold is exceeded, the Divisions are scaled down in such a way as not to exceed the MaxNumberOfBuckets proportionally to the size of the bounding box in the x-y-z directions.

By default the value is set to VTK_INT_MAX. Note that there are significant performance implications at work here. If the number of buckets is set very large (meaning > VTK_INT_MAX) then internal sorting may be performed using 64-bit integers (which is much slower than using a 32-bit int). Of course, memory requirements may dramatically increase as well. It is recommended that the default value be used; but for extremely large data it may be desired to create a locator with an exceptionally large number of buckets. Note also that during initialization of the locator if the MaxNumberOfBuckets threshold is exceeded, the Divisions are scaled down in such a way as not to exceed the MaxNumberOfBuckets proportionally to the size of the bounding box in the x-y-z directions.

Inform the user as to whether large ids are being used.
This flag only has meaning after the locator has been built. Large ids are used when the number of binned points, or the number of bins, is >= the maximum number of buckets (specified by the user). Note that LargeIds are only available on 64-bit architectures.

Return intersection point (if any) AND the cell which was intersected by the finite line.
The cell is returned as a cell id and as a generic cell.

Take the passed line segment and intersect it with the data set.
The return value of the function is 0 if no intersections were found. For each intersection with the bounds of a cell or with a cell (if a cell is provided), the points and cellIds have the relevant information added sorted by t. If points or cellIds are nullptr pointers, then no information is generated for that list.

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.

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. If a closest point is found, inside returns the return value of the EvaluatePosition call to the closest cell; inside(=1) or outside(=0).

Take the passed line segment and intersect it with the data set.
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. 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.
Either 'points' or 'cellIds' can be set to nullptr if you don't want to receive that information.
This method is only implemented in vtkOBBTree.
