Alternating Neighborhoods Cyclic Cellular Automata

Idea

What happens when you combine the Alternating Neighborhoods with Cyclic Cellular Automata? This was an idea emailed to me from Asher (check out his blog and YouTube).

Range 1 Neighborhoods

Firstly for CCAs that only use neighbor cells within a range of a single cell. Rather than check all 8 neighbor cells each step of the CA, the neighborhood cells alternate between the following neighborhoods each cycle. The green square is the current cell being processed and the red squares are the neighborhood cells counted.

Range 1 Results

Expanding Stripes – Range 1 – Threshold 1 – States 3

Large Spirals – Range 1 – Threshold 1 – States 15

Spirals – Range 1 – Threshold 2 – States 4

Range 2 Neighborhoods

And then I also extended the neighborhoods to Range 2 and I give the option to use either of the following layouts.

The second neighborhoods tend to give more squarish shaped spirals compared to the first neighborhoods.

The usual CCA rules apply, but the neighborhoods above are used to calculate the count of values that is checked against the threshold.

Range 2 Results

Dithered Spirals – Range 2 – Threshold 2 – States 5

Small Spirals Form In Larger Spirals – Range 2 – Threshold 2 – States 4

Stable Blobs – Range 2 – Threshold 7 – States 2

Availability

Alternating Neighborhoods Cyclic Cellular Automata are now included in Visions of Chaos.

Visions of Chaos movie tutorials

For years now I have been asked for some more in depth tutorials on Visions of Chaos. One recent comment on my YouTube said a movie watching me use it may help them.

I have wanted to do movie tutorials but I was never happy with my voice. After doing these first 3 parts I have nothing but the utmost respect for anyone that can do this easily. Even with a full script pre-written of what I want to say it is not easy.

I used the free OBS Studio to capture my screen and then the Davinci Resolve free version for editing. Davinci has been great for chopping out all my seemingly endless umms, errs, pauses, stutters, flubbed lines, etc. It does crash frequently on multiple PCs when rendering to the final movie, but this looks like a graphics driver issue as when I use it on a very old PC it works fine without crashing. Hopefully the next Nvidia updates will stabilize the performance again.

For the first 3 tutorials I used a super cheap headset with a built in microphone so the sound is very rough, but hopefully they can help people and get some feedback on other areas of the program people want tutorials on.

After buying a better microphone I recorded the following TensorFlow tutorials.

There are occasional very low end thumping noises. They were a mystery at first (sounds almost like construction noise, but there was none that I could hear at the time of recording) but turned out to be the lift in my building. Otherwise you may hear cicadas and other Australian wildlife in the background.

Another tutorial about the Physarum Simulations in Visions of Chaos.

Number 6 is a more relaxed non-scripted tutorial on Video Feedback simulation. This one was a bugger to edit.

The 7th tutorial covers how to print Mandelbrot Fractals across multiple pages to make large wall sized posters.

The 8th tutorial covers DeepDream functionality in more depth.

The 9th is all about Style Transfer

I wouldn’t say I am getting good at this yet, but the recording and editing process is getting easier. If you have any specific requests for tutorial topics let me know.
