David,

Thanks for the note! Mangrove TDS looks interesting!

Good Morning,sorry, if you consider this message as an OT. In case, please delete this message. At the moment, I am studying and comparing the CGAL and other libraries for geometry processing, meshing, and so on. In particular, I am trying to identify what operations may be more important in any mesh database.If it may be useful, then you find dimension-independent implementations (on simplicial d-complexes, for any d) of these editing operators (direct and inverse) for all topological data structures, that are currently implemented in any plugin in the Mangrove TDS Library (http://mangrovetds.sourceforge.net). Member functions splitTopEntity and unsplitTopEntity should be of interest for your purposes and for their porting (maybe) in CGAL. I also guess that these operators should be implemented.Best regardsDavid Canino2015-02-03 17:03 GMT+01:00 Monique Teillaud <>:Hi Adam,
Thank you for the precisions. You are right, we don't have the other two.
I guess that we could/should add them...

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!

Hi,
Look for "flips" in

<http://doc.cgal.org/latest/TDS_3/classTriangulationDataStructure__3.html>
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?
