How to perform an edge flip

[Alan-Leo-Wong]

Hi, could you tell me how to perform an edge flip for a given mesh?

I’m currently working on a task where I’ve used a mesh's vertices as seeds to compute a restricted Delaunay triangulation in surfacic mode. I want to flip some of the edges between vertices in the triangulation to restore the connectivity structure of the original mesh. However, I seem to be unable to find any relevant functions for performing edge flips.

Hello, there is no function to perform an edge flip in geogram, but you can easily implement it, by using mesh.facet_corners.set_vertex() and mesh.facet_corners.set_opposite_facet(). In the end it will be very similar to
this code in the constrained 2D triangulation but beware the indexing is different.
