How to make hexagonal lines on the surface of the mesh

I want to make a like this picture, using the NGON plug-in to make hexagonal lines on the surface of the mesh

Because I want to use a curved surface to do it, but the grid will be irregular, so I want to use this grid to do it, okay?曲面六边形.gh (6.0 KB)

The Icon of NGon is created from dual of remeshed triangle mesh.

For such geometries use @DanielPiker TriMesh to remesh the geometry and create dual.

You can use NGon dual component to convert triangles to dual mesh.

The ‘Dual’ output of TriRemesh also outputs a dual mesh with similar area polygons directly
