Nice city!
Are the cells generated with a normal in the texture or are random boxes
placed using the normal?
Can I see the source?
Thank you,
Paolo

Looks like the cell pattern used as a hight field or an isosurface.

Mmm. I've replicated the outline of the heightfield using a bozo
pigment, but not the normal: I'm not able to obtain such big cells using
cell pattern as normal.

Hi, this may still be a bit obfuscated; I didn't check that every single line

Thank you, gregjohn!
I have understand now: in my tests I have used a simple texture with
normal, but the trick is done using a texture_map.
I like works like these, simple but evocative,
