cellular automata vst?

[tibor]

for developers... a midi plugin or a synth based on cellular automata like this » http://en.wikipedia.org/wiki/Conway%27s_Game_of_Life (video with it applied for audio here » http://www.vimeo.com/320666) would probably be interesting for some people and some kinds of music.

the simplest way i know of coding conway's game of life is in processing (www.processing.org) but since it's based in java it's pretty much crap for audio without using extra code libraries. still... it's in the code examples that come with processing. if anyone is up for trying to code something out as a vst plugin... here's the processing code for inspiration:

/**
* Conway's Game of Life
* by Mike Davis.
*
* This program is a simple version of Conway's
* game of Life. A lit point turns off if there
* are fewer than two or more than three surrounding
* lit points. An unlit point turns on if there
* are exactly three lit neighbors. The 'density'
* parameter determines how much of the board will
* start out lit.
*
* Created 3 August 2002
*/

int sx, sy;
float density = 0.5;
int[][][] world;

void setup()
{
size(200, 200);
frameRate(12);
sx = width;
sy = height;
world = new int[sx][sy][2];
stroke(255);

// Set random cells to 'on'
for (int i = 0; i < sx * sy * density; i++) {
world[(int)random(sx)][(int)random(sy)][1] = 1;
}
}

void draw()
{
background(0);

// Drawing and update cycle
for (int x = 0; x < sx; x=x+1) {
for (int y = 0; y < sy; y=y+1) {
//if (world[x][y][1] == 1)
// Change recommended by The.Lucky.Mutt
if ((world[x][y][1] == 1) || (world[x][y][1] == 0 && world[x][y][0] == 1))
{
world[x][y][0] = 1;
point(x, y);
}
if (world[x][y][1] == -1)
{
world[x][y][0] = 0;
}
world[x][y][1] = 0;
}
}
// Birth and death cycle
for (int x = 0; x < sx; x=x+1) {
for (int y = 0; y < sy; y=y+1) {
int count = neighbors(x, y);
if (count == 3 && world[x][y][0] == 0)
{
world[x][y][1] = 1;
}
if ((count < 2 || count > 3) && world[x][y][0] == 1)
{
world[x][y][1] = -1;
}
}
}
}

// Count the number of adjacent cells 'on'
int neighbors(int x, int y)
{
return world[(x + 1) % sx][y][0] +
world[x][(y + 1) % sy][0] +
world[(x + sx - 1) % sx][y][0] +
world[x][(y + sy - 1) % sy][0] +
world[(x + 1) % sx][(y + 1) % sy][0] +
world[(x + sx - 1) % sx][(y + 1) % sy][0] +
world[(x + sx - 1) % sx][(y + sy - 1) % sy][0] +
world[(x + 1) % sx][(y + sy - 1) % sy][0];
}

evm made a 'conway's game of life' sem for synthedit a few months ago.

i'm still waiting to hear back about redistribution as etric announced he wasn't releasing sems any more.

i have a 'behavioural algorithm' for generating called populus, which could be categorised as a c.a. it's available in the current "freeware" edition of computer music magazine, or with any other license purchase :p

tho if you can copy that, you can probably paste it into an sdk yourself

I'd love to see more of this kind of thing.
Still, I know of a couple related examples:

Hansje made a game-of-life in Bidule (which has a VST version):

Also, there is a game-of-life sequencer in Reaktor:

The Bidule link is 2 years old and has timed out - any chance of uploading it somewhere?

I would love to see a vst version of glitchDS, which you can check out at www.glitchds.com if you have a Nintendo DS. His RepeaterDS is also fantastic. And what's more, not only are the results good, the process is a lot of fun, as well. A vst version of glitchDS with midi out would make me very happy.

Check out this video of an older version:

You can download it using the Group Manager built into Bidule.
Open Bidule,
click Tools,
select Group Manager,
click Get Remote Catalog,
look for/select Game of Life,
click Download.

Thanks - all I can see when I do that are 8 ensembles but not Game of Life

[allofdrab]

huh, I don't know, I get around 150 - 200 groups on mine.

Here's a fun little toy that'll generate a midi file for you:

We might have something in this vein on the way. Maybe. Possibly.

vvvv just became a VST host!
Here's a Game Of Life done with it:

for developers... a midi plugin or a synth based on cellular automata like this » http://en.wikipedia.org/wiki/Conway%27s_Game_of_Li fe (video with it applied for audio here » http://www.vimeo.com/320666) would probably be interesting for some people and some kinds of music.

No I dont actually think the Kohonen Maps are interestings...

What are the Kohonen Maps?

What are the Kohonen Maps?

Absolutely nothing related to cellular automata, basically.

A self-organizing map (SOM) is a type of artificial neural network that is trained using unsupervised learning to produce a low-dimensional (typically two dimensional), discretized representation of the input space of the training samples, called a map. The map seeks to preserve the topological properties of the input space.

This makes SOM useful for visualizing low-dimensional views of high-dimensional data, akin to multidimensional scaling. The model was first described as an artificial neural network by the Finnish professor Teuvo Kohonen, and is sometimes called a Kohonen map.

This subject rather interesting. Probably since then nothing changed.
It is time to begin VST development of cellular automata
What any ideas?
