Multi-channel ecosystem with a four-dimensional organism
Chan (2020) · Sebastian & Claude (mmxxvi)
Lenia's Expanded Universe (Chan, 2020) extends the original continuous cellular automaton with multiple interacting channels. Here three of them form an ecology — prey feed predators, predators suppress prey, and a morphogen field diffuses between them carrying a chemical memory of who has been where. The fourth channel is something else.
The Dihypersphaerome ventilans (Chan, animals4D) is a 4D organism whose shells match the β=[1/12, 1/6, 1] kernel topology. Rotating it through XW, YW, and ZW planes produces a 2D cross-section that “ventilates” — breathes in and out — as its fourth-dimensional structure sweeps past the plane. That shadow bleeds into the prey channel as generative seed.
Read the report →- Predation flashes. Where prey and predator overlap, the field turns brilliant green — the moment of contact, vivid and brief.
- Morphogen memory.A subtle teal tint lingers after creatures move on. The field remembers who has been where, and that memory feeds the prey channel's σ — kinder physics where the trail is fresh.
- Ventilating shadow. Load the DV Seedpreset and watch the violet wisps pulse. The rhythm is the 4D organism's rotation through its W-axis — the shadow you see is a 2D cross-section of a 4D body breathing in and out through the plane.
- Advection currents. Switch to the Flow secondary view — colours map to velocity direction, brightness to speed. Ecosystem scale becomes fluid.
