I'm trying to create a dual mesh, as described by Alessandro Zomparelly, but procedurally using Geometry Nodes. I've only come this far, but now I need to dissolve the vertices of the original mesh, before triangulation and subdivision:

pre-dual mesh, vertices to remove

I'm not sure it's even possible with Geometry Nodes, but it should eventually end up like this:

Then, of course, the edges need to be cleaned up, so that's another challenge.

Is there a way to achieve this in Blender? I'm using the latest 2.93 Beta.

    $\begingroup$ I wouldn't be surprised if there wasn't any way to currently do this in geometry nodes. This feature is still very new and the mesh manipulation nodes are limited. In the meantime, if you want to be able to control a hex mesh using geometry nodes, perhaps (1) create the geometry you want in nodes, (2) create the hex mesh separately and (3) shrink-wrap the hex mesh onto your geometry. $\endgroup$ – Reinis Mazeiks Jun 3 at 8:09

    $\begingroup$ i agree with Reinis. AFAIK this is not possible at the moment. $\endgroup$ – Chris Jun 3 at 8:15
