>>5747462>>5747480>>5747484The simplest way to do 3D is to take some simplex noise and use it to vary the z-axis (extrude the voronoi vertically, this is very easy in threejs there is some dedicated function) and you can create an interesting warhammer 40k necromunda hive city effect hehe.
I think though what you want and are referring to for space is like a honeycomb effect (not extruded, but each 3d voronoi cell vertex defined by some irregular shaped lattice volume etc) this is definitely possible but far harder. My original intention was to convert each of my random cuboid block towers in the demo here
