Hi Monica,

Thank you for your reply.

It looks like "flips" implements the (2,3) and its inverse, but not the (2,6) and (4,4) moves + inverses.

Thank you!

Look for "flips" in

If it does not provide everything you need, we could add more in CGAL.

Best,

Hello all,

Before I start implementing my own version, are there Pachner moves
defined in CGAL for triangulations?

Pachner, Udo. “P.L. Homeomorphic Manifolds Are Equivalent by Elementary
Shellings.” /European Journal of Combinatorics/ 12, no. 2 (March 1991):
129–45. doi:10.1016/S0195-6698(13)80080-7.

Thanks,
