#include <CGAL/Spatial_lock_grid_3.h>
The class Spatial_lock_grid_3 allows to lock points with coordinates (x, y, z) in a 3D grid.
The point type is called P3 here. P3 must provide x(), y(), and z() functions, returning the respective point coordinates as numbers whose type is a model of the concept of RealEmbeddable.
It is a model of SurjectiveLockDataStructure, with T being P3 and S being the function that maps a point to the cell of the 3D grid containing this point.
For example, it can be used by concurrent algorithms to lock simplices.
| Grid_lock_tag | allows to choose the locking strategy used by the structure. The following tags are available:
