Hello,

There is a feature under development that adds support for periodic 
triangulations of such domain. You can find a stable (but unfinished) 
version here : 
https://github.com/MaelRL/cgal/tree/Generic_Periodic_Triangulations 
<https://github.com/MaelRL/cgal/tree/Generic_Periodic_Triangulations>.

In this new version of the package, the base domain that is periodically 
duplicated is a Voronoi face, described by a lattice basis of vectors; 3 
vectors in your 2D case. See the associated paper : 
https://drops.dagstuhl.de/opus/volltexte/2020/12941/pdf/LIPIcs-ESA-2020-75.pdf 
<https://drops.dagstuhl.de/opus/volltexte/2020/12941/pdf/LIPIcs-ESA-2020-75.pdf> 
for more details, explanations on how it works, etc.

The code is developed in the existing package 
"Periodic_2_triangulation_2" (and "Periodic_3_triangulation_3" for the 
3D version). You should base your code on this example : 
https://github.com/MaelRL/cgal/blob/Generic_Periodic_Triangulations/Periodic_2_triangulation_2/examples/Periodic_2_triangulation_2/generic_p2t2.cpp 
<https://github.com/MaelRL/cgal/blob/Generic_Periodic_Triangulations/Periodic_2_triangulation_2/examples/Periodic_2_triangulation_2/generic_p2t2.cpp>.

Let me know if you encounter any issue or have any question.

Best,
Mael
