voronoi 🤯 🤩 😃

speechless 😅

Once I get going on this soon imma be asking about more voronoi’s.

Still lots of reading and review and testing lol.

Also i think this person makes a very good point:

> Is it possible, using Isopod or otherwise, to create a lattice structure that follows the shape of an object, rather than just being orthogonal (?) So take the mesh in the attached file… rather than the lattice filling the bounding box of the shape and being trimmed to the shape’s boundary, create a lattice that is morphed to flow along the shape? Controlling the density of the lattice along the shape so it could be denser in the middle or ends?

looking forward to playing with isopods 😃 🤩
