Go here and click "constant generation"
Man I was bored, a long time ago, so I created a low quality canvas polygon evolver. It does fairly dumb and neat crap like this:
If you leave it on absurdly long, it does this instead:
The power of dice!
Start with an image. Create a canvas of the same size. Create a function f(Pix1,Pix2) that returns a number [0..1] on how similar two pixels' colors are. Take the average of that function over every matched pixel in the two images. Pow: a measure of "image similarity."
Now, create a pool of random "image genomes," which are just lists of polygons to draw deepest-first in flat color. Randomly add or modify features and colors, keeping the "most similar" and murdering the remainder.
It's easier when you see it. Start with a Lisa Edelstein.
After around 50,000 generations:
At 200,000:
At 500,000:
And a million (Dr. Evil finger):
Because this is javascript, it's extremely fast. (checks notes) Wait, no.
Also I have applied approximately zero careful effort to this. So you can expect a display quality piece to take 30-40 minutes on a quad-2.4. Chrome's canvas implementation is dramatically faster than the competition at time of writing, and will do the work as such much much faster.
I mean, let's be direct. This is not good code. I was pretty drunk the night I wrote this. I just don't care enough to fix it.
canvolver is MIT licensed, because viral licenses and newspeak language modification are evil. Free is only free when it's free for everyone.
... but you should not want this code. Not even in jest.
