Hello,

Is there a technical reason that the construction of barycentric coordinates for the Epick kernel is not specified or implemented? There is only a dummy placeholder in CGAL 5.1.

Is there a problem to implement the transform() method for Epick::Point objects ?

The mapping of cartesian to barycentric coordinates could be implemented as an affine transform.
The transform could be stored as Data in the full_cells of a Triangulation.


Regards,
