The optional messages (verbose) were improved in both files:
OFF_to_nef_3.h
vertex_cycle_to_nef_3.h
Correction in OFF_to_nef_3.h:
old: V.reserve(NOI);
new: V_f.reserve(NOI);
Changes in vertex_cycle_to_nef_3.h
The meaning of the parameter 'normal' is now less mandatory.
Because of this, the structure of the funtion body slightly changed.
