This isn’t something new, but a feature that was on my to do list for years after seeing it implemented elsewhere.
The idea is simple. You take a 2D CA and rather than render each step/cycle/update as a 2D image, you add the current 2D cell states as a layer of a 3D stack of cubes. Each slice of the cube is another step in the CA generation.
These examples are of History Dependent Cellular Automata.
Once again I must give a shout out to the most excellent Mitsuba Renderer. I would not be able to render these examples with such nicely shaded cubes without it.
Visions of Chaos now supports generating 2D Cellular Automata, History Dependent Cellular Automata and Indexed Totalistic Cellular Automata as stacked generations.
I have been exploring a variety of cellular automata lately and here is another one.
This is from another idea I had. I am not sure if this is unique, but a quick hunt found no matching CAs. If it is a duplicate of an existing named rule, let me know.
This is a totalistic CA that uses the usual 8 immediate neighbor cells as well as the last step’s current cell and 8 neighbors. This gives a total of 17 neighbor cells that can influence the birth and survival of the cells.
I call them “History Dependent Cellular Automata” because they depend on the previous cycles’ neighbor cells as well as the usual 8 immediate neighbor cells.
Here are a few animated GIFS showing some early results. The GIF thumbnails are messy, so click them to see the clear GIFs.
The CA is now a new mode included with Visions of Chaos if you want to have a play with it.
