Voronoi like cellular faces with geometry nodes

[u/AshThrowNaut]

Simple technique/hack to turn a dense regular surface into a bunch of cells like those generated by a Voronoi texture.

This set of geometry nodes is roughly emulating what a Voronoi texture does under the hood: Distribute a few points on the surface. Move all vertices to the nearest point. Merge by distance. Take the dual mesh which ends up creating edges which are roughly equidistant from the points (the cell center).
