When we set the exact comparison tag to true, we use a lazy evaluation of predicates and store pointers to the arguments of the predicates (that is, pointer to points). However, the points are -- in the case of periodic -- only temporary objects and it is thus dangerous to take pointers to those temporary values because the pointers quickly become invalid. Thus, periodic triangulations are not allowed to use the exact tag. A possible way to make it work is to define a small class: Periodic_triangulation_with_stored_real_points that would inherit the base (periodic) triangulation but store all the points of its simplices. Then, the function point(face_handle, int) would return an entry of that container, of which it would be safe to take a pointer. |
