Delaunay mesh

Hello

Can someone tell me how to achieve this kind of design made on Ted Ngai's website. I presume it's a Delaunay triangulation at the base of the definition, but afterwards the way to achieve this design becomes a blur for me. Can someone help me with some ideas?

I don't know if this will be of much help but this tutorial should give you some idea

Thank you very much Sam.

Rough mesh from surface, with only triangles. Move, scale triangles, loft between original and transformed triangles, remesh lofts, catmull-clark or similar to make it round.

I think that should be enough, there are plenty of examples doing similar things with Voronois.

Hi Alberto,

You do not need to flatten the List item components and the offset component needed to be going in the opposite direction so I used the expression "-D" on that to make it work.

I have attached the working definition.

If you look at the Offset component, I have set the expression editor to be -D meaning that the Direction of the offset will be going the other way. I have attached images hopefully this makes more sense.
