  • Prompt: /* Cellular Lattice ---------------- Still playing around with 3D cellular tiles. Traversing a cellular, coral-like structure through an alien ocean ... Is anyone buying that? I don't know what it is either, but it looks grotesquely interesting. :) In technical terms, it's an intertwined sinusoidal lattice structure (a mutated gyroid of sorts) with a prominent cellular surface attached. The scene was mildly inspired by IQ's Leizex demo and Tomasz Dobrowolski's Suboceanic.
